There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

LOL. I did, AND the big dog DID edit you.
Oh... you don't remember all of your COLORED CAPITALIZED text yelling either? I think someone may have slapped your hand about that. :cus:
But, you did challenge me! Went on about your credentials and how you won that super-cool drag race. YOU even said we would go for "pink slips." I literally spit out my drink when I saw "pink slips." Hadn't heard that term since the demise of "Joanie Loves Chachi."

OK King of " emoji " land .... the eight or nine laughing emoji's should have tipped you off to the fact that this post was a JOKE ...... I was Spoofing you and bought it :roflblack::roflblack::roflblack::roflblack::roflblack:..... toooooooooooo funny .........PS Lamont didn't EDIT or Delete anything.....because when the administrator delete's something it's Totally gone ...from the board, from the files even in your personal folder ..... It's like it NEVER existed. But like I said earlier " when the truth doesn't fit the discussion ( in your mind ) you just make things up " ...... Mike :thumbup:

That post in the screenshot was referencing what you put on my for sale items thread! Of course, it would be gone. He even let me know when he deleted your trollish comment. Better yet, he remembered it when I was with him a few weeks ago.
Like it says in the screenshot... I was an Admin for a website with over 250,000 users. Did it for 7 years. You are the definition of a troll. You may not be very internet savvy. So you can go to a place called "Google" and do a "search" for that term.

Back to the topic
OK, let's get back to the original topic of this thread. Here's pic of my General Altimax when I replaced it after about 17k+ miles running at 24 - 25 psi. I rode solo at least half the time, 200+ lbs., with no extra load and with the trunk and saddlebags filled and a large bag on the back seat with maybe 80+ lbs. for about 1/2 the time.
I'm running a Cooper CS5 Grand Touring now. Not enough miles on it yet to make a judgment about wear. I'm running it at around 18-20 psi.

Odd Tire wear pattern
I suppose I don't need to comment on the psi you were running this tire at ...... But what I find interesting is the odd wear pattern ......As shown in your pic there are three center strips , the left is most worn , then the middle, the right side is hardly worn compared to the other two ...... When wear shows up ( on tires ) it should be evenly distributed across the tread.....UNLESS that tire isn't tracking TRUE ...... You would think it would show up in visual inspection of the drive belt ..... but I'm sure you would have made any corrections needed in that area ...... I just checked my Hydro-edge which I have kept at or near 17 psi for the entire time I had it on ( about 35,000 miles ) it is at the end of it's Safe useful life and will be changed this year ....... Mine is evenly worn across the tread area, I checked a few of the large water sipes with a micrometer and they had very little variance..... Here's the kicker tho , I run my belt AT 160 lbs... and it moves across the rear sprocket constantly ie. when I check it during a ride it is rarely in the same place when I look at it ...... and this is for straight operation , not backing up at any point ..... From what I know of your Cooper it is rated as a very high mileage tire...... I think 18-20 psi is a very good starting point ..... I hope my feedback helps you ...... Mike :thumbup:

I didn't get a chance to photograph my Altimax when it was removed. But at more than twice the mileage the center looked about like yours, and the rest of the tread was worn away much like that center rib... much more even wear (which should explain the double-mileage life I enjoyed). I weigh 170 and ryde solo probably 3/4 of the time, no trailer.
I ran it at the BRP psi of 28 for a very long time, until I learned on here that 17-18 was better. But I can't say at what point I lowered the psi. :dontknow:

So with the 1000"s of tire postings and comments, Spent many many hours going over 1000's of comments the average PSI are 18 to 20 rear and 17 to 19 fronts. Most posts averaged out to those numbers.
So with that, why are we still arguing this topic in heated detail?
I crunched a lot of numbers over the last week and found that most were very happy in the stated ranges and we getting the optimum millage and ride comfort.
This was also with different brands of tires that people are using. All came out the same.
Just to add another tidbit, My local dealer, BigO Tires, who, I have bought and has mouthed my tires, agrees with the above tire pressures due to the weight of a Spyder over a car.
The end
:yikes:

Tire psi Statistics
Well you went the extra mile in your statistic quest ( so to speak ). I'd like to add this to help define what you learned. Although I think the Kenda's are weak compared to Auto tires, I won't say that anyone NEEDS to get rid of them if they are on the front. If you have a well aligned ( ie Lazer ) front suspension the Kenda's can give decent mileage ( 22 to 28,000 avg. ), because each tire only supports half of what is on the rear tire ( approx. ) they wear ok. When they wear out and get replaced with an Auto tire the performance and mileage increase by quite a bit ( 35 to 45,000 avg. ) ..... The reason the front PSI numbers are in the upper range is because a lot of them are still Kenda's and Kenda's NEED the extra amount, in order to support the load ..... This isn't the case when Auto tires are used ( because they are stronger )...... Concerning the Rear tire numbers, the Kenda's wear out much, much quicker and most folks then switch to Auto tires which perform much better at the lower psi's you found ...... ...........As to why this topic is still Debated frequently, from my perspective it's all about SAFETY....Most folks would agree that if they see something BAD about to happen they intervene to prevent it if they can ...... I feel obligated ( I'm a former accident investigator ) to share my knowledge about tires............Mike :thumbup:

Because:
Some people are just stubborn.
Some people don't understand proper English.
But mostly because people ASSume too much and fail to include details with their statements/claims.
"You should run XX pounds of pressure in your tires." Is a totally invalid and probably misleading statement.
To make it anywhere close to valid or useful, you must also mention the model of bike, the brand and type of tire and the normal load.
EVEN if you have said a thousand times before what bike and tires you have. People have short memories.

Basically, you are being influenced by well-intending people on this forum, HOWEVER it is ALSO the victim of internet "group-think." The very vocal emoji-abusing tactics on this site over this one particular topic has been relentless. There are many that have their tire pressures higher than 15-20psi. They just don't say it here because it is just a hassle.
I've had a LOT of people private message me and come up to me at the Deadwood event that said that they, too, run higher pressures but don't want to get into some squabble with aggressive posters. James Thorne who put my wheels together and has done other work on my bike and many others runs higher PSI's on his Spyders, too. He is a highly educated engineer that services, repairs, and upgrades Spyders as another gig for him. Probably the last guy I'd listen to about car tires on Spyders is the kid at Big-O.
So, just because you've read it here countless times doesn't mean it is totally the way everyone goes. But, I'm glad you feel like you can call it: The End. I seriously doubt it will be, though.

Exactly, and I apologize that I wasn't clear about that in an earlier statement.
Car tires have wide ranges of characteristics: sidewall stiffness, pliability, rubber compound, tread, weight, etc., etc., So blanket statements about car tires on motorcycles can be VERY different. "Butt", don't say anything about how it "feels." You will get an earful of pounding emojis and grand statements of "butt science."
When I went through my own "discovery" of where my PSI's should be, I started low. It's a common statement here, so I started there. Low pressures did NOT feel right, and my spyder was SLUGGISH. However, the more I bumped up the psi's in my Yokohamas for my 2015 RT Limited, the more I loved riding my Spyder. I made a comment about it last year and was HAMMERED about it by a particular poster here. He was an absolute a-hole about it and we got into it. Next thing I know he is bragging about his cherished "sanctioned drag race" win. Fun times!
I did my diligence of testing what I could do with pressures in the upper 20's. I rode for miles, stopped and took heat signature readings (as suggested from tire experts here,) and also tried stopping distances on wet pavement. I have a very long driveway, about 1000 feet. Now, I wasn't getting up highway speed, but I got a good idea of what it could stop with. Honestly, I didn't see much difference with the PSI as much as how I approached the stopping, i.e., the technique. I went to a big parking lot during a rain storm and did the same thing. It was the same. So, I feel VERY safe at 26psi up front and 28 psi in the back.
I tried 15psi and laughed trying to just turn it in my driveway. Might was well be stuck in mud. No way any one will convince me that 14-15psi is correct for my Yoko's and the way I ride. But that is the group think here, and that's OK, just don't be an a-hole about it.
Now, General Altimax: I have no clue. Haven't run them. I have extra rims and I may just buy some to work through the same workout. I have the stock Kendas on them, and it is NIGHT and DAY difference with 26psi in my Yoko's.

From the National Highway and Transportation "Safety in Numbers." Volume 1, Issue 3, June 2013:
Underinflation leads to poor fuel economy, sluggish handling, longer stopping distances, and increased stress to tire components. Another concern is how heat affects tires. In the hot summer months, the high heat and hot roadways contribute to the breakdown of tires and a greater opportunity for tire failure.
Underinflation leads to poor fuel economy, sluggish handling, longer stopping distances, and increased stress to tire components. Another concern is how heat affects tires. In the hot summer months, the high heat and hot roadways contribute to the breakdown of tires and a greater opportunity for tire failure.
[*]Underinflated tires lead to sluggish handling, longer stopping distances, increased stress to tire components, and heat buildup. These in turn can lead to catastrophic failure of the tire, such as separation or blowout.
[*]Underinflation also decreases fuel economy. Proper inflation strikes the perfect balance of maximized safety and fuel economy – both related to the amount of surface contact between the tire and the road.
[*]A NHTSA study of tire inflation pressure and tire pressure monitoring systems (TPMS) showed that 12 percent of all passenger vehicles in the United States of model years 2004-2011 (with and without TPMS) have at least one tire underinflated by at least 25 percent (www-nrd.nhtsa. dot.gov/Pubs/811681.pdf).
[*]NHTSA reviewed data from the National Motor Vehicle Crash Causation Survey for tire-involvement before the crash occurred (www-nrd.nhtsa.dot. gov/Pubs/811617.pdf).
[*]About 9 percent of the estimated total crashes were "tire-related crashes." Some of the issues included tread separations, blowouts, bald tires, and underinflation.

From the NHTSA regarding motorcycle tires in a publication: "What's Your PSI?: Know your pressure levels and load limits."
Know Your Pressure Level and Load Limits
Know Your Pressure Level and Load Limits
- Become familiar with your motorcycle manufacturer's inflation guidelines. Look in your motorcycle owner's manual to find the right
PSI (pounds per square inch) of air pressure for your tires. Some bike manufacturers also list this formation on the bike itself. Common locations include the swing arm, front fork tubes, inside the trunk,
and under the seat. - Keep in mind that these recommendations are usually dependent upon the weight of you and your passenger, as well as any cargo. For instance, some manufacturers advise adding 3 or 4 PSI when carrying
a heavy load. Know your vehicle weight and load, and follow the PSI recommendations specific to your motorcycle. Failure to do so can result in adverse motorcycle handling (wobble and weave) or tire failure, or both.

From "Ultimate Motorcycling" Website. Motorcycle Tires: Top 10 Things to Know and Safety Tips. LINK HERE>
10. The old saying is that “the tire doesn’t carry the load—the air does.” The point there being that maintaining proper tire inflation is crucial to proper performance, tire service life and safety.
Under-inflated tires overheat, are more prone to blow-outs, sidewall failure and premature wear. Similarly, over-inflated tires may fail prematurely and wear improperly.

This is DOES mention OVERINFLATION, however, NOBODY knows when CAR tires on motorcycles are overinflated!

A couple of months ago I finally decided to get a General Altimax to replace my rear Kendra. I read a lot of the messages here and its the one I picked. I have been riding on the Kendra trying to get the last mileage out of it. Last week I took it to Dirty Deeds Powersports in Longview TX to have the tire changed. When I drove it home I noticed I was having the same problems yall described when the tire is overinflated, the ride was still a lot smoother. Next morning I checked tire pressure, it was 21 psi. I lowered it to 18 psi cold. My lady and I went out for a test drive.
HOLY SMOKES, SHAZAM !!!!!!!
(Clean version)
Talk about a drastic change in handling and smoothness of ride. Even my lady said it was more comfortable to ride, when hitting bumps in the road the spyder was less bouncy. We like to travel a lot of back roads for enjoyment, those roads are not in the best of shape. They were a lot smoother and it seemed the rear end did not sway nearly as much.
I dropped my lady off at her house and went for a ride one up to see if the same applied. The ride is AWESOME. Should have changed to the General Altimax along time ago.
SO
YES!!! The ride is SOOO much better then the Kendra.
YES !!!! I was amazed at the difference in handling between 21 psi and 18 psi.
Question? Is there that much difference in the Front end handling after switching to a car tires in the Front?
