Tires General Altimax Opservation

[DaveZinAz]

Not a tire for the Spyder but it is Science

First, as a newbie, I find this whole conversation funny as heck. Both sides convinced they are on the correct side.
I will be the first to admit I have not done any testing nor have I been to any school, however, I have done a lot of related research.

My other 2 vehicles are a Ram 2500 and a Jeep Wrangler. This is mentioned because I run non standard tires on both and have had to determine the correct tire pressures to run. The federally mandated placard does not apply to my scenario.
I assume (I know what that means) that the tire manufactures have the very elusive science everybody seems to be interested in.

The following links have been helpful in helping me to determine what tire pressures to run in the TOYO tires I run on the Ram and Jeep based on the loads I expect the tires to carry.

https://www.toyotires.com/tires-101/tire-load-and-inflation-tables

This is a link to the rather long PDF showing different pressures for the same tires based on loads they expect the tire to carry.

https://www.toyotires.com/media/2125/application_of_load_inflation_tables_20170203.pdf

I don't know how this fits into this discussion specifically except that many people have mentioned science and facts and I think this is about as close as an example we are going to find for determining proper pressures. As I said, these don't pertain to the tires in question. A person would have to find similar data from the manufacture for the tire they intend to use.

It would appear to me that without the correct load-inflation table for the specific tire you are planning on mounting AND an accurate weight/load for the tire/axle in question, you are just guessing on the correct pressure.

If I am totally off base here, chalk it up to being a newbie...

Consensus isn't 'proof'

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.

I need to chime in, for the record. I also, am one who tried the soft VS. The Higher inflations, on both fronts and rears. On my 2012 RT, the original 13 psi BRP recommendation in the front Kendras were so squishy, it felt like I was rinning with flat tires on the corners. The 28 psi in the rear seemed OK, and I stuck with it, until I switched to Khumos, but I increased the fronts to 20 psi, raising and testing 2 psi increases until 20 psi FEELS the best for me, for handling, and cornering. As for lowering the rear below 20 psi, even riding one up, with the Khumo which I have used 5 of, again, the Spyder felt very sluggish, gas mileage decreased, and I ended up raising to 30 psi in the rear, and keeping it that way along with 20 psi in my fronts, and have continued the same with my 2016 RT. I think tire and Oil discussions are as subjctional as discussing Politics and Religion.

I've got to admit that you're correct...

Consensus is not the same as overwhelming evidence either.

The human race is overall pretty stupid.
I think we are doomed to die frozen in the dark........from events of our own making.

I look at your post as informative. You took the time to discover what you liked and didn't like. You took the time to discover what you think is good for you! Plus!! You took the time to give INPUT about it! Yes! That's how a productive forum works!

However, when I, and others, said similar things we get lambasted! Referred as "butt science!" You are not allowed to say "feel" here.

You see, I don't give a flip what others put their tires at. I really don't, but we are not allowed on this forum to say, " Hey... I did this, and that, and found that I liked my tires at ... psi." Nope! All because of the group think and insults that happens here. So, I'd caution you on reporting findings like you have done.

It wouldn't be much different than the number of people that have approached me on this forum, Facebook, and in person that have their tires at different pressures than the group think here.

Sooooooooooooooooooo tired of this line of rehtoric

Give it a rest - What I find so interesting is how much YOU go on and on about diversity of opinions etc. and how you've been personally attacked for YOUR views ( this is a LIE ) YOU feel YOUR freedoms are being violated ...... But then YOU don't respect the rights of others here to have a differing view. YOU believe YOUR rights are the only ones that matter. Todd if you think others on this Forum don't/can't see You for the Hypocrite that YOU are ..... I TRUELY feel sorry for you. Sad so sad ........If EVERYONE can't have the SAME rights than NO one is going to have any rights...................Mike :thumbup:

Altimax Rear; Continental Contipro Front

I run Altimax on the rear at 25 lbs and now have approx. 21,000 and the tread looks like new. I run Continental Contipros on the front at 20 lbs and now have approx. 21,000 and the tread looks like new. I should get at least another 21,000 on both the rear and fronts. (These tires were put on both my wife's 2015 RT LTD and my 2013 ST LTD at the same time by myself with pretty much the same mileage -- we do most riding together, as on two bikes). Ride safely everyone!

AND......YOU constantly complaining about it just keeps the pot boiling......for no good purpose.

Has the forum administration given you any official warnings yet ?
I suspect not.
But if you keep it up, they might.

Chill, please.

(I do agree with most of what you are saying.......but one needs to know when to let go.)

I shouldn't complain when someone is personally attacking me? See the post above yours. On the thread that was just shut down, he literally compared his knowledge base as to what Einstein's level of knowledge was to the theory of relativity. So, we should just do what he says. That there is just too much knowledge that he's accumulated and that we weren't smart enough to even comprehend it. Seriously?

He challenged me with his "sanctioned drag race" big win months ago. I responded that I'd race him.

He asserts that claims of higher tire pressures are "butt science," (who talks like this??) yet he has no science to prove that lower pressures are better, nor does he even know what a safe RANGE of tire pressures are. Because there is no science for car tires on motorcycles.

Yet, he can rant and ridicule, but I'm not allowed to call him on it? I shouldn't say anything because the groupthink here is that low pressure is the best, and you will be ridiculed if you say otherwise for what your OWN personal experiences are? Is that the flavor here?

Do you also know that he made disparaging remarks on a Four Sale item that I had up? Lamont had to delete it. He even apologized to me that crap like that happens here, and something else that I will not say publicly. You ask that the forum administration has given me any official warning? Seriously? You think he should not be toned down, or "chilled out?"

LOL. Not once have I stated that lowered tire pressures are bad, but when I've stated that I've found differently for my own riding style and desires, I get your vitriol from YOU, nobody else. ANYONE that has read this forum for the last year knows this. They just ain't sayin' it.

My "rights?" Huh? I've just pointed out that there is no science regarding car tires on motorcycles, and nobody (including ex-LEO's) knows the range of safety for tire pressures. When I've posted proclamations from respected and government agencies regarding underinflated tire pressures, that gets thrown out.

I literally can't stop laughing about this.

You are conflating two issues: tire and rim compatibility, and tire pressures.
Car tires on motorcycles wheels is probably not the best idea... The Dark-Siders can flame me for saying that!
But since the Spyder uses automotive style wheels: it's not a problem...

Feel free to go back to fighting over tire pressures now... :thumbup:

I see what you're saying. I was being too simplistic. Let me clarify: there is no science for car tires on motorcycles that also use car beaded rims. Better?

TIRES

Just to get back on track, I received my General Altimax tire yesterday from Discount Tire Direct. Size is 215/60/R15. Looking forward to having it mounted as soon as my Michelin Hydroedge wears out! I use 20 psi and am very happy.

 

[tehrlich]

And... just like in the thread that was shut down, I will apologize for being a part of this tire pressure issue. I know that people are tired of it. Oh my gosh... me too. So, sorry about that. No moderator made me say this. I just know it is exhausting and going no where.


I'm still riding my Spyder the way I like it at 26 psi up front and 28 on the back for my Yokohamas. I've done my due diligence to discover this with these particular tires.



Done.

The pressure of this thread gave me a pain in the tire gauge.:joke:

If one of you can take the high road, there's less chance of a collision.

I'm well aware your intelligence level is off the charts ..... so how come you haven't figured out that I don't care what psi's you are using. If you told us that you were going to go with 40 -50 -60 psi, I wouldn't try to deter you from doing so ..... My concern is the Newbie's on this Forum who are seeking advice on what they should be using for Tires and/or tire pressures.........It's really that simple ............ You and Easy Rider and tehrlic are always asking me to PROVE what I say is true ... ( the fact that I was a Court certified expert seems to have no meaning for any of you ) How about you Naysayers produce some PROOF that " over-inflating " car tires ( based on the weight of the vehicle )for use on a Spyder is better ????? ....... I'll await that info ....... Mike :thumbup:

With some regularity you refer to having received specialized training as a former law enforcement officer, and as having testified in Court as an expert. How about posting your CV, and providing the particulars with respect to your expert testimony (jurisdiction; scope of testimony; number of times, dates, and so forth)?
