• 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.

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.

No fenders and tire sizes

MAYBE THIS WILL HELP

So IF you go by the tire comparison chart, the yokohama is going to be 0.4in shorter but 0.78in wider?

JCTHORNE in post # 8 above has a good explaination.......................I don't know the exact numbers ....the above ones you give could be correct......I do know the size ( REVS per mile ) is very close to Stock OEM.................The YOKO just has a much wider footprint in relation to it's overall width, which is only slightly wider than Stock :thumbup:

Dan I'm not positive on this buuuuut.....I think they measure the circumference of the center of the tire tread inflated ( to what PSI I don't know ).....As far as DEPTH of tread goes as a tire wears it's going to get smaller this is the same for all tires. I don't think they give a REVS per mile based on tire with " no tread " ?????.....And I'm MOVING .....ASAP:roflblack::roflblack::roflblack:

MOVING....??? when i made the decision to relo from FL to SoCar, it took me all of 2 minitz to decide......
com'mon man.... JUST DO IT..... :yes: after this winter, u need to GET YOUR WHEELS TURN'n.....
we need to break-bread pal..... :gaah: :bbq: :cheers:
 
I didn't see this posted - why are you looking for bigger/taller tires?

I am guessing you are staying with 14" wheels, just trying to find biggest tires? I don't know if you were looking into trying to mod the bike to go with 15" tires/wheels. If you did this, you could upgrade the brakes to use the bigger (270mm) brake discs.

Don't want to start any arguments here, but in your opinion, why not the Yokohama S Drive?
Click to expand...

my opinion is based on 20,000 miles of use with the KUMHO's.....
i've rolled these from SC to UT n back, in all types of road conditions, with ZERO negatives....
the choice is yours, i'm just try'n 2 give u some info... good luck.... let us know the results of your choice.... :popcorn:

Not looking to necessarily go bigger. Original post was just wondering what my additional options were since I dont have fenders and without messing up my speedo

Well thanks for the input. I know I should not be going by looks but I do really like the S drives. I ultimately want something that isnt going to mess with the speedo. It seems though with any of these options, it wont be a problem?

So I have been doing a lot of research on tire sizes that will work with stock fenders. My fenders have been sleeping soundly in the garage for the past 2 yrs with no plan to put them back on. I am not saying I want to go as big as I can since I don't have fenders but what is a smart way to approach this? I am scared of getting into trouble with the nanny too. I have found a few threads that have said that no one has reported issues with going to a bigger size and that going a step or two up will actually make the speedo a bit more accurate? Right now I am looking at the Kumho Ecsta AST (stock size) for the back and Falken Ziex ZE-512 for the front (185/60R14) Thoughts?

The change in tire size that results in the speedo being more accurate is with the rear tire, not the front. See this thread I started for more information:

The math was OK, Thanks Bob

Thank-you for recognizing that my math was not at fault. Considering I had an Associates Degree in Mechanical Engineering I'm pretty sure about it. I had done all of that math when I changed brands of tires on my last motorcycle. It turned out that the tire circumference of the new tire was only 2% less than that of the OEM tire, however since this was the rear tire and had to do with the odometer reading I was actually only covering 98 miles when my odometer indicated 100. That meant I was only covering 980 miles for every 1000 indicated or 9800 for every 10,000 miles. The error gets pretty big over long distances.

Just keep in mind, the longer the tread life, the harder the compound with LESS traction. You've got to make a decision on which you need most, tires that'll roll forever or tires that'll grip in the curves.

Most of my riding is in the mountains, so while I'd love 100,000 miles my priority is gripping the curves. How would I figure out which tires best accomplish that -- any recommendations?
 
MAYBE NOT

Den, if you are using a chart for your calculations that chart leaves out a very important fact..........The real circumference of EVERY size of tire varies from brand to brand. They are all made from different molds to meet the manufacturers tread design......Why is this such a difficult concept to understand ????????? ....Tire a, and tire b, are listed as the same size,,,,,However their circumference is different because they were made by different company's

Since your in the mountains (curves) I too want the handling on the curves and with the responses/recommendations I have seen I will be going with the Kumho Ecsta AST on the rear (stock size) and the Yokohama S Drive on the front 185/55R14

This is a good choice, however it would be my second one. Since my son is in the tire business I can get any tire I want and since I look at info from a different view than the consumer and am only looking at performance. Things I look at are, the ability to displace water. This is important to me cause I have chosen a wider tire for performance (185/60/14 and a wider tire will hydroplane quicker. Next is wet traction, dry traction, and then something that most overlook is the weight of the tire, this affects performance and mpg. Speed rating is not important to me as long as it exceeds 120 mph.

So what is your first option? I never ride in the rain unless I get caught in it and in that case I go hide under something :)
 
How do you find your tires and order them?

I'm also curious to hear what your first choice would be, but I DO ride in the rain regularly in the spring/summer -- it's Colorado and the mountains... you can expect a rain shower to pass through most afternoons. In the winter there is snow melt runoff going across the roads so they're often wet, and sometimes icy depending on the temperature, steepness of the canyon, side of the road that the river runs, time of day, wind speed...

Separate question: What process do you use to get alternative tires? I went through that list that was posted in a previous post looking for any tires in the right size (for the front) and kept getting "there are no tires available in your size" with all the brands listed in most of the US tire companies (UK seems to have a lot available but I don't feel like paying the exchange rate). I went to all of the companies that people have included as links. Either they didn't have the 165/65r14 available at all or as soon as I put in my zip code they dropped off the list.

I liked the goodyear ultragrip 7 tires but no matter where I searched, kept getting a message saying they weren't available in that size. I haven't made any phone calls yet to see if I can custom order them, is that what needs to happen?. The whole search was a little disheartening. I guess I'm too used to instant shopping gratification with all my other purchases. I make a decision on what product I want, I search for it, it's available at a price I'm willing to pay and I order it. So far I've had no luck with tires...
