180 or 190

t-homo · 05-07-2008, 05:53 PM

From what it sounds like, most people seem to run 180 back tires right? On the 2000 R1, a 190 came stock, and that is what is on it now. Why the difference, does it change much, etc?

190 refers to the rear tire width in mm's. A 190 is slightly wider than a 180. I'd say keep the 190. A 180 will give you quicker handling at the expense of some traction, you need traction more than handling on that bike. At least for now.

The explanation of the rest of the code:

190/50/ZR17

190 is tire width,
50 is aspect ratio at max lean
ZR is speed rating
17 is rim size.

Yeah, i knew what it meant as far as size. Just wondering if one was better than the other or what.

I'd stick with what came stock, in this case the 190.

fair enough. After looking at my buell's 120/60s16, That thing is absolutely massive.

I figured you did, I just wanted to illustrate why I thought a 190 would be better. Rather than just posting "Keep the 190"

actually because the 180 is going on a wider rim it will flatten it out and increase the contact patch for straight line... but reduce the profile and give it reduce handeling... or in theory it should...

Interesting conversaton and comparisons and all BUT since a 190/50 came on my R1 and a 180/55 came on my R6 that's what will stay on them...I'll just trust Yamaha got it right.
