Thread: 190 vs. 180 rear tire......

Generally what you say has been true in mine and others expereinces. What kind of riding (street/track) do you do, and what is your suspension situation?

A 180/55 and a 190/50 are very close to the same diameter on the brands I checked.

I considered doing this on the Triumph 955 Daytona I had. The local guy I buy tires from (a racer) said that it depends on rim width whether it will be a benefit or not. Putting a norrow tire on a rim wider than what it is designed for will cause the tire's cross section profile to be distorted from what it was engineered for.

Made sense to me, I went with a 190. Maybe others have more experience with this.

Makes sense to me also. With a bone stock suspension and with my riding strictly street and local twisties, I think I'll stay with the 190. Thanks guys.

I had 180/55 on my 954 because a couple tire guys convinced me that the 180 turns so much quicker and now went back to a 190/55 using the Dunlop 209s...

I will never use a 180 on that bike again.....

190 is the way to go and on the 929..... you would have to put a 300 on it before it turned in to a corner slow.
