Some of the liter riders at the gap go with 180 for a quicker turn in, that's about the only place I would even suggest running a 180 on a liter. Stick with the 190.

To illustrate the difference between the 180 / 190 ![]()

Nice find, here's the same type of illustration from this article.
Here's a stock 180 tire on an f4i' rim, notice how round it is ![]() Now compare that with the flattened look of a 190 put on the same rim. It looks wrong because it is wrong ![]() ![]() Quote:

pizdets post was good info-but since hes got a r1 it would be the opposite. a f4i rim is 5.5 inches, r1 is 6inches.

actually it wouldn't be the opposite... it'd just not be as pronounced a diffrence..

wasnt clear on that-not opposite effect- piz showed a 180 to 190 on a 5.5 rim, o.p. asked about goin 190 to 180 on a 6inch rim. thats what i meant.
as far as actual effect i have no clue- i always thought if i put a 180 on a 6in rim, it would have more straightline contact patch, and if you squeezed a 190 on a 5.5in rim, you would have less straightline contact, and more contact when leaned over. pizdets pic seems to show the opposite |

your right... a wider tire on a narrow rim will be more curved. (done this many times with my truck tires as it makes the beads harder to blow out on the trail when I run reduced pressure)
I just looked at the pics... yeah the 190 will be more curved the 180 will be flatter to fit in the same width rim |

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