8 vs. 9 inch rear
8 vs. 9 inch rear
Looking for some opinions. I have 9x9 Hipers right now on my rear, but Im thinking about doing more MXing this season, so Im wondering if it would be worth getting new 8 inch rear rims to run 18 inch tires on. I have also seen many members on here that are running 9 inch rear rims with 18 inch tires. It would obviously be easier if I could just keep the 9's I have now and put smaller tires on those, but if it's a big disadvantage running the larger rim, I might consider switching. What do you guys think?

since the rim is smaller it would have to affect it somehow wouldn't it derno....?...i realize that a tire 1 size can fit either a 8 or 9 but going smaller( rim wise) wouldn't it in return spin faster regardless of the tire size...?..or am i not understanding this correctly...?....
You are correct that it should spin faster due to less rotating mass, and there would be more sidewall flex too. Flex would make the suspension seems better. You know more air in the tire and all.
What I was getting at is if the Tire outer dimensions are the same on both rims then the final top speed would be no different. 18" is 18"
