Let's say Holeshot XCR rear tire with a .190 aluminum wheel. Would it weigh less with a 8", 9", or 10" wheel?

the 8" would weigh less because its a smaller rim. less mass

Less aluminum, but more rubber on the tire. So is that still true?

I'd guess the 10 inch wheel would be lightest. But you are going to get too many dented rims. The 8 inch wheels would get fewer dents but at the cost of sidewall flex. That's why most XC racers get 9 inch wheels. Regardless of size, with regular .190 wheels, you are going to get a lot of dented rims. When I ran Douglas .190 (red label) rims, I had to replace the rims more often than tires. I now have some Douglas Ultimate rims with the rolled edge and they have held up great. They are over a year old and are still round. If you still have your stock rims use them. They are lighter than the .190s and since they have a rolled edge they are stronger.

the aluminum is lighter than the rubber. the bigger the rim the more weight you will save because you'll have less rubber.

I was wondering the same thing... I am going with the bigger rim though, Your not adding a whole bunch of aluminium either... Can anyone get specs? weights?

your not going to notice the weight difference inany of the set ups, so get the 9 inch wheel for the best perfomance. the sidewall is tall enough for a smooth ride, and short enough for corners.

yup, and if you need a replacement or wanna sell the odd sizes, not gonna happen as easy as with the 9"
