Tires???

What tires do you think i should run for XC racing i was thinkin
22 11 10 razer 2s on the front and 20 11 9 razer 1s on the back any input would be great

I run 20" on the front and 19.5" on the rear. I am getting 20"s on the rear. Thats the actual size not the size they say

so i should run the same size front and back

for the front you want a 22x7x10 or the 21x7x10 in the Razr 2 and the if you are racing xc in pa you might look at running the razr 2 for the rear also the reason most people run the razr 1 in the rear is due to weight but if you don't want to get stuck and aren't pro fast I would run the razr 2.

I'm not sure, I will be running exactly 20" fronts and 20"rears. The extra 0.5" should help me a tiny little bit over the ruts and trees. My brothers razr fronts say 21" but they are 22" and his rear are correct with being 20". My front tires say 21" but are 20" and my rear say 20" but are 19.5". Razr rears run the exact size they are but the front are different. I personally like having a little bit smaller tires than my brother in the front because it has less body roll and just seems to have a better center of gravity. I like my Kingstire fronts better than the Razr because they have a higher more defined center ridgeline which is better for sugar sand which is what I mostly ride in. I'm not sure the type of riding you are doing so idk about sizes.

I race in Pa and here are the tires setups I have ran.

Stock 450r Front and Rear

GNCC fronts 22" fronts and 20" Klaw Rears

GNCC fronts 22" and 20" Irazr rear

GNCC fronts 22" and 22" XCT rears

ITP XC fronts 22" and ITP XC rears 22"

Kenda Klaw fronts 22" and 21" Knarly rears.

Out of all of those setups and with all of them being used in PA, my favorite setup is the klaw fronts and knarly rears. You just cant beat that setup. Plus in PA we have tons of rocks,so if you even try to run a tire under 20" (most under 20" are only 4 or 2 ply) you will not be finishing the race on 4 good tires.
