Hey Its time for me to get new tires. but I am stuck between two sizes. I do a lot of riding around local tracks where I have to do a lot of sliding and drifting. However, I've started to do some trail riding and I think that i might not be getting enough Clearance under my my Sprocket and Disk Brake. Right now Im running 18x9.50-8 in the back. I have to Chose between 18x10-8 which i know are great racing and drifting tires. or the 20x11-8 which I know will give me 2 more inches of Clearance in the back but I feel like the will not let me slide enough. Any tips? THANK YOU GUYS!
