Hello everyone, just wanted to ask a quick tire question. I have 18" rims front and rear, but I need to replace the old 2007 tires that are on them currently, which are 90/90-18 front and 110/90-18 rear. From what I've been reading from other posts on the forum is that the stock rear is 120/90, but I'm curious when someone would use a smaller tire size, as most people usually go bigger. Should I buy another 110/90 or go back to stock 120/90? Thanks!
