I am building up a 24” full suspension all mountain rig for my son. I have one decent 24” tire from one of the euro sites that i bought a couple years ago (cant recall the brand but its 2.5” and labeled for back). Anything domestic i can pick up quickly? Using a 26” fork up front so no worries on clearance (the 2.5 i have fit the fork just fine). What are some options and where can i get one relatively quickly?
