Right now I have a set of 8" ITP beadlocks with 18" tires. Should I buy a new set of 9" DWT beadlocks and put on 20" tires? I know 18" tires are known for motocross which I do ride but I also ride trails alot and sometimes I notice the 1" less ground clearance of the swingarm when going over rough terrain and hitting and dragging it. I really am at a toss up because I ride mx alot too. All input appreciated!
