the first # is the tire hiegth from ground to top of tire. the second is the width. The third & most important is the rim size this # must be 9. hiegth is not really tht important except for ground clearance. The smaller the tire hiegth
the more rpms that means faster. the taller means less rpm but 1 or 2 inches wont make much differance. The width remember wider is better. I am running 22x12.5x9

 

Im sure of what im getting now.. Thankyou everyone. You made my decision easier.
