Load index

Just bought a pair of goodyear f1 but just relised ive ordered these in xl load by mistake , will it make a difference ,thanks
 
As long as you have the correct speed rating and not lower, you'll be fine. All XL ones are is (extra load) I belive it's just the walls are more reinforced, so you'll have a stiffer ride.

They're made for cars that usually carry a bit more weight around.

someone will clarify this when they reply
