Common questions

How do I confirm 6 on 5.5?
Count six lugs. Measure from the center of one stud straight across to the center of the stud opposite it. If it reads 5.5 inches, it matches. 6-lug trailers are almost always 6 on 5.5.

Which tire goes on a 6 on 5.5 wheel?
On a 15x6, usually ST225/75R15. On a 16x6, ST235/80R16 or ST235/85R16. Read your current sidewall and match it.

Will a 6 on 5.5 truck wheel fit?
The pattern matches many Chevy and Toyota trucks, but truck wheels have a different offset and often a smaller center bore than a trailer hub needs. Use a trailer wheel.
