Trailer Wheels & Tires
A trailer tire is not a car tire. Look for "ST" (Special Trailer) at the start of the size — the ST175/80R13 listed here is the common size on single-axle snowmobile, ATV and small motorcycle trailers — and match the load range printed on your current sidewall (the 205/65-10 here is a load range C tire). A passenger tire or a lower load range on a trailer is a common cause of highway sidewall blowouts.
To replace a wheel, match three things: rim diameter (the galvanized Atw wheel here is a 10-inch), the bolt pattern (this one is 4-hole), and the bore. Galvanized steel is the right pick for a trailer that sees road salt or boat ramps, which is most snowmobile trailers.
Grease seals are the part most people forget until a hub slings grease across the wheel. The Universal Group seals listed here are sized by outside diameter — 1.983" and 2.565" — so measure the old seal (or the hub bore) before ordering; the number stamped on the old seal is the quickest check. Repack the bearings while the hub is apart.
