Can I Use a Trailer Wheel with a Different Size Pilot Diameter

Updated 07/05/2010 | Published 07/02/2010

Question:

I want to replace 4.80x12 tires and rims with a size bigger wheel and tire. Current wheel is a 5 on 4-1/2 bolt pattern with 2-3/4 hub, 20 over all diameter. The following item shows a 3.19 pilot. Is this the same as the hub? Does that matter as long as the bolt pattern matches and the pilot is larger than the one being replaced? Thank you, RE Your tire............. Rim dimensions: 13 diameter x 4-1/2 wide Bolt pattern: 5 on 4-1/2 Wheel bolt size: 1/2-20 Pilot diameter: 3.19 Tire size: ST175/80D13 Section width: 6.6 Outer diameter: 24 Capacity: Load range: D Ply rating: 8

The only time the pilot diameter will matter is if the wheel is hub piloted (wheel is centered by the hub) or if the diameter is too small. So you can use a wheel that has a larger pilot diameter as long as it is stud piloted (centered by the wheel studs). You will be able to use the Loadstar ST175/80D13 Bias Trailer Tire, # AM31233.

The Loadstar tire will be about 2 inches wider than your existing tire so you will need to make sure the trailer can accept a tire this size.
