Question:

Im looking to replace my 4.80-12 tires with size 13inch tires. Now I know I need new wheels with tires. I was looking through your items but cant seem to find the rims with a 2.5inch pilot diameter. They are a 4 bolt by 4inch rim. Please Help.

At this time we do not have a 13 inch, 4 on 4 rim with a 2.5 inch diameter pilot hole but I may have a couple of options available for you.

Finding a wheel with a matching pilot diameter is only a concern if you have hubs that are hub-centric. This type of hub uses the hub bore in order to center the wheel. This is what makes matching the pilot hole diameter extremely important. Wheel bolts are typically used instead of lug nuts to attach the wheel on these style hubs. This type is more commonly found on import vehicles and are not very common on trailers.

If you a have lug-centric hubs they will use lug nuts in order to center the wheel on the hub. Matching the pilot hole size would not be a must because in this case, it is not used to center the wheel. A larger size pilot hole could be used and would not effect mounting your wheel.

I have a couple of recommendations for you if you have the lug-centric hubs. We offer a Loadstar ST175/80D13 Bias Tire with 13 inch Wheel, # AM3S030. This tire has a ply rating of 4 and a 1,100 pound maximum load rating at 35 psi. Another option would be the # AM3S120. The tire that comes with this wheel has a ply rating of 6 and a 1,360 pound maximum load at 50 psi. The wheels for both feature a 4 on 4 bolt pattern with a pilot hole diameter of 2.65 inches. Always keep in mind, increasing the tire size or weight capacity will not increase the weight capacity of the axle.
