Does 4 Lug 4.80-8 and 4.80-12 Wheel/Tire Combo Use Same Wheel Bolt Pattern  

Updated 08/13/2025 | Published 03/31/2021

Question:

I have a boat trailer that has 4-80-8 4 lug wheel, can I put a 4-80-12 4 lug on the hub. I can move the fenders up if needed. I just need to know if the two as interchangeable.

Expert Reply:

If your 4.80-8 wheel/tire is mounted on a wheel with a 4 on 4 inch bolt pattern, then a 4.80-12 mounted on a wheel with a 4 on 4 inch bolt pattern such as # AM30620 would indeed fit. The bolt pattern is the same, the only thing that changes is the size of the tire and the diameter of the wheel.

Based on the previous 4.80-8/4.80-12 trailer wheel swap question, does it matter if the current 4.80-8 rims use Lug Bolts (4x4 pattern), for hub attachment instead of lug nuts? I thank you for your time.

@EdM The wheels you currently have are referred to as hub-centric. They partially depend on the pilot hole in the rim to provide some support. The replacement wheel you choose will need to have a pilot diameter equal to (just a tiny bit larger) than the diameter of the portion of the hub that extends through the pilot hole. I hope that helps explain it!
