Question:
I have a 1996 magic tilt boat trailer that has 4.80-12 tires on it currently with 4 on 4 bolt pattern was going to move up to the 13inch for better ride, was planning on buying the new rim tire package and was wondering how big of a hight width difference I would be looking at upgrading to the 175/80/13 thank you

Expert Reply:
A 4.80-12 trailer tire and wheel such as the Kenda # AM30630, when inflated will measure 20.7 inches in diameter and have a width of 4.9 inches.
A 175/80-13 trailer tire and wheel will measure 24 inches in diameter and have a width of 6.6 inches so you do need to measure to ensure you have the necessary clearance.
A great option for a 175/80-13 trailer tire and wheel with a 4 on 4" bolt pattern is the Loadstar # AM3S130 which has a galvanized wheel or the Loadstar # AM3S120 which has a white wheel. Both of these have a load range of C with a capacity of 1,360 lbs when inflated to the max 50 psi.
I have added links to video reviews of these wheel and tire combos for you to check out as well.
