Replacing 8.75R16.5 Tires on Dual Axle Trailer

Question

Question:

Hi, Im looking for options to upgrade the tires on my dual axel trailer. I want to update all 4 tires plus add a spare which would need a galvanized wheel. Current tires are 8.75R16.5 on 6-5.5inch bolt circle. Thanks,

There is a solution for you, though we only have light truck tires that will fit a 16.5 inch diameter wheel. Instead, you would need to replace your wheels with something that supports a more common tire size. I recommend the Kenda # AM32666, which has a galvanized steel wheel that fits on a 6 on 5-1/2 inch bolt pattern and uses ST225/75R15 tires that have a D load range.
