Here are a few industry guidelines to help you make your replacement tire selection.

"Never choose a tire that is smaller in size or has less load-carrying capacity than the tire that came with the vehicle."

"Tires should always be replaced with the same size designation — or approved options — as recommended by the vehicle manufacturer."

"The correct tire size designated for your vehicle should always be verified with the information in your vehicle owner’s manual or on the tire information sticker."

With RV trailer tires it’s very important to gain load capacity reserves with your replacements. The very basic industry standard is to never use less load capacity then the OE tires provided. Why waste the money if you’re not going to take advantage of readily available load capacity reserves? You know, steel cased tires “zipper” rupture. If you ever have a chance, take a look at the diameter size of the steel cables used in the steel cased tire’s sidewalls. You won’t want to excessively flex them under normal circumstances.

p.s. Quotations are from a Michelin PDF.
