Great Tires!
Great set of trailer tires! Relatively priced and very fast delivery. The only negative thing about the purchase is the $4.00 tire disposal fee that was added to the transaction. I am disposing of the old tires.... I can only assume that this just another one of the Govt regulations we are all chocking on these days.
Verified Purchase
Great tire for my needs
I bought these tires for our boat. They are great tires for our purpose. We are 25 miles from the lake and the boat trailer sits loaded for about 8 months at a time. Less expensive and a good tire.
Walmart couldn't install, but ok otherwise
Walmare TLE was unable to install these, as the 10-ply tires were too stiff to seat the bead on the rim by any means authorized by Walmart. Had to have them installed by a professional. Otherwise they seem to be okay tires - we'll see how they do when I take my popup on vacation!
