After three of my six tires had failures within the first year I felt it was time to replace all of them. My RV came with 235x80x16 load range e tires and I replaced them with 235x85x16 load range G tires. They are about 1/2 inch taller than the originals and weigh about twice as much but with 14 belts that is to be expected. I got them at Discount Tire and they are branded Load Master. Paid about 1100 for the six including balancing and tax. Only time will tell if they are good tires but I am trusting in the integrity of Discount Tire to provide a good product.
Happy camping
