I went to a tire shop that specializes in motorhome tire replacement. The salesperson said the Toyo tires for my coach were no longer available. I was told that Goodyear made a special tire for coaches in the 12R22.5 size (G149RSA) that would replace the original Toyos. The only difference is the Goodyear tires have less rubber thickness in the tread area, making for a lighter-weight tire and better ride. The Goodyear tire is also 1/2 inch smaller in rolling diameter than the Toyo tires of the same size. This concerns me. The Allison transmission computer is programed for tires of a larger circumference. Will these smaller tires have an adverse effect on fuel economy, performance, engine and transmission wear?
