Hisham & other PT 42 & 43 owners. A ? about your tire size

[Pete Masterson]

I have 12R22.5 tires in all 8 positions. THe wheels on my coach are
8.5" wide.

315's offer an interesting upgrade possibility -- but the major
concern is spacing between the tires on the dual axle. If the tires
rub (at all) there is a significantly greater chance of a premature
failure.

The previous owner selected Toyo tires. Toyo has since quit offering
RV tires (but their "bus" tires work just fine). Apparently, some RV
manufacturers, using the Toyo tires had overloaded them, causing wear
and blowout problems. (But the garbage came back to haunt Toyo, not
the mfg. where the real responsibility lay.)

I recently priced some Sumitomo tires at J&O Tire in Richmond, CA.
Their price was competitive with Les Schawab who provided a
replacement for one tire that had been ruined by misalignment (and
wear) in the front end. (My tag axle tires are looking just a bit
rough from wear caused by the inescapable dragging they encounter.)
