Tire question:
I’m interested in purchasing an M923 or M923-A1. The M923 comes with 11:00-R20 tires, and the M923-A1 comes with 14:00 R20 tires. I understand that aftermarket gear ratios for Rockwell Axles are not readily available – thus to obtain faster cruising speeds, folks often install taller tires.
How large do people normally go with the duals, and also with the super-singles (A1 & A2)?
How much do replacement tires cost? I’m assuming that replacement tires should meet or exceed the factory ratings. However I’m embarrassed to say that I have no idea how commercial truck tires are rated, or even where to purchase them.
