I have Toyo M144s. We love them. But I would never mess with the sizes. If I was to alter sizes it would be on the rear where I have a Tag axle and the 4 drive tires. My rig takes 295s, so if I was to change size in the back it would be 275s H rated (for weight).

I DONíT KNOW THE KEY TO SUCCESS, BUT THE KEY TO FAILURE IS TRYING TO PLEASE EVERYBODY
