Jerry,
I found the Bridgestone tires (R 250) to be an excellent choice for the drive axle. I replaced all of my tires with Brigestone 5 years ago and the drivers preformed better than the steer axle. I just replaced the steer tires due to wear, but as a fulltimer I probably drive more than you. However the drivers still look excellent and I plan to run them another 2 years.
