So between cutting a sidewall in one of the tow max tires, a slow leak in another (same trip) and getting low on tread it was time for new tires. The wife and I decided we would go with "big boy" truck tires. 16 ply steel sidewall tires are really stout. We had to replace the old rims with new 17.5" rims as well. I can only hope that there will be many of care free miles ahead of us. Here are some before and after photos. We went with the all silver rims because we thought it would look better with the blue / silver cyclone.
