I have beadlocks and Irok bias ply tires. Not a good combo for street, plus they are my wheeling setup. I will get a 15in wheel, but need a decent tire for driving on the street. The 38.5 TSL's will go fast probably. This is not an everyday driver, but it's a blast to drive around town. It's nice to be able to drive to the car wash. I haven't looked into 37-39 in tires, and not sure what tires are out there that aren't real agressive. A 39 will be closer but I have 16/38.5/15 now, on a 15x10 wheel, and something like 3bs.
