I am in the market for tires. I have the Mickey Thompson Sportsman S/T tires and I like the way they look but they just did not have the grip I was looking for. I spoke with tech support at Mickey Thompson and was told there would not be a significant increase in grip going from the Sportsman S/T to the Sportsman S/R. The Mickey Thompson Sportsman S/T, Cooper Cobras and the BFG Radial T/A, all have a treadwear rating of 400 to 440. I doubt any of the tires in this range have significant advantage over the others but that is just my opinion. I could not find the treadwear rating for the Sportsman S/R tires, but from reading about them, most say they are better than the BFGs or the Sportsman S/Ts they ran previously.
I am looking at running drag radials on all 4 corners. Specifically Nitto NT555R 275/50R15 on the rear and Mickey Thompson ET Street S/S 235/60R15 on the front. A couple things to note. I do not track my car or drive near the limits in cornering and I am not worried about the paint because I completely lack paint at this point in time. I do not street race but when I step on the gas, I want to go and not spin the tires and I want to stop better when the brakes are applied. I do not drive in the rain and it rarely gets below 40 here in San Antonio, Texas. Besides much shorter life and poor performance in the cold (sub 40*) and rain, are there any pitfalls to running drag radials on all 4 corners for every day cruising? The new dodge Demon sports drag radials on all 4 corners from the factory, just sayin'.
