Everyone will have different opinions I had a set of M/T 33X15X17 had 175 passes on them still lots of thread left but they went away 25 passes before that. I would have to due a longer burn out just to get the car to hook consistently. Put on a set of Goodyear 33X15X15 stiff side walls and the reaction time of the car was much quicker had to add .019 to the box. But I due miss the 17” width next set will be 33X15X17 make it a better bracket car on full out passes. Just a side note the M/T coming of the stop was a hand full the GY handle perfect off the stop. But maybe the side walls were dead on the M/T long before that.
