For the rear i buy Kumho ps91 275-35/19, they have a tire wear of 240. They are what i set the street tire, no posi. unit
record with. 12.008@ 114, My 60' was 1.59. These tires stick like glue, very few srt-6's can spin them.
For the front i get Kumho but this time the tread wear is in the 500's for long wear.
