The are cheaper for a reason. Harder tire compound. On 600rwhp in seond on ET streets i have a problem hooking up in second from a roll. The warmer weather helps, colder weather good luck.

At that kind of power level and beyond, really 15" is the best option. I have had really good luck with the 325/45/17 m&h drag radials however.
From what I have used, the Mickey Thompson ET Street R in 325/50/15 is an absolute monster tire. I love it.
I also had really good luck with the same size in the M&H. The car would dead hook 3rd at 60mph with a 15psi brake boost, making 915 wheel.
LOTS of people rave over the 275/60/15 ET Street Pro, but I have never used them.
I have a 94-98 sra which uses the same spacing as an irs. I use 15x10 with 6.5 backspace.Are you an SRA car? If IRS what back spacing did you use to fit 325/50/15s in there? I mocked up a buddies and they were not fitting but his back spacing was for the SRA he swapped in so we couldn't get a proper test.
Even my 295/55/15s needed some fender rolling and things are tight.
Anyone using a 325 non drag radial and able to hook at these power levels?
