tirerack.com 315/35 htr z 17 $107 hell of a deal if your looking for an inexpensive tire

 

thats where i got mine from cause im putting slicks on 15' rims so i dont need alot for racing there just street tires

 

I know someone has them on a Firebird with 380rwhp/370rwtq. He can't get traction for anything. They don't last long either. Also, they aren't very wide compared to other tires of the same size. I know everyone's going to say that if they're the same size they should be the same width, but they aren't. They amount of tread touching the ground is the same as his front tires which are 275 Kumho Ecsta 712's. You get what you pay for.

 

I have them on my Cobra.

They are worth the money but don't expect them to perform like an 160 or 180 dollar tire.

 

I have the HTRZ II's in 275/40/17 on all corners. It is just like everyone else said. They are a great tire for the money. They last longer than DR's, are not extremely loud, and drive pretty well. Traction at the track is impossible and snow or very wet road is scary. Just depends on what you need them for.
