i presently have an 07 with 275/40-17 nitto NTO5R DR and i cant keep traction off the line. I have 456 rwhp and 439 torque on a mustang dyno and 3.73. i want to switch to mickey thompson ET streets. either 275/60 or 275/50 in 15". i want to buy a new stang maybe next year and what size in height would work best for both cars? i think the larger diameter tire would work best.

 

I have MT ET streets mounted on stock 17` wheels. They grip like a vise off the line. I dont drive around town with them though. You can but I wouldnt. Bias ply with all that sidewall is the ticket for FI cars like ours.

 

is the bias ply that much better?

 

Huge difference on the track. They last longer than drag radials on the track too, but on the street, they will not last. Do some some searching lots of good info out there. I got the rims local off a craigslist ad for $100 and tires from brenspeed. The best mod for the track period. With my auto trans I run 30 psi. Down side is if you run a real low psi, you can get that floaty feeling at the top of the track. My best 60 ft has been with the higher psi. Manual cars are different.

 

I have drag radials, got them in 2007 from a member from here. Got about 3000miles on them and about 25 passes at the track. I wouldnt run anything but a radial tire on the street. And my car dead hooks with a very minimal burn out. Or I can burn them down like John Force and still dead hook. Best of both worlds IMO!!!

 

The best DR I've tried was a 275/60/15 MT ET Street. Since I've switched to bias plys, I've had better luck with 27x11.5x15 Hoosier QTPs. The difference between DRs and bias plys at the track is no comparison. Bias plys all the way.

 

Which of the DR's are streetable aswell? Like the best of both worlds hooking on the street and at the track?

 

you cant keep traction on street or track?
