My car, 1970 Cuda S/P car that weighs right at 2800 Lbs. with me in it had a set of old Goodyear 16x33x15 on it when I bought it mounted on 15 inch wide rims, those 8 yr old tires like between 7.0 and 9.5 lbs. pressure depending on the track, 1.27 to 1.34 60 ft. times. I put a new et of M/T 14x32x14 stiff walls on the car and they liked from 7.0 to 9.5 lbs. also. My car is nose heavy, 56.4 % (1479Lbs. on the front and 1230.Lbs on the rear tires with me in the car)on the front tires and those tires work okay. I changed them last year to a set of Hoosier 13.5x32x15 D06 slicks per Hoosier recommendations and they liked between 7.5 to 9.0Lbs pressure but they don't always stick well with out a long burn out I'm going to change them to a new set of Hoosier part # 18370 DO6 15x33x15 and hope they wok better than the smaller ones did I have thought about buying a set of Goodyears instead of the M/T or Hoosiers but I'm going to try the Hoosiers one more times and hope they work better than the other ones did On your deal I would try lower pressure, 1/2 lb. at a time, and see if the reaction times and 60 ft. times get better

Funny this came up, been thinking of getting a new set of slicks for the Challenger as I may race it as a back up car from time to time with the the Road Runner being back. That being said it is about the same as Cab's car, 2700# with me in it 1.28 60' but with my motor set back I am very close to 50/50. I have ran Good Year 33x15x15's 2078's since '2003 on it except once when I went with the Hoosier 32.5x14.5x 15 and that tire was all over the place sometimes it would dead hook with the wheels 2 feet in the air the next time front almost on the ground and some spin so tough to dial...... GY's always 60' like a xerox machine but cost $60 more. FWIW I am always at 8# of air and no less than 7.5, at 9# it is way inconsistent with the GY. So subscribed, my .02 That all said I have been thinking of trying one of the M/T in something around 32.5x15x15 ....

When considering slicks these days, I think it would be foolish to not at least consider a radial. M/T makes both a PBR and PDR in a 32x14/15. While I only 60 in 1.56, The PBR has been undeniably a better tire than the ET Drags I had on the car before. I have a buddy that 60’s low 1.4x’s off a transbrake; he also loves his PBR’s.

If your track preps decent, then I'd look into a radial.
I haven't seen a car that didn't go faster w/ a stiff sidewall slick compared to a standard sidewall. Granted, every time I've seen this done it was on a car faster than a 1.4 sixty foot. It was my understanding from years ago that a "W" tire had the same stiff sidewall...in a M/T anyway.
