Has anyone run these with any success? If you have what pressure did you run? How hot did you get them?

I run M/T 29.5/11.5 on mine. Air pressure at 11.75-12.0 lbs. I do a pretty good burn out, but probably more for the driver and the show. Car leaves wheels up every pass and carries the fronts almost to the 60' on a good run. Car is 3200 lbs, modified SS leaf springs only (no cal tracs, adj shocks, no pinion snubber ect.) Stock front 6 cyl torsion bars. Foot brake, Turbo Action "J" converter.

Thanks Brian. I really appreciate the response. With Phoenix's on back order I put the Mickeys on. The first run it spun with 13 3/4 psi 1.53 60'. First round with 12.5 psi it dropped to 1.47 with alittle spin. Then with 12 psi it was 1.45. I didn't want to go lower till I talked to someone. Again, thanks for the response.

Use your tire gauge ONLY and try letting them down 1/2 lb at a time until you get your best 60 ft. times don't forget that all tire gauges DO NOT read exactly the same I have three different low pressure tire gauges, 2 Moroso, one high dollar C gauge, you guessed it, they do not read the same on the same tire on the same day one after the other. I keep one in the car and use ONLY it on my tires I don't loan it out, EVER I learned that lesson the hard way twice, loaned two different ones out and they both came back reading 5 lbs or more with no pressure in them, NO MASS It seems to me the last set of M/T drag tires like your using (I use the 13.5x30x15 ET Streets and the 315x60x15 ET Street Radials and the M/T 10.5x31x15W drag slicks on my car now) my car liked below 10 lbs on my gauges for the best 60 ft. times

I run the 29.5x11.5 on a ten inch rim. Been 1.28 sixtys and hi fives in the 1/8.

Start at 13psi and find what it likes.

M/T tech dept called me back, and said not to look for any consistency until I have 4-5 passes on them. He also stated that with my car being as heavy as it is not to go under 12 lbs. He was figuring that the pressure should be between 13-14.5 psi. I guess time will tell. Testing on the 13th. I'll get'em figured out.
Thanks everyone for the input.

Yeah I threw myself a curve ball mid-season switching tire brands. I should have done it at the beginning, but the Phoenixs still had plenty of rubber left. The sidewalls on the other couldn't handle a 3rd season

They are the slicks. I very rarely change anything in my setup once the first pass is made, but Phoenix forced me into a change.

I really like Phoenix tires too. But theses M/Ts are a great tire. I think once you find the sweet spotyou will be happy.

Hemi-its. I think you need a slick

I have faith that I can get them to work. Hopefully everything gets ironed out next Friday
