I ordered my wheel and tire setup a few weeks back and got them mounted on the car. I got 315 35 17s on the back. I am looking to take it to the track this coming week and i am very curious on how these tires will hook. I cant wait to be able to launch a bit. Is anyone running these, and know what pressure to start at or any tips?

Drop em to 20 lbs., get em hot, try different launch rpm's...really that's about it.

what is the lowest pressure i can take them without hurting performance?

A neighbor of mine said to not lower the pressure in those tires.
He has them on his cobra with a lot of power.
Don't know if that will work out.
JUST TRY THEM UNTIL YOU HIT THE SWEET SPOT.
I put my M&H's down to 17lbs and away I go.

I started with 35 in my 555r's. I went to 28 then 25 then 22 and 20 is where they hooked best without getting too squirrley on the top end. If your not trapping over 100-110 lower pressure won't be too scary at high mph.

good deal, online in the mustang and fast fords, they set them at 25 and they seem to hold. I was hoping to get a tired that i didnt have to drop down to nothing to get them to hook.

I have them on my car and run them about 20-22 psi. I did a few burn outs and the marks are dark on the outside but not in the middle. That tells me I am not running enough pressure and the middle of the tire is cupping. I haven't had a chance to change it and see if it makes a difference.

Huh that is interesting liljay. Do you know how much your car weighs? I know my car transfers weight pretty well. Tell you the truth though my 3 runs of the night were 2.2, 2.18, 2.112 60's so it wasn't like I was hauling the mail out of the lights. The car has been 10.3 with a 1.79 60' with a th400, shitty converter and transbrake at 138. I'd like to see how well I can get these nitto's and heavy 17/18's to hook before I switch to a race set up but at 20 psi it I got my best 60' time. I'll try a little more pressure and see what happens in the next 2-3 weeks.

I know for sure they hook up like none other on the street. I had them at 30 and that thing will book on now.

I don't know how much my car weighs. It's a 00' Firehawk. I would guess it weighs around 3500-3600. That's just a guess though.
