I just purchased a set of BF Goodrich Comp T/A Drag Radials and I'm not sure what exactly to expect. Does anyone have any suggestions for air pressure? Anything else I should know other than "don't try to launch in a rainstorm"?

 

Goddamned typo

Care and feeding damnit.

 

I don't have any drag radials, but I'm going to say something like 18-20psi..

 

I run 12-16lbs of air in mine depending on track conditions. I usually just heat them up till i see a little wift of smoke then let out the brake and let it roll forward till it grabs.

 

IIRC you have to give them a good inital burn, but after that you dont want to heat them up too much because then tend to ball up and get greasy...

Its been 5 years since I had my last set, and my truck burned before i ever got to use them.

 

On the same note, what about nitto 555r's? I contacted nitto a long time ago and they never bothered to reply.

 

i seemed to have best luck with 14lbs on my 255/50/16s on a 70* night at great lakes dragway in wisconsin. bfg recommends just enough of a burnout to clean them off, "the traction is in the compound"

 

Figures... The sidewall says to air em up to the specs the tire card recommends... At 30psi they spin just as bad as the Comp T/A VR4's and my times were just as bad if not worse as a result.

So I need to drop the pressure about 50% and spin em till they just start to smoke, then they should stick?

Are they going to stick like glue or just stick better than street tires?

 

Somewhere in the middle.... There are cars running 9s on em though

 

These tires can stick like glue. There is no comparison to street tires. You just have to know how to use them. I hit low 1.6's on them with ZERO wheelspin. They would have held high 1.5's on my setup and that was with a full weight car.

Don't pay attention to 'just cleaning them off'. You want to make sure you get smoke from BOTH tires and then burn them for almost 5 seconds. Treat them like a slick and they will stick like glue.

Hehehe I feel like I'm signing the death warrant for my well used posi and 700R4, but to hell with it, if the car's going to go faster its time to eliminate the weak links.

So heat em up and let em eat. I was just a little bit hesitant to do a monster burn out on these things... I'd like em to last a while, but if they gotta be hot to work, so be it.

Thanks guys, I'll have to post some new times after a trip to track.

 

They will last a short while with regular driving, depends on size. Most of the guys down here that are running 275/40 or 315/35 on 17s can squeeze about 8-10K out of em if they try. Those are hard use miles too, BTW. Lots of burnouts and races. Or course, you can wear them out in a week if you are in a race, so it mostly depends on your driving when you are not racing...

I have had minor traction issues with mine on just damp streets @32 psi so watch out...

 

Do as Traxion said. Be sure to lower the pressure when you get to the track. And put the pressure back in on the way home or before the next trip to the track.

They need radial pressure to last and act like a radial, but need less psi to be the slick.

When I get mine, it's going to be a bolt on at home for the track, take them off when I get home. Street tires only for the street. These things are too expensive to drive on everyday.
