At what point or DR's done
 

I have a pair of BFG DR that have very little visible tread left, at what point are they done?

They are past done. Depending on the car, some go as little as 6 passes, and they are taken off. Generally, on a street car, the wear bars are about it.

when the cords show.

NJSPDER and I think alike. They will still hook when they begin to show a few cords. Keep an eye on them and be safe! When I know that they are close I check them after every pass.

hugger, have you noticed that once they get the tread all off you can go up 1 psi and still hook the same? seems to be the way they go, a few of my friends have tried it with pretty consistant results

I always found them to hook a bit better when the tread is gone

I never messed with the PSI. I ALWAYS ran mine between 17-19 PSI. I know that I cut a low 1.6 once and came back to the pits and was showing cords. That is when I retired them. I just know that I have run about 3 sets of BFG's to that point. Just use your common sense and don't do anything dangerous. I usually wait until I see the first signs of cords then trash them.

Thats what I thought but I just wonderd if people really ran them down that far.

I will began checking them after each run. They do hook up alot better now that they have hardly any tread.

Anybody know how long approx it takes from this point until they show threads.

I ran mine untlil I saw cords.

I have brand new BFG drag radials. But there on my street rims.

they hook better bold

Till you see cords, then enter a burnout contest and finish them off :jest:

On our stuff, the bfg's worked better the balder they got. M/T's are quite different though.

6 passes, looks ill buy in bulk. i do that in a weekend. how do MT radials or 555Rs do? there is a 80 trip to track soo

M/T drag radials hands down!!!! I couldn't believe the difference when I went to their DR. 275/60/15 cutting 1.40 60's with 20 psi and room to play.

Yeah i am totally hooked on m/t's now. Hands down the best drag radial i have ever tried.

6 passes thats it????? I've got the wrong hobby...

once my M/Ts got bald they got slick so i chunked them.

I'm talking EZ street cars, not your every day drivers and mild street cars.

they hook like a bitch showing cords
