Drag Radials
 

We are going to put a radial slick on our car for the first time. Any suggestions on tire pressure to start with? we run about 14.5 with the regular good year 28x9 slick on a 8 in wheel.. will be going to the 30x9 goodyear radial still on an 8 in wheel.

this is an 88' mustang around 3100ish pounds 60's in the low 1.60 range @ 6000 DA as of now but we changed the rear gear from 4.88 to 5.13 as well. so I don't know what the 60's will be with the 28x9 until next weekend then we'll run the slick after we have a baseline with the old tire..

thanks guys

typically 5 psi higher than your typical bias slick pressure is a good starting point and you'll go higher from there.

That said, if this car didn't work before, it will be worse with radials.

Car works great 60's within .010 all day just trying some new stuff.

What kind of burnout should I do with the radials? Bigger smaller or the same as with the bais slick?

Re: Drag Radials
 

I would put them on 10" wheels. I used to run 9"X30" Hoosiers when I was bracket racing mine. Mine hooked better with more air on the 10" than on 8" wheels. Fastest passes it made on those were with 23 to 25 psi. They were well over a tenth quicker than same size bias tires, A-B-A (back-to-back-to back) same night.

bias or radial, many do too long a burnout. Tires need to be cleaned, not heated or worse boiled.

My burnouts are no more than 4 seconds.

Been running radials for the past 14 seasons and ain't ever seen a tenth no mind quicker with my BBC cars.

18-22 lbs should work, you should see .08-.12 quicker et in a low hp car. Radials don't grow, you should see around the same finish line rpm or slightly less than the 28" bias tire. The car will feel different with the radials, more like a street tire. They're great until they spin, then your done for the day. If your bracket racing on a marginal track stick with the bias tires.

Ed,

we debated between the 8 and the 10 inch wheel the 8 just seems like it is going to be easier to make fit and we are only going in the mid to low 12's so we wanted a smaller footprint on the ground.. if we made the power you did no question we would have gone with the 10 inch tire. This is all new to us... only ever ran a bias slick so 20 23 25 all seems like wayyy to much air.. haha heck the 14.5 we have in the bias tire is way more than we usually run.

1320.. were only looking for .05.. any more than that is icing on the cake.. but we've heard from several.... lets estimate on the low side and say 25 people with multiple combos and all have told us we could see up to a full .15 faster... maybe youre doing something wrong.. just saying

Absolutely agree............I just chuckle when you see a door car do a "John Force" type burn out. A waste of time and money.

Re: Drag Radials
 

radials were worth .7 on my mustang. 22-25lbs worked great with hardly any burnout. see smoke, roll out!

Re: Drag Radials
 

What width wheel did you run bob? And what size tire were you going from before the radial? 28 or 30?
