Start with 24psi and you should pickup about .05-.08 in ET

I run this tire on my Dart SS/JA
I race it at 3490# on a 3470 min
.060 over 383
8" ATI converter
Foot brake with a two step
5.38 gear
1.35 60FT 10.43 @ 126
I use the C06 compound which is softer than C07 and doesn't last as long but will hook a little better. I would start at 18psi and go up a pound each pass until it spins then back off two pounds to be safe! You should pick up a tenth with these tires.

Is the co6 compound the lightweight tire?

Also, if I run these tires on rims that had wheel screws will this be a problem?

Thank you all for your time to respond to this!

Yes these are the lightweight 18214 radials! It won't be a problem to run them on drilled wheels

I run them on my car. Usually around 18.5 - 19 psi. My car is just under 3300 lbs. with Cal-Tracs amd mono-leafs. I've been a 1.29 60' and 9.27 foot braking. They work well. Do a light burnout and flip them every 10 runs or so. I usually kill the sidewalls before they wear out. They are also very stable down track, no sway at all and they don't grow which is nice if your wheel opening are tight.

What advantage do they have over the biased ply slicks of the same dimension?

Less rolling resistance is the big advantage among the others I listed earlier. They are faster.

We used those radials for a season, found them to be less consistent if traction was an issue, we didn't go any faster in the best conditions either .
Some of the teams over here carry both types of tyres on spare wheels and swap if they need too.
