Planning to buy some new slicks for my 70 Torino with leaf springs and caltracs. I'm currently running MT ET streets 10" tread x 28" tall. It has a stick shift and I'm trying to figure out if the 9x30 radial slicks will work well with that or if I the bias ply of a similar size will work better? I'm not sure if the radials work okay with a stick shift or not? The car is traction limited so hooking it up is the number one concern.

Stick shift cars works best with bias ply tires.The radials do not recover from spin as well as bias.

Bias slicks have more flexible sidewalls that absorb shockloads better than the stiffer sidewalls of radials.However, radials are 'deformed' less as they roll, so there is less rolling resistance. If your car can hook just fine on radials, it will usually be faster with them. Good Luck! ------------------

Thanks guys, That's kind of what I was thinking. But with all the changes in tires in the last few years I thought it wouldn't hurt to check into the radials again before I make my purchase.Supposedly those new MT ET street radials do pretty well too, but I've been very hesitant about trying them with a stick shift. They would probably be similar to the radial slicks. Anybody heard anything good or bad about the Hoosier quick time pro tires? They make a nice 10" tread by 29.3" tall with an 11.9" sidewall I have been considering.

I have been running Hoosier Quick Time Pros for 2 years. Running mid 10s with a best 1.46 short time. I'll say they are great for a street/strip car, but I'm considering buying some real slicks for next year. I'm still after quicker short times and I think slicks will do better. I'm spending more time on the track and less time on the street.------------------

I spoke to the local Hoosier tire place there in Clermont today. He said the real drag slicks would probably work a little better than the quicktime pros with my car having a stick shift. He felt like a softer sidewall with a harder compound would work well. I like the DOT aspect of the quicktime pros though. So it's a tough decision.

A heavy car like yours would probably respond very well to a "softer" compound Goodyear 9 x 30 radial drag slick beter than most other stick cars.
We have had quite a bit of success with them on several applications stick and auto with trans brake.------------------

I've noticed the recovery thing... Stockers with radials launching hard then billowing huge white clouds of smoke like a funny car when the tires spin and the car almost stops moving. Bias tires will usually just spin some through first gear while still moving hard and making very faint smoke. The radials seem to make for an aborted run if they don't hook. A few guys i talked to only run them for qualifying. I asked why and they all said the same thing, if they spin at all you've lost at that instant unless the other car redlit.

Yes it is true that radial slicks do not recover.
The key is to having a car that works well enough to hook them.  ------------------
