Advantage radials to Bias Plys
 

How large is the advantage of a radial to a Bias Ply? I know of all the advantages of a Radial tire but in reality how big is the gap especially on a slow U/SA? I know its rare to see an Auto car with slicks nowadays..... How large is the gap in ET/Speed? Can you still win a National or Division on Bias Plys are they consistent enough to compete at a high level?

Worth at least a tenth to twelve hundreds on my N/SA Mustang. I guess a lot would depend on how high air pressure you can get away with in your bias tires.

I found about a tenth with a lot of that in the 60'. Also helped reaction times a bit, less wrap up.

I went 2.43 under with the bias ply slicks and was afraid to run the radial.

Had both on U/SA olds wagon. No difference other then the air pressure

Back to back on my car within 20 minutes at NED, 5 hundredths.

Not to thread hi jack but any stick guys using radials over slicks?

Re: Advantage radials to Bias Plys
 

We had them on the truck testing and radials were quicker and faster, but only hooked 20% of the time. Maybe with some work it could be a player

Re: Advantage radials to Bias Plys
 

We put them on a friends P/Stick car years ago and they were awesome!

Tried them on our Nova off and on. Never figured out how to consistently hook. Encouraging but in hot track conditions we didn’t have it figured out.

Someday maybe we will. Interesting idea.

There is an A/Stick car running them all of the time. Not sure if you can say it is quicker ,but credit to him for getting the car down the track most of the time.

The more time your car spends on the track the more they are worth.

Don't waste your time and money on bias plys
You're dealing with a new combo that may not be the best for U/SA.
Don't leave any ET on the table.
There are plenty of used radials out there for sale from the higher class cars , that will work very well for you.

Same here on the stick application, went a little faster but blew the tires off about 1 run in 4. Can't win any races that way.

This is what I did. A used set if bias and used set of radials. Bias finally cracked to much. Radials have plenty of life in them but it looks like Az sun exploded one of the tires on car last week. Guess I should have covered them up.

Re: Advantage radials to Bias Plys
 

That was the V/S combo in the truck. If you have the power to use them Goodyear 1909 is a good stick tire.

Re: Advantage radials to Bias Plys
 

Well its not about the cost of the tires its about the cost of wheels Mark... I have 14 by 7 wheels currently and You can find a M/T Slick or Hoosier Slick that would fit but with a different set of wheels I would run the Goodyear D4892... Ive always pretty much been a Goodyear guy ive always ran Goodyears on my No Box bracket car but I mean wheels are very expensive but I did find some Wheel Vintiques wheels that might work.

15" x 8" on a 4, 1/2 bp shouldn't be too hard to find on C/L or swap meet.

It s been quite a few years ago since I went from Bias to radial. When I made the switch I made two run with the radials and took them off. They were ill handling. I put bias back on and ran it that way for several more races. I was forced to put the radials back on the car one day due to getting a flat. I put the same air pressure in the radial as in the bias and the next pass was 0.13 faster than with the bias tires and handled perfectly. Both times I tested this the result was the same . Since then I run the radials all of the time and run them about 13 psi.
This is a super stock car and I run the Hoosier 13.5 x 31.5 radial
