Radial tires
 
Are the new Goodyear 9 inch radials the fastest tire and how about reliability and longevity. Thanks for input

I get great life out of the Goodyear’s and the car hooks if we have any kind of track for the pink car 3200# car with close to 600 ft/lbs of torque. On Dumbo I have not gotten the repeatability down with the longer wheel base and heavier car with 100 more Hp.
A 100 plus runs is not a problem. The service and support at the track is very good.

I had 96 runs on my Goodyear tires on my A/SA 2019 Challenger. Like Larry said, the longer wheel base can be a challenge at times, but I was very happy with them.

Mark,
I went to the Goodyear's on Terri's Nova and will NOT go back to the Hoosier's.
They are as fast and last much much longer.

I put them on Terri's new car as well when I moved her to the automatic.
I won't run anything else.

Wow the pink car is 3200 lbs!!!!!!!! So which part number are you using ?

Glenn if you do a search Larry gave all that info in the past. It sure is worth a try.

Larry Hill 10-29-2022 08:49 PM

Re: Radial tires
 
Glenn it’s the big tire 94” roll out. With the taller tire I think I get more of a contract patch due to elongation on tire deflection. For me and the car to be in the 3200# range I have to be in the 250# range.

We run Goodyear Radials on all our stock and Superstock
cars!

Goodyear recommends a 9" tire width maximum. Are you using 9" ? What Goodyear compound have you using ⁿ0 and like for your weight car. ?

Steve Teeter Stk/SS 620.

Re: Radial tires
 
9" rim width I meant.

GTX JOHN 10-31-2022 11:05 PM

Re: Radial tires
 
We prefer 10 inch rim.

Has anyone tried radials on a stick car ? Will they work ?

A few of us have. They can definitely work if you take the time to set the car up for the tire.

Larry Hill 11-08-2022 07:27 AM

Re: Radial tires
 
We have 9” and 10” wheels and can’t tell the difference with the tire. We run the harder compound. Of the stick racer we know including our truck the radials are quicker. The challenge is the first 60’

Re: Radial tires
 
Larry Hill you have a PM.

Larry Hill 11-08-2022 03:09 PM

Re: Radial tires
 
The current compound for the Goodyear tire is the D1B.

Bill Bogues 11-08-2022 08:22 PM

Re: Radial tires
 
We went to goodyear radials after watching Jimmy hildago jr run his stocker. I noticed he didn't seem to do much of a burnout but always hooked up.Talked to Goodyear people and they told me not to do a burnout, just spin a little to make sure tires are cleaned off. Started out with .190 worth of rubber, At 105 passes they have .115 rubber. Never spun.Finally took them off at latter part of year and put a new set that I had bought a year ago.Old tires still had over .100 left. Cost more but a lot cheaper overall, especially to some one who runs our tires until cord shows.

Re: Radial tires
 
I've been running radials forever, and I haven't used the line lock for a burnout in over 20 years. As light as possible. Low to high and lift.

Larry Hill 11-09-2022 04:13 PM

Re: Radial tires
 
We do the abrasion process in second gear to keep wheel speed down and to keep tire from “Crowning”

Doug Hoven 11-10-2022 09:39 AM

Re: Radial tires
 
Here in the Hoven racing camp there's a set of 92.5" Goodyear's floating around with what we figured to be over 200 runs on them. They went about 150 on Todd's firebird, then another 50 or so on another car with no issues. They still have some tread left on them. Ultimately they just sort of stopped making smoke in the burnout so they got taken off the car. I can't speak for the Hoosiers, but we tested the Goodyear's against a set of M/T stocker radials back to back, and the Goodyear came up about .03 - .04 faster.

Re: Radial tires
 
It's been quite a few years since I tried Goodyear radials.
From what I remember, they may have been a little faster,but I had more inconsistency.
Everyone has their own opinions,but in my opinion, the Hoosiers are tough to beat.

Larry Hill 11-10-2022 11:03 AM

Re: Radial tires
 
When we were at a tire test we did two back to back tire tests, within a time window and the Goodyear’s on my Cuda were quicker and faster than the Hoosier Radial.
For me besides the great longevity is the ease of the rubber removal from the rear fenders.

You need Daryl to hook you up with some of those mud flaps.

Re: Radial tires
 
I tried a significantly shorter burnout this morning at World Finals,
But the car exploded the tires immediately. Second pass went back
to regular burn out and no problem. 18 PSI's both passes.

Can you elaborate?

Larry Hill 11-11-2022 07:58 AM

Re: Radial tires
 
No mud flaps for me it’s to much aero drag. I loose it or gain it .001 of second at a time.

Radials need to be dead hooked with even then increasing pressure right off the hit to work consistently. Basically just like an automatic car leaves. If your car pounds the bias tires hard to make it leave it may not be able to hook radials. Good shocks, sorted suspension and data logging go a long ways.

Re: Radial tires
 
Troy you must be the only guy running them
It’s has to be faster.
It’s been said a radial tire could be 1 tenths faster. Than a bias ply
Good job

Good job

Their is quite a few stick cars running them. Markus Svennson was testing them back in 2019.

Fast shocks

What rpm difference is there at the top end between bias and radial with the same rollout for each?

150 to 200
