10.5 Tire
 

When will NHRA mandate a 10.5 rear tire for stock classes?
Don't we all think these new classes are getting a little fast for 9 inch?
Lower classes should have option of using bigger tire?

After a few of the new ones crash.

They should have been put up in S/S anyway.

Not needed.

Sounds like someone wants to run their IHRA car in NHRA without changing tires.

Re: 10.5 Tire
 

Hoo-boy! Here we go again! Let's change the rules so that the person going 150+ on a 9" tire and shouldn't be doesn't roll his investment up in a ball! If you can't drive the car then build a slower car! Not everybody has the abilities to run Prostock or TF ya know!

Re: 10.5 Tire
 

X2, personally I like the fact that a slower car may have an advantage on a marginal track...if people aren't comfortable running the new cars on 9 in tires then they should run SS.

Re: 10.5 Tire
 

The guy who owns the new "super car" has a choice about the 9" tire and 145 MPH +. The guy in the other lane has the choice made for him.

When a car running 150MPH on a 9" tire starts to get out of shape, it won't matter who is behind the wheel.

Re: 10.5 Tire
 

Your asking for the end of stock eliminator and trust me it would be no sweat of NHRA to eliminate us and move us all into super stock.

Re: 10.5 Tire
 

Won't fit our car without the old school modifications to fender lips and jacking up the back end - which would not improve traction

:-) peace

Re: 10.5 Tire
 

Wont fit in my car period!

Re: 10.5 Tire
 

lets change tire rule,hell why not just change all the rules to suit yourself,maybe we dont need any rules at all! All this pissing and moaning about the current ,or should I say traditional eliminator rules is gonna make me puke! Its your choice what you drive, if you need bigger tires or unobtainable parts why is that everyone else's problem? What about the poor soul who cant fit the 10.5 tire? They get minitubs now? Run in SS if you feel the need to have big tires and dont feel safe! Lots of guys going real fast on small tires in the other associations , why cant they do it in NHRA stock? Plenty of places to race these BS combos elsewhere, where they would be welcomed im sure. Why try to shove all this bogus crap down everyone else's throat ? The racers who have raced stock forever and supported the sport long before these new "saviors for class racing" came along!

Re: 10.5 Tire
 

10 oh and lots of faster cars will hook fine on 9". If you cant make that work, go to SS or bracket racing until you do.

Re: 10.5 Tire
 

All I did was ask a question to see the reaction.
Pretty much what I thought.

Re: 10.5 Tire
 

Then do the tire manufacturers have to step up?

Re: 10.5 Tire
 

i would assume you have never been in a car with small tires running faster then in the tens? i have had several "small tire street cars" that ran well into the nine second zone with 295 65 15 tires no problems, i have a friend that has a 390 ci nitrous small block mustang runs a 275 radial street tire and goes low 8's straight as an arrow,i have had more problems staying hooked with 15X33 tires on my modified car down the stretch than anything else. so i do not think there is a problem with stock eliminator and the tire size we are running right now, it actually is the one thing that evens out the class when high hp comes into play,and as for guys being worried about cars getting loose and crashing, when was the last time anyone saw a stocker do that? and if one does ? well thats just racing !!!!

Re: 10.5 Tire
 

I spoke to the Ford representative at the PRI show in Orlando this past December, He told me that he was going to petition NHRA for DOT Drag Radials for Stock Eliminator. He said that the tire manufactures have put more effort into the radials and that they would be safer at high speed.

Re: 10.5 Tire
 

No kidding? Why don't they just actually read the damn rule book??????
Very first sentance!!!

TIRES
Street-type or drag slick tires, maximum 9-inch tread width. Tires may not be altered from tire manufacturer’s original design or pattern. Size of tire (new) must not exceed 9-inch wide x 30-inch diameter (94-inch circumference). Tires may not exceed 10 inches wide regardless of wear. Front tires must have a full street pattern and must measure a minimum of 4 1/2 inches on ground. Tire tread may not extend outside fender; maximum clearance between side wall and body is 3 inches. Slicks permitted on FWD cars. All-wheel- drive vehicles must have treaded front tires. Recapped/retreaded tires prohibited. See General Regulations 5:1.

They probably should have read it before these cars were even allowed, but that's an another subject.....

Re: 10.5 Tire
 

The gentleman that I was talking with is the person who brought the Cobra program to market, I have spoken to him at Indy when they had the pizza parties 3 years back. I'm sorry that I don't remember his name, but while at the PRI show, we were discussing on how fast the new 5.0 factory race car was (the new car that they where showing) and that the cars are almost going too fast for 9" tires. That's when he said that he was going to suggested DOT drag radials for stock to NHRA. I personally think the way you are thinking, leave stock alone. Go play in another palyground with new rules.

Some super stock cars run 9" tires to go faster!

Re: 10.5 Tire
 

Sorry to break the news but you guys are only fifty-two years late to be complaining about eight-second elapsed times or big speeds on a nine inch-wide tire. You should've directed your concerns to a Mr. Socrates Christopher Karamesines in April of 1960 when he ran 8.80s at over 204 mph on a pair of 8.20 X 15s.

I won't even bother telling you the record for a nine-inch tire since it's over seventy-five miles per hour faster than even a AAA/S entry will run.

Re: 10.5 Tire
 

Im not a class racer(yet), but, to me, the thing that has always drawn me to Stock, is the factory parts and 9" slicks... Introduce 10.5's or DOT tires, and everything STock stands for, is lost...IMO Pretty sure IHRA allows 10.5 slicks, but, I dont know why.... I saw plenty of 140mph cars at INdy in 2011 that
didnt seem to have any problems... Far as im concerned, any new car that is factory turbo'd or supercharged, should be classified as SS or FX, with their own rules...and should run in SS... or a class called Factory Power Adder Stock... FPAS...

C'mon now Bret. Quit clouding the issue with facts. :)

Re: 10.5 Tire
 

Amen !!!

Re: 10.5 Tire
 

Last year I spoke to the Goodyear drag racing engineer that happened to be at Pomona. I brought up the subject as regards to the high speed in Stock Eliminator with their 9" on the CJ's and DP's.

His response was the tire is designed and tested for speeds over 160 mph and cars up to 4000 lbs. He also stated, just like Mark/A56 shared, that it is up to the racer to have the appropriate suspension setting to run the high speeds.

Re: 10.5 Tire
 

I thought dot drag radials were legal as long as they weren't larger than 9" or 94 circ?

They are in D2, my friend has a Corvette that he drives to the NHRA national and division races, he uses drag radials.
