UMSS at Ogilvie this Saturday night.

AJ's Dad, the DQ on the #79 was because there is a wheel and tire width rule for the left rear of no more than 15" wide. The right rear has a maximum width of 18" so a left rear is not illegal and the tire compound numbers are G100, G200, G300 for both left and right so a left rear appears to be a legal tire on the right side of the car.

The width rules came into affect several years ago because there started to be 16" lefts and 20" rights that promoters said were causing some of the problems with tracks drying out.

Ryan you are incorrect, look at IRA site, the 83 got DQ'd for the tire. There is a rule you have to run a lr on lr & a rr on the rr, ask Howie.

Biggy Johnson, I see that the 83D was DQ'd. If I was a competitor reading the rule book I would say the following informatioin pulled from the online rule book does not clearly specify that an actual Right Rear tire has to be run on the right side of the rear axle:

This rule could easily be read as needing to have any one of the 3 compounds of Goodyears on the left and right rear of the car. Since the Right Rear and Left Rear Goodyears have the same compounds. I know if I was reading the rule book at the track, this wording is very open to interpretation. There is definitely some room for improvement on details to this rule.

I was standing by the scales when the 79 was DQ'd & over heard Howie telling many people that the Goodyear contract has specific size's of tires that are allowed on each rear corner of the car. I wouldn't know for a fact other than the Goodyear rep said it to many people at that time. I specifically asked if we could do that exact thing after the B & was told HELL NO because of the contract! If they had a question he should have been asked as I did & now everybody knows for future. The rules are the rules & if anybody has questions there are many officials who can be asked before shooting yourself in the foot, if your going to look for the gray area your eventually going get burned.

Well Ryan. Why did the 2 cars in question get DQ'd then? I suppose if there is a gray area in the rule book it needs to get cleared up. It was worth a try I guess but it did not work out to well for either team.

So what would be the advantage of running a left rear tire on the right side of the car?

he was trying to get less stagger because the track was so dry & slick, the 79 put 2 r.r. tires on in the b main & walked away from the field then was Dq'd for it so the 83 assumed that 2 l.r. tires would be acceptable. The IRA has a rule on what size tires are allowed to be used on both rear corners & you cannot get below 10-11 inches of stagger I believe.

you can get down near 6 or so

AJ's Dad: talking to the #79 after the B, at the scales they told him he was illegal because his wheel was wider than the max 15" for a wheel mounted on the left side of the rear axle. They even told him if he mounted the tire he had on a 15" wide rim it would have been legal.

As for the #83D, being DQ'd I have not heard what they were told.

The track conditions are what lead these teams to try something different to improve their traction across the rear of the car.

Biggy Johnson: as you see by my post the IRA rule book itself doesn't list a tire size rule. I can understand what you stated about the Goodyear contract, but that is not the way their rule book reads. I also understand your point about asking before shooting yourself in the foot.

The track sucked. I understand a guy has to try something different to get the car to work on that bad of a track. But there are rules to follow also. We had to try and set up our car to work also within the rules. I do not think that tire would have been legal on a 15 rim. Have to ask Howie and the IRA board on that. So apparantly the rule book needs some clarification. Whatever it takes the 2 teams gambled and lost. Later.
