Im getting conflicting information so I wanted to see if anyone knew the answer.
In any stock class, can you run Hoosiers as long as they are the same size as OEM?
I ask because I thought they were not allowed however, I see 2 drivers stating they are running hoosiers. One in (SS) and the other in (DS).
Just wanted to get some clairification. I thought it went by treadwear and I dont think Hoosiers have a treadwear that is compliant with the stock regulations.

Hoosiers are legal for stock classes... yes. That was one of the things that blew my mind when I came into the sport, but the Hoosier A6 is the tire to have for stock.
Only ST* and Tire class require 140+ treadwear tires. Stock merely requires DOT legal.

That's been a big debate for years, running DOT-legal race rubber in stock. Some like it, some don't.
We offer a "Tire" class if you don't have race tires.

Dang. That is border line unfair don't you think. 220 vs 40 wear. But cool, thanks for the clarification. Now I know what tires to get in the future.

The Hoosiers do NOT have to be the same size as the OEM tire...The wheel they go on does. You can run as big as a tire as you want in Stock class as long as it will fit on the stock wheel...

or a stock equivalent ( re. aftermarket/lighter ) and the offset has to be within 1/4" of stock

Stock classes are Hoosier classes and will always be that way. If you do not want to buy Hoosiers for $1200-$1500 per set, you can compete on your 220 treadwear street tires in Tire Class, it is a very competitive class and quite fair. |

You can run the new RT Stock classes at National events which only allow street tires or as mentioned above just run the local Tire class . They were developed to keep everyone from having to buy hoosiers

Stock allows replacement wheels as long as they meet manufacture sizes for the vehicle. There is a slight tolerance for offset. Tires are DOT R-Comps, aka Hoosier, and size is unrestricted other than what you can get on the wheel and not rub.
There are many options outside of slicks. Depending on the car and how far you want to go. ST classes are a lot of fun and allow a good amount of mods. You could do all other stock class allowed mods and run in Tire PAX class. Tire class takes all cars, except ST classes, that have various levels of prep on street tires and run them against each other. You figure out what class your car would fall into assuming you had slicks and that is your base class and pax factor used.

Depending on your cars OEM sizes - you can purchase Road Race take-offs at a fraction of the new price. My BFG R1's are not as sticky as Hoosier A6's, but they are WORLDS different from my street tires. Would they cut it at national events? Probably not. But its a cost effective way to go at the regional level- if size and availability work for you.

The rules are the rules and I am completely on board with them. I was told two different things so I wanted to get clairifcation on whether or not Hoosiers were in fact legal for any particular stock class. In fact, I kinda welcome it since the R6 ho-ho's were a tire I wanted for both autox events and my track days when I gain more experience. So its good to know I can get these tires and not be forced into a different class because of them. I just didnt think you could technically be in the same stock class with someone running slicks basically vs. someone with a street tire.
I will read the rule book for how Tire class operates and probably enter it next year if I decide against the R6 tires.
I appreciate all the feedback and responses!

there is a diffrence from the A6 and R6 the A6 is faster in a autocross and qualifing laps. the R6 is better for multiple laps under race conditions and last longer.
We have seen A6's Sizies as large as 275/15 on a 15X6 stock size rim on a Integra type R and some Miata's. and tey are faster than the 225/15 that feel better.

I've been wrong many times in the past ... and that could be the case this time .... but something is tickling the more dormant of my brain cells .... but I seem to remember that "slicks" aren't allowed in some of the classes ... and I "think" that Road Race take-offs would qualify as "slicks" as opposed to R-Comps .... |

"slicks" are true race tires and are not allowed in Stock or Street Prep.
Some road race take-offs, like what Eric is talking about, are DOT legal R-comp tires. Showroom stock and Spec Miata (for two) have to run DOT legal tires.

If you're considering road racing castoffs, the most popular....
Spec Miata runs 205/50/15, usually Toyo RA1
MX-5 Cup runs 225/45/17, BFGoodrich R1
If you don't run those sizes.... things are a bit tougher. I've actually considered getting a set of used MX-5 Cup tires and trying them on the MINI sometime, but I don't particularly want to buy a new set of wheels for it.

DOT approved is the key. |
