Tire fitment on stock rims
OK, obviously I'm talking B-Stock SCCA rulez here so the 18 x 8 rims have to stay.
Though they will probably be replaced by SSR's
I've read in the forums that someone shoe horned a 275 30 18 on the factory rims.
I didn't catch if it was in the front... So question is:
Who here has replaced tires on the stock rim with larger sizes?
What is the largest tire that can be placed on the front wheels without rubbing at auto X cornering

I did 245/40's on the stock 18's.
It seems like the stock 225' bridgy 040's are usually narrower than most tires that are the same size.
The 245's look like they were meant for the rim.
Someone else did....... I think 255 or 265's with a slick here on the board, and did look a bit big for the rim, but really not that bad overall.
If you are going to replace the rim AND compete, get some 17x8's. You will find that most slicks max out at 17's, and there's not much avail for the 18's.

There are pictures of the 275 Hoosiers on the stock rims (on and off the car), as well as a side by side comparison to the 245's, at the link in the signature.
Also, remember that the Hoosier's have a MUCH stiffer sidewall than anything you will run on the street, so it may be possible to go bigger with a street tire (depends on the class you want to run).
THE MOST IMPORTANT THING! When they were fitted to the car, it was specifically to test the "interference" question. There is NO interference at full lock in either direction (while driving), and at full static lock, there is enough room for a finger between the tire and the lower control arm (the closest point). NO PROBLEM!
I'll let you know how they work out at our next event (Dec. 7th).

Please do!!!
and thanks for the reply.
As to the comment on using 17" rims... Yes there are many good tires for that size (Azenis). Problem is that B-Stock rules do not allow it unless it was an option on this car. Since it was an option on the Automatic, some places will let you get by with them but I doubt National events would.

The DO look nice, don't they? BUT, I bought two sets of stock wheels, one set with new tires and pressure sensors still in them for less than he paid for just the wheels........
I didn't like them that much.

As he uses them for autocross only, he just has a regular valve stem fitted. Both of my autocross sets only have regular valve stems as well.

Now, the NEW Kumho will be out in the spring (Hoosier copy), AND the new Hoosier (A3S04 and R3S04) will be out in the spring (it's available now in smaller sizes - 18" is being quoted as spring). It may ALL change by then....

He said he could have gotten the 285/30/18 on there easily.

Didn't know Karter had picked up an '8 too. Cool!

Karter is the only competitor to have beaten the "target" time at the Mazda "Rev-it-Up" events, and a VERY good autocrosser, so he wanted to give it a shot. Seemed like a good idea at the time.....
I would love to see Karter run one all of the time, it would keep us on our toes, but he will be back in the Mini in January.

There but for a couple of centimeters went I. I beat the target time earlier in the day at the Houston Rev-it-Up, but a late cone call blew it away.
