i would say 17x8 to mount some 245/40/17 kumho mx's or bfg kd's since no one makes a competitive 245/45/16 for us people in STX

I'd say make Grids in 16x7.5 but it doesn't matter to me much since I already bought 16x8. If you come out with some $500 16x7.5s though I'll have to hunt you down.

17x8, perfect for STX and the 245 series rubber, or larger if you run ESP or SM.

Also, they have to be the same weight or less than the stock rims.

Same here Storm! 15x8, 16x8 or 16x7.5
The slipstream or subzero would look great in that but be able to fit over the STI 4 pots. That is the key. I see that you said that the slipstream in a 16x7 doesn't fit over the STI 4 pots.

Anything 8" wide is great. Go ET45 if possible. I'd love to have 15x8s or 16x8s, but the good STX rubber in 245 width is only available in 17".

I guess all that thinking aloud means....17x8.

Now if BFG or Falken would only make 245s in 15" or 16"...

Have you looked at tires that are not marketed to the US? It seems that they could be imported like anything else, and some are DOT marked.

That's a good thought, but I'm not sure it would work. First of all, the tires would have to be DOT approved and have a treadwear rating of 140 or higher. Secondly, I believe all tires have to be readily available in the US for a certain amount of time before Nationals to be legal. At least, that's how they do the R compounds. It's worth looking into for the street tire rules however.

Default just a thought...that's all

Ellisnc had a Bridgestone tire in another thread that was DOT stamped, yet was not sold in the US (AFAIK).

So if it has a treadwear rating of 140 or higher, it still has to be readily available? Define readily available.

I'm still looking, but it looks like anything wider than 225 in a 16 in size is rare worldwide. 17's are just too easy not to use.

Here are the rules in all their glory, straight from the rulebook. 13.3F is the only one which Street Touring classes are exempt from (4 diameters, min 6 sizes...):

13.3 Tires
Any tire which is O.E.M. on a car eligible for Stock Category may be used. Non-O.E.M. tires must meet the following requirements to be eligible for use in Stock category:
The tire must not appear on the following list, which may be altered at any time by the SEB upon notification of membership.
No tire models are currently listed.

No tire models will be approved for competition during the rest of the year after April 30 of each calendar year. Each eligible tire model must meet all requirements of section 13.3 by April 30, and must continue to meet them thereafter. A tire model will normally be determined by the designation in the Tire Guide. However, any of the following changes or similar changes (as determined by the SEB) will also be considered to represent a new model for eligibility purposes, even if the designation does not change: Change of tread pattern at either full or partial tread depth; characterization by the manufacturer or distributor of a tire as "new" after April 30.
Discontinued model tires already produced will continue to be eligible for Solo II competition in Stock and Street Prepared categories. This follows years of precedence on eligibility for discontinued tire models.
If a manufacturer reintroduces a tire model which was previously discontinued, that tire will be considered a new model. Therefore, it will have to meet the rules specified in SIIR Section 13.3 including the April 30 introduction date.|

The model of tire must be listed in a current or previous two years of the Tire Guide and Tread Design Guide, or otherwise be approved by the SEB. The tire model must have Department of Transportation approval.
Within each tire model, the sizes which are available must be equally available to all competitors. Tire model variations differing from standard specification, delivered only on a limited basis, or only to selected competitors, may not be used.
No racing tire or recap (on any casing) may be used.
Each tire model must be sold in at least four diameters, with a total of at least six sizes.
Tire must fit the allowable wheels and fender wells without modification.
Each tire must have non-zero measurable tread depth (i.e., points where it is possible to obtain positive measurement values) as described in Section 3.3.D. Tires may not have cord visible at any time during competition.

Default In Summary

Availability is not the issue, but one would need to have a tire approved prior to 4/30
