Yeah, you read right, and I'm ducking behind my monitor as I type this...
But yes, I'm contemplating requiring spec tires for 2013...
It has been proven many times over that many times a car is dominant because it has a "good set" of tires on it. So with that in mind, I'm thinking of requiring all entries to use urethane in an effort to "tighten up" the competition. I'm leaning with these because they are fairly easy for guys to get, easy to true up, and they grip fairly good on most tracks.
By requiring urethane, I'm also hoping to be able to get new tracks into the series that normally ban silicone tires.
So the question is, which brand of urethane tire? My thinking is one brand will most likely always have an advantage over another brand (whether it be Paul Gage, Ortmanns, Yellow Dog or any other brand). My thinking is to have all cars on equal footing as far as tires go. I even contemplating each class run a specific brand.
But before I get too far in this line of thinking, does this appeal to any of you? Or will this make you not want to enter?
I like the idea of a spec. tire. Though, I wouldn't chose eurathane, too much variation from my experience. I think the new Supertire 1408R and 2112R would make the perfect slipon spec. tires.
Unfortunately, except for A/B production, few of the cars can fit 17x10's or wider.
Are there any plans to produce rounded shoulder 1403's? The new rounded shoulder supertires come from new molds and are nearly true out of the package. IMHO, silicones are the most consistant from lot to lot and are tamper proof unlike rubber.
Am OK with spec tire of whatever make, as long as there is one available to fit a scale 13" rim (~12mm visible rim) for U class cars. No problem cutting a wider tire down to spec width, it's the hole size and rib (if any) fit I,m worried about. Oh, an' ya gotta tell us what wheels the spec tire fits on.
After a perusal of the web, I see a couple of factors that may be negative indicators for NSR tires (comments to the contrary welcome):
1. I don't see any NSR tires for scale 13" wheels other than the very wide F1 tire, which I doubt could be easily made to fit a 7 or 8 mm wide rim.
2. Ran across several discussions on "treatment" of rubber NSR tires with various compounds to improve their grip, which makes me somewhat uncomfortable with having this as a spec tire. There were numerous claims that it is undetectable (if small amounts of compound are used) and that while the performance eventually drops off to that of untreated tires, it is initially quite significant. If both are true, then any rule forbidding chemical treatment of tires would be unenforceable and there is an incentive to use it. It's a temptation I'd rather not be placed in front of entrants (I coached an Olympic sport professionally for 15 years - ask me why I'm a tad cynical about chemical enhancements in competition ).

NSR make a 15X8 tire. For the smaller wheels let me recommend Slotit P6s.
The only chemical enhancements we use is to clean them with lighter fluid prior to each heat race series. We use sticky tape to clean the tires between each race in the heat.
Spec tires??
NSR rubber 
..yeah?..
