While you may believe that there maybe a potential for not being able to control the bike , I dont think there are any facts support that.
You're right Roy, and that's one of the reason we have not banned it from being ran yet.
You originally asked me about running this tire last year sometime. I told you there was no specific rule in the book keeping you from it (barring the president, race director, chief tech or chief starter saying no). So I said lets see how you and the rest of the organization feel about it if you're set on running it, just make sure to have a standard motorcycle tire mounted on hand in case we deem it unfit for use for whatever reason.
I commend you for bringing it to light here, although I think your "data" thus far is more harmful then helpful to your cause, and we will continue to discuss and and try to make a final decision on it.
Also remember your reasoning of running it was that you were spinning your tire in 6th gear and needed better traction, I will say again that your bike didn't have enough power to spin a decent motorcycle tire. And I also said that there are many MC tires that will stick much better then that car tire at Maxton due to the course surface and layout, as well as me believing you can go much faster without it for the fact of additional weight early in the run and additional drag at the important end.
At the speeds you've obtained there's no major concern for issues so far as long as your runs are fairly uneventful. Best case scenario is you go continue to go averagely fast for the type of bike you're riding, but worse case scenario is what we're worried about.
Discussion will continue to take place both publicly here and privately with the organization and I will keep you in the loop if something changes of course... thanks again for bringing this issue back to lighta nd do keep that back up tire handy for any reason you may want to decide to use it.
