I had IT cars when this was first considered , about 6 yrs ago. I now run Prod cars only . I really have no dog , (I miss my Dog)
These are my observations ;
I have been racing on 200 TW tires for 8 yrs. The smaller sizes can get greasy when over driven and asking for repeated turns. Like Roebling road on 205/15 tires. The answer is to use large tires and keep the outer edges cool. The2800# /300WHP , truck runs on 315/17 rears and 255/17 fronts. 10.5 and 9 in wide rims. They last as long as 40 hrs and as short as 14rs. The brand matters less so then the size/loading/track conditions..
Considering that, the optimal tire is large and the wheel larger . 245/40/15 are run on 8 or 9in rims. For a SM style/ weight car.
I have no idea how IT would allow wide wheels. and keep them inside the fenders.
I think the right way for IT to use these would be to have a transition year with some weight adjustment for the Hoes and the 200s. I have run the same cars on both tires and the delta is about 6% weight turns out pretty close. ( at 110HP2200#)
Maybe remove 3% from the 200 cars and add 3% for the Hoes. I think the Hossiers will cover the weight even at 6%. But that can be changed or the 200 can be mandated after a year.
