At our local tracks we only run the BSR tires just so the LHS don't have to carry both brands. A few years ago during the yellow stripe tires people thought one brand was better than the other so the LHS loaded up on that brand and ended up stuck with them when everyone went back to the other brand. So it"s just to keep our LHS from having to carry more than one brand.Is there any difference between the Tm and BSR world gt tires? Same duro reading, purple strip, just different wheels. I know everybody says BSR tires per their rules, is it only because they were the only tires available when the rules were written?
For us we liked the BSR rims better than the TM's.I have heard persons say one brand is faster than the other, I prefer T.M. I have tried a set of BSR's for grins. My truck ran the same lap times on both brands of World GT Tires, so I guess it's preference in this situation.
