Remembering manufacturers TW are not the same...........
Current rules say R's a lone are a bumppete
once used a TW ~160 tire finding them just as grippy as R's, just more life.
As such, if the average TW for a street set of tires is ~350. and most performance tires are < 200.
Is it safe to say some penalty should be incurred?
Or should streetshod cars have that distinct disadvantage knowing that tires are the most beneficial mod that can be made, while being so meticulous with all else?
