Obviously the tire material / tread / etc matters a lot, but in general, is a 275mm wide tire enough get get traction? They will be street tires on an entirely street-driven car. I do not want to relocate the leaf springs if I do not have to; 275's are the widest I can fit in the stock wheel well.

'73 Dodge Challenger

Thanks!
