There's a bunch to choose from; off-road, sports, high end etc - does this choice actually effect the driving/control of a car, or is it purely aesthetic?
I believe I read in one of the more recent patch notes that Rockstar had changed the traction on cars without spoilers, so that a spoiler is needed if you want better traction. I found that out the hard way from driving the Massacaro without one (I like the look of it without, though since whatever patch that was, I've needed to put a spoiler on).
I'm just curious as to whether tyres make any difference. If I were to stick off-road tyres on a sports car, would that sports car perform better off-road? If I were to slap sports tyres on a Sedan, would that car then be quicker/have more traction?
