I should probably make sure I get my car aligned...
Yes, excessive camber, toe, tire pressure, driving style, etc., alone can unevenly wear tires. Two or more of these causes together make the effect exponentially worse.
Considering the one shop and one person that we all trust to do the alignments on our cars is the only one that's touched mine, and aside from the rear strut slotted hole popping during the afternoon session of the Mother's Day event, the alignment is "perfect" = 3.2* front, 2.6* rear, 0 cross camber, 0 toe, 0 cross toe, approx. 4* caster (GC camber plates maxed without rotating). Alignment is not an issue. Tire pressures are spot on at 36lbs all around (remember, street/daily set), and not an issue.
Yes, I experience slightly accelerated tire wear from camber. Yes, I experience slightly accelerated tire wear from driving like an asshat. No, I do not believe that either of these reason a change of setting/behavior.
All the bs aside, I'm poor, and would rather be an idiot and get cheap tires that I can afford that fill my needs than cry about not being able to afford something I can't afford, and end up with expensive tires that wear just as fast as the cheap tires, and cry about the fact that I just burnt through a set of tires that I couldn't afford.
I have, of course, given this no thought whatsoever, and am haphazardly attempting to find crap tires because I like to buy all the crap parts I can.
With all that said, I'm trying to find a reason to not sell everything I have in order to buy two sets of 17x9 RPF1s.
