OK, guys. Here's the deal. My friend has a new Camry similar to my 2013 Camry. HE is obsese (just a fact which he told me to ask about) and has experienced more inner tire wear on his driver's front side especially and also the drivers rear as well since he rotates only front to back. COULD this REALLY be partly due to his weight!? I checked with a frame shop since he is disabled and not a car guy. The frame shop says the Camry has a 150 pounds factory allignment spec driver design factored into the design and that most shops do not even have a person in the drivers seat applying ANY weight at all during alignment. So in summary they say he may be getting a car that is within spec on the rack with no weight in the drivers seat but when he, being 300lbs gets in..... that it CAN cause a change in the car's "set" and cause more driver front inner wear, especially since the gas tank runs 70% volume on the driver's side of the car ALSO. Especially since he drives it alone every day as he is single and he travels highway miles and curves in the hilly region of our state. My mind is blown! Your thoughts? MODS , if this is more about repair being alignment stuff, please do move it to the maintenance section.
