It depends on the tire. Ride comfort was mentioned before and that's a big part of it. Tires are far superior than they were back in the day and are much less sensitive to changes in pressure. But I wouldn't recommend going much over 10% over your maximum sidewall pressure. Definitely not 50 psi. Overinflated tires can still be victims of uneven wear but it is a problem with wider tires that require the steel belts in them to be flatter than the little donuts that most people like to run on this site. My little 175/70r13s are not very susceptible to that where a 255 in a truck tire will be able to bow out in the center easier. Keep them inflated but not too high. Don't ever let them get low. That's free gas you're wasting.
