Proper tire pressure

[FoDaddy]

we must make positively sure, that the tire pressure on the sidewall is what you place the tire pressure at, no matter what!!

That is incorrect

@mdrl44_173900

his words were very explicit, in his terms that if it said 38p.s.i. on the sidewall, then it’s a must that 38 p.s.i. is followed, and he went on to explain in terms, that this is the main reason of blow outs and underinflation/over inflation when we do not keep the man specs, we can not only void warranty, and will strictly apply.

Again, incorrect. The max pressure on the sidewall is what the tire manufacturer rates the tire for. Not necessarily what the engineers who designed the entire car calls for. If the max tire pressure on sidewall is listed at 38 psi, then that’s what Goodyear/Michelin/Firestone/etc. says the tire can structurally take (plus a safety margin). It does not mean that that the tire should be inflated to 38 psi in all scenarios. If that tire was installed on a car that called for 30 psi on the placard, then the tire should be inflated to 30 psi, not 38 psi. That’s what the manufacturer’s specs calls for in that hypothetical situation.

. this might seem kind of rough, but it was a dealer policy, after this rep left our dealership.So if the sidewall had 50p.s.i. max, it had to be set at 50 p.s.i.

Not only rough, but dangerous, I’m surprised a dealer would willfully take on that kind of liability.

I keep these things I learned top of my list, and actually I have, had better wear from my tires, you name it

Doubtful. Grossly over inflating your tires ( +10 psi over manufacturer’s specs) will result in uneven wear. 3-5 psi over is considered okay in most situations, but going much more over than that isn’t beneficial from a handling or wear perspective.

I will add a caveat to this though. If you’re driving a truck with light truck (not passenger) tires. Then it’s very possible that 50 psi would an appropriate tire pressure if you weren’t carrying a heavy load. LT tires can go upwards of 80psi, but many people will air them down to around 50 when they aren’t carrying a heavy load in favor of a more forgiving ride.
