I know what you're saying about the manufacturer recommended tire pressure, but there's variables in the vehicle weight and suspension setup that make their pressure range relatively meaningless, in my view.
Engineers test things before they go into production, with a given tire, at a given pressure. They suddenly decided to bump up the pressures to 36 in last 2 years on our new vehicles, after all those years of 33 front / 32 rear.
I'm not buying it....I say they have their CAFE standards they want to achieve, as well as keep a customer happy by advertising higher MPG's. So simple solution - bump up tire pressures and waaa-laaa...instant + 2.2 MPG...whoop-te-F'n-do.
Meanwhile they damn well know the tires will wear faster at higher pressures, but they don't care because again, they sell more tires! Dumb customer doesn't think twice, what's $900 when you pay $40-$50K for a vehicle.
I'm to believe that great strides have been made in engineering tech of tires, tires that are used on MULTIPLE vehicles and multiple makes, to suddenly get the same wear, at higher PSI?
Margins are so low on tires, they're commodities, so they aren't spending millions on R&D to invent the space shuttle of tires, with super advanced tech. I ain't buyin' - sounds like you swallowed a load of scat?
Talk to me in a few years when they change back to 32 PSI, with all the customer market complaints about rough rides and poor tire wear.
You need to think ulterior motive with these people and be a critic. Look at Volkswagen TDI diesel scandal for how they do nefarious things to manipulate the public.
Weren't you the guy talking about rolling over into the woods, off freeways while pulling a trailer? Probably your over-inflated, hard tires, with no grip on the road. But I digress.
I've never rolled a trailer or had an accident pulling one, but then again, I haven't done so (routinely) since 2003 so probably not one to judge.
