Our 05/06 LTV is supposed to have 62 front (Wally has changed the front up a bit) and 79 rear. All 4 of mine are 79-80! I asked the dealer and he said they inflate per what is on the tire. He said several tire stores told them that a very low front presure will cause wear on sidewalls and the tire was designed for what is on the tire. Is that what you all do? We are going to a park about 200 miles away this Sunday and want the correct presure.
TIA

MP, the dealer's an ... idiot (kindest word I can think of). The sidewall is labelled something like "max load xxxx lbs at 80 psi". That's just the maximums for the _tire_, and says _nothing_ about your vehicle. Go with the RV maker.
BTW, I've tinkered with cars for about 40 years, and I've never heard of 'sidewall wear'... somebody's either blowin' smoke, or smokin' something.

I will call LTV tomorrow and see what they say. I think I agree with you, Handbasket! However, both Les Schwab and Americas Tire told us the same at different times.
Also, these are 225/75 R16 LTX A/S Tires

Well I have 19.5 and the manufacture label says 75 lbs on a MH P-30 frame, the replacement tires Max are 110 lbs and the rims are max at 95 lbs. So the tire shop set the new tire pressure to 90 lbs front and 95 lbs on the back duals. A lot of rigs have upgraded tires with heavier load range and require higher air pressure than what's on the vehicle label. Low pressure over time will damage tire sidewalls.

I don't have a Camping Van, but in all my vehicles I use the pressure recommended by the tire manufacturer for the ACTUAL MEASURED weight on the tire (using the highest pressure on a per axle basis). Works for me.

I don't recall seeing anyone ever report needing that much pressure in the front.
I usually shoot for 55 to 65 in the front and 75 to 80 in the rear on all of my one ton chassis B's with load range E tires....
I woulda thought LTV would have a sticker in the door or somewhere's, as well as in the manual.

Problems caused by under inflation
Surveys by tire service engineers show that at least 25 per cent of all tires examined are under inflated by more than 10 per cent. Under inflation is one of the main reasons for rapid shoulder wear, uneven tread wear and premature tire failure. But take care; overinflation may also result in inferior handling, excessive tire wear and premature failure.

I run with 75# front and 80# rear, have done so in all three of my PW's, rides a tad rough on the pot holes, but handling is much better than a soft ride.

Well, I called Michelin and they said that the Manufacturer should know the weight distro. So, if LTV said 62 in front and 79 in rear then THAT is what I should use! In NO case should the tires be filled to what is on the sidewall. Good info!
