My coach has been weighed and according to the tire manufacturer's PSI chart, I should be carrying 80 psi. But, when you (or I) have new tires installed, the tire company insists on pressuring up to t...

When we first bought our coach, it had the tires on it from the previous owner. Turns out they were old tires...about 10 years old....that was my fault for not checking date codes. ANYWHO..... Before heading out on our first real trip after buying it, I took it to the local tire shop to make sure that all were properly inflated. Although at the time, I thought they were the experts...but turns out they had no clue and inflated to the plate inside the coach from the manufacturer. Mind you, none of us had a clue WHAT tires were on it when it was new. But, the plate called for 85psi all around. We deflated to that pressure and I took off. I made it to my destination with no problems, but had a blowout on the way home. Not sure if it was the old tires or the underinflation. Fast forward a month, after replacing all the tires with brand new ones...manufacture date codes verified to 2 months before I bought/installed them..... and on the way to our second major trip...and another blowout. Bad tire from the factory, after which Goodyear and my insurance company (Nationwide) made everything good.
Replaced the damaged tire and the one beside it (rear duallys) with brand new Goodyears, had the coach weighed and found that I needed 95psi all around. I now run 100psi and so far...knock wood, I have not had a problem since.
Moral of the story? Know proper tire pressures for your coach and don't trust a local tire shop to just know. You gotta remember....not dissing them, but these guys most likely came off the street looking a job and were taught just enough to be able to plug a tire, dismount and mount new tires on cars and passenger pickup trucks....not 20,000lb RVs. They are not tire experts, nor do they have ready access to the tire inflation charts, nor would they take the time to check them in the first place if they did have access to them. If the sidewall of the tire says 110psi cold, then they are safe in inflating it to 110psi cold.
