PSI
Most coach owners don't check the "PSI" in there tires daily. In fact many owners don't do a walk around before starting their trip.
New (old) Tires very good question. Cheap is cheap as cheap is cheap, you get just what you pay for. Just because the sign outside the store says "Goodyear" or "Camping World" dosen't mean your buying the best tire. All tires start to dry rot from the day they are made. For the most part Goodyear, Michelin, Firestone, Bridgestone and Toyo tires are good tires but, that is if you take care of them. Back a few years ago I was in the trucking business and I have bought hundreds of tires over those years. One of the first things we told our drivers is "Check those tires before you start your trip". It doesn't matter to much the brand name of your tire you can have a blow-out any time. However, if you check your tires every day the chances of having a blow-out or a flat tire becomes less. One should always remember that piece of 'Rubber" you are riding on is the only safety you have for a good trip or a deadly trip. If you have a 'Blow-out' on the front at 65mph you will lose control and you may kill someone and the tire dealer will not care. Have a good day.
