Tire pressure

I recently purchased a 2007 Tiffin Phaeton 40 QSH. I'M aware the best measure is to weigh the coach at each tire, however until im able to do that can anyone give me a suggested tire pressure for this coach? The tires are 275R70 22.5.

So many variables in your question, Your coach should have a label/decal somewhere on a interior panel, closest, back of door or somewhere stating tire size and recommended pressure as built. You'd be best to use them. No matter what the coach really weighs, as long as you haven't exceeded the maximum weight rating, My advice is run them at that PSI. Invest in a good quality commercial tire gauge.

But no worries, there's a very large group about to descend on this thread with 500 opinions.....ha-ha.....(jokingly)

Mackwrench: you may never have been right in your whole life, but this time you are 100% correct. And most are going to be wrong. The label you are talking about is made for that coach and that coach only! The coach vin is on the label and is for that coach only. The label is usually by the drivers seat on the wall.

I love this support group :-)

But, they nailed it, keep them at rated cold pressure or at least what is on the Manufacturer label for that tire size until you get it weighed. Front and rear weight will get you started.

good starting point. If you load it heavily get it weighed before you go less. I doubt you will have any issues with that as a start
