Tire Pressure

Be never been able to find anything concerning 'recommended ' tire pressure for my Airstream. What guidelines do others follow?
Thanks, Derek

The proper way to do it is to measure temperatures of the tire on the middle and about an inch from each side. Best to do this with an IR thermometer. If you are hot in the middle too much pressure. Hot on edges then too little pressure. I would start at the max pressure on the tire and work down from there. Another way is to use a chalk mark across the tire and drive a few feet. The same principle applies here. If the chalk mark is lighter in the center you have too much pressure.

Thanks Perry. Guess a trip to Harbor Freight is in order. Need to look at max pressure on tires to be sure I'm at least withing 10lbs of max pressure.
Anyone seen what's recommended for Chevy P-30 chassis?
Thanks, Derek

Changes by tire manufacturer, correct way is to weigh each wheel, average for axle and use pressure on their chart. My tire dealer said he always fills to max, but his usual customers for 19.5 are tow trucks. He didn't know number to use so a told him to set at 80 and I will use the method by Perry above.

I'm about to head outside with my puppy. I'll see if I can spot max air pressure on my Michelins.
Thanks, Derek

110psi, cold max tire pressure. Noticed when I looked, that there are separate weight ratings for use as a single tire, or on a dual. Interesting, the dual weight rating was lower.
Thanks, Derek

I don't know the specifics on your three axle 34.5 but my 280 runs between 65 and 70 psi. It's interesting that watching my TPMS the tires gain about 10 psi. in just a few miles of travel. The inner duals also run a little hotter if you use the brakes a little. The tires on the sunny side also run a little hotter. Checking pressure on a hot sunny day also will give you some interesting results. What you read on your gauge while you are parked in the morning isn't what your tires see riding down the highway.

Cheers, Dan

Have you tried to get an owners manual from Airstream? Well worth the money. Is there a sticker somewhere on the coach by the drivers seat for tire pressures. Underinflated and they come apart, over inflated and handling can change as well as beating up your suspension. I had a 35 motorhome that called for 90 psi another friend had an earlier one and his called for 70 psi, suspension difference from Ford to Workhorse, same brand and size tires.

Go to the tire OEM site and they will have a chart for inflation pressure/Weight.
Take your unit, with a normal camping load, and have it weighed on a truck scale, wheel be wheel, and axle by axle.
Follow the OEM tire recommendations

There seems to be a lot of best ways posted here. However this (masseyfarm's) post is the one that I believe you will find to be the safest, easiest and most trouble free.

The manufacturer knows the design and capabilities of the tire much better that Joe Blow Salesman at the local gas station or tire dealership.

Will scour the driver's area for a label concerning 'recommended' tire pressure. Now that I think about it, I DO have an owner's manual in the Airstream, but don't remember seeing tire pressure recommendations anywhere. Time to pull it out again and peruse.
Thanks, Derek

when I was running a P-30 chassis RV, tires at the max side wall was the rule...

Flats and dry cracking was the end of a tire well before tread wear...103,000 miles when Katrina ate it up.

In hind sight...a better chance of loosing your RV to a hurricane than a tire failure

One less thing to obsess over

I was told by a Goodyear Tire representative, 6 years MAX for use of any tire, passenger car, or RV.
To be honest, my Airstream won't be leaving the county until I have a complete set of 8 new tires. Have too much invested in my dream Airstream to go 'on the cheap' with not buying tires.
NOT going to be like someone I know who says he's driving on his tires until the blow. Let's face it, a blow-out can do substantial damage to our Airstreams. I'm just not going to take that chance.
This is a lifetime dream of mine, will be a short-distance camper until new tires are in the budget.
Thanks, Derek

If you keep it indoors away from the sun and heat they will last a lot longer.

no space in my garage for a 34.5 foot long motorhome. At some point, I plan on moving into my AS motorhome, and drive, drive, drive. Maybe I'll get some serious use out of the tires then, but until that day arrives, the AS will be parked in my back driveway, just waiting for it's Sunday afternoon drive to blow out the cobwebs!
Thanks, Derek

Sounds like a long time to me. Life expectancy I have heard starts at about 5 years.

...............................
When statements like this are made, I find it valuable to consider what vested interest the person making the statement may have.
In this case its fairly obvious.

My entire life, I have replaced tires only when they show signs of needing to be replaced. The secret is to check them frequently and to know what those signs are.

The only blowout or other catastrophic tire failure I have experienced in 52 years of driving was due to my own negligence. I put off repairing a slow leak in in one of my SOBs 4 tires, thinking I could have it done when I got home.
