I just purchased my 27 FB. I'm not made of money and will keep the GYM until. I think it's time to replace them. I have purchased a tire pressure monitoring system though. For a 27Fb the max air pressure is 65. Is that the best pressure to run at?

65lbs Cold! I have been running GYM's since my 2005 Safari. Now on my 2014 25fb. One tire failure in all that time and it was probably my fault from hitting a large unmarked pothole. Correct pressure cold and stay under 65 mph and go camping.

Are you running the same pressure in the GYM's as the Michelins?
Also, are you running the same size?

Unless all those things are the same, the temperature differences are meaningless.

I hope you don't think Marathons and Michelins run the same temps.

Man I hate those 'unmarked' potholes. They can ruin your day in a flash, that's for sure. I dislike rough bridge transitions as well.
I really never worry about the 65mph, since I have the 4:10 gears in my Dodge. That is a rarity
They are perfect for 'twisty two lanes' though.
Have a good one !

GYM's have a well earned reputation for blowouts.

Traveling locally and vacations in Texas summers I would monitor them with with tire pressure monitors.

We travel about the country so we sold four GYM's/wheels for $500 and bought four 16" Michelins/wheels for $1500, net cost $1000. Kept the original spare, in the unlikely event we will ever need it, it's fine as a spare.

Because the Michelins are very unlikely to blow out, we seldom travel in hot weather, and I check them at every stop, we don't use a TPMS. Another savings, not a recommendation just what we do.

Our money doesn't grow on trees either and we pay up front for what we buy.

I replaced my 3 yr old GYM's last year. In removing them I found 1 had failed with the beginning of tread separation on the inside ( where it could not be seen). I travel about 10k miles / year. Fortunately it didn't happen under way where considerable damage us frequently the outcome. If you choose to keep them inspect them regularly. You should be able to get a couple of years travel out of them.

My experience with GYM that were less than 3 years old was not good. Had a set on preowned 2009 Casita that I purchased in November 2010. In 2011 one of them started wearing funny while at Glacier Natl Park, cupping on the outside edge. Switched to the spare. No issues getting home. I replaced them with Maxxis ST8008 in early 2012. No issues with these tires. In 2013 we purchased our 2008 Classic 25fb with the original GYM. I immediate replaced them with Michelin LTX (P) 235/75R15 XL including the spare after reading about them in these forums I'm using a TireTraker pressure monitoring system to monitor the tires while towing. I didn't want to take any chances with tire failure.

Do a search on the forum for Goodyear Marathons and you decide if replacement is necessary.

The factory recommends 65 psi on the GoodYear Marathon ST tires they install, which is the maximum pressure printed on the tire sidewall.

The 15" Michelins have a maximum pressure of 50psi printed on their sidewall.

These are two completely different tire designs and ratings, so the tire pressures are tire model specific.

Just like with the 16" Michelin tires we installed, their sidewall maximum pressure is 80 psi. We carry 75 psi which would be too much pressure for the factory 15" GoodYear tires.

The factory installed 14 inch Goodyear Marathon ST215/75R14LRCs on my 2014 23D. They call for 50 psi.

The 15 inch Michelin P235/75R15 108 XL LTX M/S2s call for 50 psi.

Interstateflyer,
I have a 2014 23' FB. I'm thinking about changing out the 14" GYM's with the 15" Michelin P235/75R15's. Do they fit ok in the wheel well? Hows the ride and handling?

Wheel well clearance is about 1". I filed the trim down another 1/2". I don't envision a circumstance where the wells/axle would flex enough or at all to breach the 1 1/2 inches. A friend pointed out that snow could accumulate in the space.....I don't tow in the snow. I had an International 19 with 16 inch Michelins with similar clearances....not problems in 10K miles.

The ride is much better. It seems to track better. Also more braking surface.

You know these Airstreams are not what i would call cheap. Its sad. You would think Airstream management would read this stuff and pull the GYM from service before they see one on the nightly news. Why take any chances with safety. Oh well. I do plan on trying to sell them all tires & wheels.
