tires

Any suggestion on PSI of tires. I keep loosing PSI in rear tires. Tires are in great shape. Very slow lost but annoying. These are on a 2002 Gulf Stream Conquest C. :idea:

Don't know specifics on the recommended pressures for your particular coach, but there should be a nameplate somewhere that show the factory pressures. Have you weighed the coach on a per-axle basis? You need to meet both the axle weight ratings as well as the vehicle weight ratings simultaneously to not overly stress the tires.

Another thing is that you mention your coach is a 2002 model so it likely came with tires with a 2001 date code...and those should have been replaced no later than 2009 regardless of miles or tread depth. You mention "great shape" but the real key is the DOT code on the sidewall which gives the date of manufacture. The second set would therefore have another 7 years on them now at least and be up for replacement as well. Perhaps the sidewalls (maybe inside where you can't see them very well...) are seeping air a bit. Again, the date code is the determining factor as to when to replace your tires.

Your safety is very important, so never operate a vehicle as heavy as your coach on old tires. There are many articles on this site and elsewhere on the web about tire casing aging and recommended limits.

I have to agree with Chuck, I just chunked 5 tires that had excellent tread on them due to their age. They just turned 8 years old and we had one blow out on us so to make sure this camping season is a good one I replaced the 5 that were old. Why just 5 tires and not 6? Well, on the way home to NC from Daytona after Thanksgiving we had one blow out so we got to spend 2 1/2 hours on the side of the interstate waiting on road side service on a Sunday afternoon, not a fun way to end a vacation and the other 280 miles home after the blow out wasn't nerve racking just waiting on another one to let go, luckily it didn't. Its better to be safe than sorry. ;)
