Tire not holding pressure

[cameronpatentla]

Our new 2016 Winnebago ERA 70X has Continental Vanco 4Seasons tires. The front tires are supposed to be at 60 psi. The left front has had no problem maintaining that pressure, but since we bought the unit last month from McClain's RV in Denton, Texas, the right hand front tire has had to be re-inflated a couple of times to get it from about 40 psi back to 60 psi. Just now, after a 300 mile trip over the weekend, where both fronts started at 60 psi cold, now the left front is still at 60 psi cold, but the right front is back down to 40 psi. Other than the obvious answer that the tire is not holding its pressure, any ideas on what could be causing this (e.g., warped rim, etc.) Has anyone else experienced this with a new MH? Thanks, Mike

I had the same issue with my ERA with chrome wheels it was the cheap valve cap would screw down too far let out air. I noticed the new ones on lots have regular caps.

Thanks Bob. I'll try them before I make the 30 mile trip to Denton. To those suggesting Les Schwab, unfortunately, we do not have them here in North Texas. I had a flat in a rental car in Seattle some years ago, limped into Les Schwab, and they patched it for free. So, here's a shout out to those in the Pacific NW. Go to Les for all your tire needs (FYI to my fan who likes to report me to the moderator from time to time, the foregoing is not an advertisement for Les Schwab--just a testimonial ;)).

Les Schwab was where I went to (for my car). They were fantastic.

Good Year stores sell passanger car tires. You need to go to a truck stop and have them check it. They are equipped to handle your MH. Or hit up LesSchwab tire store.

Just got back from NTB and Goodyear. Neither one had a lift that could raise 11,3000 pounds. Both of them said to take it to an RV dealer. The guy at Goodyear suggested running Windex around the rim to see if there is a broken seal between tire and rim (did, looks fine). He also said chrome rims are notorious for developing miniscule cracks. Heads up, McClain's RV.

tire shop does not have a jack:h

Not just any RV dealer but the one you bought it from.

Brand new vehicle: USE the warranty that it came with.

Valve stem. What kind do you have?

If this was on your car what would you do :H

GO to a tire shop and get it fixed.

Discount Tires fixed a leaker on my truck for FREE and I hadn't been a prior customer........am now!

Thanks for all the quick, and helpful responses. I'm off to NTW now! These forums have the best audience. Cheers, Mike

Go to a good tire store and have them remove the tire and check for slow leak, probably a nail hole like pointed out above. If so, the repair is relatively simple and inexpensive; definitely get it taken care of real soon!

[donn0128]

Nail, screw or something in the tire. Valve stem bad, loose valve core. As a last option a cracked wheel. You really need to take it to a qualified tire store and have them do a leak test. Could be simple, then again it could be serious.
