As a truck mechanic we were forbidden to use the push in plugs. The theory being that they would allow moisture to get to the steel cords and rust them resulting in the casing being weakened and unusable for recapping. After we removed whatever punctured a tire we drilled out the hole with a special bit, glued in a rubber plug, trimmed off the excess inside and applied a patch and then coated that patch with a sealer.

I called my local RV dealership. They were basically useless. They wouldn't fill my tires on a Saturday because they did not have a technician on duty.

But they recommended a close by truck and trailer supply. The guys there were happy to fill the tires for me. No cost!

Before my next trip I'll look into getting a compressor.

Thanks again for all the terrific tips.

I have read good reviews about the ViAir brand of compressors, and I'm thinking of buying one. They have some (70P, 85P) for about $50 that plug into the cigarette lighter type socket, and some much faster ones (like the 300P, about $150) that clip to the battery. I have two el-cheapo compressors now, and neither one is worth much because they take forever to get anything done.

For about $225, I could get (off ebay) a ViAir on-board compressor bundled with a 2 gallon tank and an air horn. Add a little bit of labor to install that, and it would be both useful and fun. Great for airing up tires after off-roading, and even better when someone cuts me off in traffic.

One thing not mentioned is that some of the booster/battery packs that come with a compressor also have 12V and USB outlets. They are good for charging things while boondocking.

Mike, I'm no compressor expert. We've had this one for 14 years and used it every year and always carry it with us. It's not cheap but small and has been reliable.

Interdynamics HD300 - 12 Volt Truck Air Heavy Duty Portable Compressor - 300 Psi

I'm not sure this is the least expensive source.

The little 12v compressors take a long time to fill a car tire but for a bike, they're great.

I've never timed the compressor I use but I've filled plenty of tires and never noticed it to be slow. Certainly it's not a garage compressor but more than adequate for road use. I've filled at least 6 tires from scratch.

Yup... It seems there is no level ground when it comes to RV dealers. Like you said yours was useless while others go out of their way to accommodate, and please a customer.

Question about tires

Over our 14 years on the road we've plugged at least 6 tires. Every plug worked until the tires end of life. Is their a better approach? Maybe. Though nothing is handier when you're absolutely no where.

I have heard negative comments about them but have never seen them not work.

I only run good tires, also. I'm not saying I wouldn't use those plugs for an emergency, but I wouldn't use it permanently, either. They can dry out and leak, or worse, allow water into the plies and rust the belting. They can also allow air in between the plies and bubble the tire. Sadly, many half-baked tire shops now use them, because they charge the same price and "fix" the tire without taking it off the car, looking for inner damage, or preventing further tire damage.

Like I said, I carry two spares, so I don't have to worry about it until I get home. Once home, it's about a 15-20 minute job to put a rubber patch/plug in to seal it. I do it myself as most tire shops don't hablo ingles, and ram plugs in after you specifically request they don't.

If you want more info, talk to a local retreader. They'll tell you all about rusted belting falling apart while shaving the tire, and it wasn't even from a flat, just something that managed to penetrate to the belting.

The only thing I will put in my tires is a plug/patch one piece combo. If that doesn't work without hitting the sidewall, then my tire is scrap.

My scamp has never had an issue, but one tire is pretty much rated for the entire camper weight. My car trailer runs much closer to max weight, and likes to eat them. I get the heaviest load range e's I can on it, which helped a lot, but it still happens sometimes.
