110 PSI Air While on the Road

[otrfun]

Thinking about upgrading from 80 PSI E-rated tires to 110 PSI G-rated tires.

I assume 110 PSI air is available at most Love, Pilot-type truck stops?

Anybody use a portable air compressor? If so, what make/model?

If you are heated up and below "MAX" pressure you have a tire problem.

Well that first sentence depends on your definition of "wildly" I guess. Under similar conditions, the pressure should be similar.

And I don't think I agree with that second sentence at all.....but not sure what you are trying to say.

Conditions vary as a person could be traveling in freezing or 100 weather the tire themps will vary "A LOT".

If traveling on a 100 degree day and your tire reads 80 psi and that is it's max the tire could easily have only 40psi cold and may have a hole or ?????

Really, who checks their tires HOT??????

I've had a Power Tank for several years. Very happy with it.

I have the 15# model. In retrospect the 10# would have been more than adequate.

Power Tank is expensive but here's a link to PT, which has good info, applications, etc. -

Power Tank

This "DIY" info is available on many off-road forums.

Although this thread (w/pics & info) on the Jeep forum is from 2011, most of the links provided are still active.

BTW - a couple of years ago) I spent *less* than the costs stated in the thread (which was considerably less than Power Tank)........

Jeep Forum: "Build Your Own C02 Tank System - High Quality & Lowest Cost"

Benefits:
*NO* waiting to build and/or maintain desired pressure.

*NO* electrical connection required.

Easily take it where you need it.

BEST of all........SILENT !!..:C

While my 12v MV-50 rated 150 psi may take its time I also think it would work fine in a pinch.
Yes regular maintenance I would be looking for more power.

I have a latch on air chuck that makes airing up tires with a low volume compressor like my cheapie pancake one. Took 5 to 10 minutes each to air up the trucks rear tires from 50 to 75 this morning to haul some concrete wall blocks. To our RV lot.

We just went from LRE tired trailer to a LRG tired one. I have ordered a new digital pressure gauge and will have to think about a better portable compressor.

True but if they are HOT and below your target COLD pressure, you know that they need some air. And pumping them up to your cold target is better than leaving them even lower. Going +5 would be even better.

If you have checked them hot a few times before, then you should know what is "normal" for those conditions.

A lot of campgrounds have air available. Best to carry a way to pressurize your own tires.

I have never checked my pressures hot until looking at my built in monitoring system on my truck.

I don't think I would bother with carrying a compressor that can reach 120psi. Every one that has been mentioned will be so slow that you won't want to use it. I carry a Harbor Freight pancake compressor. It is capable of over 100psi. And it runs pretty good. I used it to nail down 500sq/ft of hardwood flooring recently, just because it was easier than stringing hose from my shop compressor. To use it on the road I would have to dig out the generator, dig out the compressor, and then wait forever for it to top up a tire. I figure that would be okay in an emergency, to limp to town for example. I guess I'm just saying that you won't find it very convenient. And you can limp to town on 80psi.

If you do get a compressor, make sure you equip it with a fitting that will snap onto a tire stem. Because you're going to be connected for a long time, and you won't want to be kneeling and holding the chuck for an hour.

In 50+ years of RVing I have found very few places that did not have compressors capable of 110 psi., even ones that require quarters.
If the tires and rims are rated to do so there is absolutely no reason not to. P
My tires and rims have that rating but I run at 100 lbs., simply because I choose to do so. At 110psi. the ride became harsher than I like, and any lower than 100psi. I experienced what I call squirm ( a tendency to follow ruts ).
As to compressors, I also have a Porter Cable pancake.

PS; I would like to believe everyone that has been driving a vehicle for any length of time has the common sense not to exceed the maximum rating, but according to one poster there must be some.

Since most big rig tires run at 110-120 PSI any truck stop should be good. Never seen one that didn't have adequate air.

I have the Sailuns and have not added air since I mounted them over a year ago. Good tire IMHO.

There are 12V D.C. compressors that will do the job - Google will generate results. The downside is that these are expensive: $250 - $500.

I only need 80 psi so I got the smaller model ($250). Works great. Takes truck tire from 50 psi to 80 psi in a minute or two. Takes me more time to move from tire to tire than anything else when touching up.

Or carry air tank.

I have used a 6 gal porter cable pancake comp for years to air up my g614,s to 110psi.Have you ever tried to get a big rig close to a tire shop when you need air,what a pain.

Just because the "tougher" tires you are buying allow for pressures up to 110 lbs does NOT mean that you should put that much in them.

In fact, you probably should NOT DO THAT and use close to the original recommended pressures if the load has not changed.

I personally think that getting good name brand tires is more important that putting on ones that are WAY over-rated for your application.

85psi is where he most likely should run them. I did the same and had great wear with many thousands of miles.

Use the weight/inflation chart and add 5psi. Per GY Tech Support when up sizing load range.
