Air Compressor Capacity advice requested

I would like to purchase an air compressor with enough capacity to fill a tire to 125 psi. How much rated capacity should the unit have in order to do that? This unit would be carried on-board so physical size is a major consideration. Any specific unit recommendations appreciated.

Before you purchase a seperate compressor are you sure your onboard unit will not do what you need? Are your tires needing that much pressure? Just a couple of things to check before you have to spend more $$$$$.

There is one sears sells real popular on forum egg shaped 150psi works great. I like it better than on board, if I dump air bags I have no air.

Thank you both for those responses We are moving up from a FRED. I have the egg-shaped Sears compressor but didn't think it has the power to air the larger tires and higher pressures of the new unit but I may be mistaken. I will get a hose, air gauge and chuck as well to utilize the on board air. FREDs do not come with on-board air.

Sorry, I didn't know that you had a FRED. I also have the Sears egg shaped compressor and like it alot. Not real heavy or big for that matter. Been using it now for about 7 years. I do believe it will take care of your tire inflation needs.

The Tuscany is not a Fred I have one camping beside me now. The egg shape 150 psi is more than adequate I have 295/80r22.5 tires It tops them off with no problem.

This compressor will do a great job for you....I think it is the one that the other posters are referring to:

We have the Sears "egg" style compressor and it works great. I would also recommend you install quick connectors for your hose & invest in a high quality "in-line" digital gauge & two-way chuck.

I would not waste time on trying to us your Coach air if you really need 125psi? Are you sure you need that much pressure? Your Coach compressor will cut- out around 125-130psi so you'll be right at the max & annoying everyone in the CG while you idle your Coach trying to make it work!

Cheers
