Changing a flat

Hey Guys,

I'd like some info on gear to change a flat by myself.

Yes I do have roadside assistance but I hate waiting 1 hr for them to get there, then change the tire & write the bill, all in all 1 - 1.5 hrs. And that's in town.

The biggest trouble is breaking the lug nuts. Now I'm trying that with a 4 way. Once, or if, that's done I can change a tire & be on my way in 20 minutes or so.

I do have an extra charged deep cycle battery with a 2000 watt inverter.

I am wondering if a 125 psi, 1.85 scfm compressor with a 1 - 2 gal tank & an impact gun would work to get 8 lugs off. I would power it thru the inverter.

I am not looking to do this on a regular basis. Hoping I never have to.

Another option is a 18 volt battery impact wrench. Or an electric one run thru the inverter.

I am towing a 5th wheel full time & don't have room for a larger compressor.

Any info would be appreciated.

Thanks.

It takes a pretty healthy inverter to power a compressor that can run an impact wrench, like the previous poster said a good cordless electric impact wrench should do the job. Having said that, as long as the lugs are clean and in good condition, and not grossly overtightened they should be relatively easy to break loose. A person who is otherwise capable of moving and lifting a tire the size of your truck's should easily be able to break lugs loose using a 2 foot long bar or wrench.

I've been told to check the torque before every trip. Most 3/8" torque wrenches are at least 18". So if you break the lugs and re-tighten to spec. You won't have an issue with changing a flat on the road.

Electric 1/2" drive Impact, battery powered. DeWalt, Milwaukee or most name brands. Make sure it has enough torque to get the bolts loose.
