i want to get an air impact wrench to change my tires with.?

Never use a an air impact wrench on the lug nuts of a vehicle when you tighten them. Use a standard lug wrench instead and run them in until they bottom out, then torque them to factory specs using a torque wrench. When using the torque wrench, torque the lug nuts in a pattern as if you were drawing a star if it 5 lug and as if you were writing the number "4" if it is 4 lug. Always torque the lugs to spec in increments of 1/4 torque at a time until the torque spec is reached. This ensures that the brake rotors and wheels are not warped in the process. I have seen too many cars with warped brake rotors and wheels due to some tire shops using impact wrenches to tighten the lug nuts.

Air Torque Wrench

I take tires off of f-350s with my 3/8 impact just to prove it will. (snapon mg325) but you probably want an IR 1/2inch. they make pretty good air tools. You should probably get a good torque wrench too. Remember if it is a "click" type torque wrench always dial it back down before putting it away. Now since you seem to be talking air tools if you are ever in the market for an air ratchet there is only one way to go. Mac ar1776

The biggest concern you'll have when using air tools that use a lot of air such as a torque wrench is the volume of air being supplied to the wrench.

For best results, I recommend that you get set up with a 5 HP, 220V compressor with about a 60+ gallon tank.

This set up will give you enough air to power most any air tools you'll ever need without having to wait forever for the compressor to recharge the air tank.

Regarding the wrench, a 1/3" drive is likely to be more than adequate for 99.9% your needs.

Don't both with any of the smaller compressors if you wish to use it for body work or painting either, since those activities also require tools that consume a large volume of air to adequately power them.

You need a 1/2 inch, get one with a lot of reverse torque. Ingersol Rand usually makes good air tools.

1/2" is usually plenty enough depending on the tool itself. My weapon of choice is the Snap-on MG725 which is pricey at $459.00, but there are more options such as Ingersoll Rand, Aircat, or even a Craftsman from Sears for $110.00 and delivers 580 ft-lbs of torque which is plenty.

Any recommendations for reverse torque? I want to do my own service on Ford F550 s...Does anyone know torque specs for Ford F550 19.5 wheels?

Sad News: Howard M. Hurd, one of the most respected patriarchs in the NASCAR Winston Cup Series garage area, died today at the age of 89. His development of special high-speed air impact guns - the tools crews use to change four tires in less than 20 seconds during pit stops - earned him recognition as the father of today's lightening quick pit stops. Hurd became a prominent figure in NASCAR racing during the early 60's when NASCAR legend Glen Wood's Wood Brothers racing team first tested his modified 405 Ingersoll-Rand air gun at Atlanta International Raceway. The Wood Brother's success in the pits lead other teams to follow suit and the demand for his air guns made Hurd a household name in the NASCAR garage. His highly modified yellow and black air gun set the "norm" for pit stops. In the mid 60's Mr. Hurd also worked with NASCAR official Bill Gazaway to develop a device to check the stock car body's style and height. Together, they designed the original template used to measure the outline of a stockcar. That template is still used today at every NASCAR Winston Cup weekend to ensure a level playing field for Sunday's race. In 1982 Howard Hurd received the Buddy Shuman Memorial Trophy, given each year for "outstanding contributions and loyalty to auto racing". The trophy was presented to Hurd at the NASCAR Winston Cup Awards Banquet in New York City. The Hurd family continues their involvement in racing today. 2000 marks Hurd Pit Tools & Equipment, Inc.'s 41st year in the business. The company's reputation for service and dependability is highlighted by the fact that since """1961""" every Winston Cup championship team has relied on Hurd designed impact wrenches during pit stops. Howard's grandson James, 32, runs the day-to-day operations of the company and has followed in his grandfather's footsteps by modifying the airflow of the 405 impact wrench. This newly designed "Thunder Gun" provides increased power, speed, and practicality. The yellow and black Thunder Gun is also on display at the Daytona USA. NASCAR fans can experience the thrill of "the fastest gun aro

Half-inch drive is sufficient....and don't hammer the lugs home.......stop short and torque the lugs down if you have alloy wheels.
