For tires...all i need is about 85 ft/lbs to tighten it right?

so if i get a impact wrench which delivers up to 350 ft/lb...will that be a better investment then buying a manual torque wrench for basically same price which delivers upto 200 ft/lb?

thanks

 

Impact wrench setting is not as accurate. Impact wrench has a hammering action while it turns. It great for breaking a nut/bolt loose, but not so great for tightening to spec.

 

Stay Away! Stay Away! Using an impact wrench is probably the easiest way to end up with warped rotors. I took my old Mazda to Brake Check to get the pads replaced. When I picked it up - every time I touched the brake pedal - the darn front would vibrate like crazy. Brake Check denied any wrong doing and I didn't know any better. Later the dealer diagnosed it as warped rotors possibly by using an impact wrench. Since then I make sure that any service shop that works on my cars only use an impact wrench to remove the wheel.

When a manufacturer recommends a torque setting for a bolt - I'd stick to it.

 

well that's what im talking about, impact wrench just for removing the wheel.....nothing else.
