Keep a eye on them lug nuts I just had a wheel come off on my 81 with aluminum wheels. You can bet I am going to keep a closer on them.

What about steel wheels (Rally) with stock steel lug nuts?
That's 80 - right?

Just carefully watch those guys with the air wrenches. They can make over 200 ft lbs, easily. And that much torque may warp your rotors.

I torque the aluminum wheels on all my cars to 90-100 ft-lbs ( I use 100 ft lbs). Have for 30 years and never had a tire come loose or warp the rotors on the C3. Never let anyone attach lug nuts to any wheels with an air gun. Costco, for example, uses the air gun on very slow to attach all the lug nuts and then torques each lug nut individually with a torque wrench with the weight of the car on the wheels.

I do all my wheels (aluminum) at 80 lbs, have for years and never had a problem. It was suggested by a local shop that had worked on Corvettes for years. Drives me nuts when a shop cranks them suckers down to the 200 mentioned above.

On my 2007 Impala with steel wheels the GM dealer did a real job on me when switching from my winter steel wheels to summer alloys. Much too much with the air gun. I had a couple of rusty nuts and wished to replace them afterward. I had an X wrench and could not get them off. Imagine having a flat on the road! I complained and they were re-installed with a torque wrench. You really have to watch these "fast" jobs. Same torque for a Cruze/Impala/4 x 4 Sierra.
