2007 Lexus RX 350 - Swollen lugs

Same as above. My car has 193k miles and when mechanic rotated tires he told me lug nuts swollen . I am wondering if he didn’t even use the wrench/socketvthat came with the car or if this is legit.

The spare tire wrench is not a suitable tool for vehicle maintenance, a professional 21 mm socket is of much greater quality.

Your lug nuts have rust damage or they were damaged by your tire shop using a 7/8" socket instead of a 21 mm.

Common problem on several brands.

This seems easy enough to check. Can you get the wrench onto the nuts or not?


It’s true on certain vehicles.

I call them lug nuts with condoms.
