Aftermarket wheel torque
 

I purchased American Racing ATX artillery rims and put them on my truck myself. Per instructions torqued to factory specs of 150-165. Recently had new tires installed by a local off-road shop and they torqued them to 115ft lbs because they stated that the aftermarket rim has a conical seat and will damage the rim if it's torqued to the factory value. Thoughts?

How does the seat look now? You can pull a lug nut off and examine it.

If you damaged it the first time you put them on you should see the taper all gouged of deformed

Rims look fine. And have for the last 4 rotations. I also called wheel pros the maufacturer of the rims and they stated use factory specs. So I'll be going out and re-torquing to factory.

Was it 4 Wheel Parts? They did the same thing to me years ago. I have been running factory specs without any issues.

are the lugs rated for the proposed torques?

If you mean lug nuts, I believe so. Tirerack knows what vehicle they're sold for and they've been holding for the last 6 months no issues. If you mean the lugs on the truck they better be they're factory and for 12 years they've been on that tight.

No. It was a mom and pop place.

If the manufacturer says go with factory specs then I would stick with that since it has been working for you so far.
