Yes I would never get under a car with jack stands, I had a bad experience before where I was young and used old old jack stands and one actually starting cracking while I was under the car. yeah, scary. Had I not realized it then it would've definately came crashing down.

I need my rear jacked up so I can remove both tires at the same time. A local shop (that I actually trust) says they won't put 295's on my stock rims and then let me drive away for legal reasons. I need to bring them just the rims and tires.

I'm thinking maybe Ill just buy nice hydraulic jacks and leave those under each side. They should hold for a few hours? Probably....
