Want to rent: Rear wheels and tires (SoCal)

Imperial

I want to get my rear wheels widened but in order to do so I need loaner rear wheels & tires to replace my current wheels so they can get worked on. I can use my spare for one side but would still need one more although I would prefer to loan both rear wheels. Would there be anybody in the SoCal area willing to loan or rent me their rear wheels for this purpose? Condition of the wheels is not an issue although I would need a decent amount of tread left in the tires to drive the car to and from the wheel shop obviously. Otherwise the car would be parked for the period of time it takes to get my rear wheels back.

Thanks for your consideration. =)
