Can I use a Quik Jack, jack, jackstands, etc. on top of these tiles? I do a fair amount of work on my vehicles in my garage.

Hard plastic tiles are not recommended for installation with the use of car jacks or or any lift similar to this directly on top of them. These tiles can be damaged under the weight of a car jack. We recommend using your car jack directly on concrete or place a plywood board or steel plate under the jack.
