I drove my car onto these plastic ramps to change from my summer to winter wheels. I can’t fit a jack underneath without driving onto ramps. After changing the wheels I dropped the car back down onto the ramps and torqued the lugnuts. After that I tried to back up and this happened.

Asking here to know if there is something more to this or simply the ramp didn’t have enough friction on the ground so it slid?

I’m going to jack up the car and put a rubber mat under the ramp later to see if I can drive off.

So weird, this has never happened to me before ! Has this ever happened to anybody else or am I the only unlucky person.

Cheapo plastic ramps not gripping properly by the looks. To be sure jack up that one wheel see if it spins properly.

Seems your wheel locked up and the break is not releasing. I have seen this before when a brake line goes bad. If the inner part of the hose develops a leak. When you put on the break, fluid is forced between the inner and outer part of the hose. The pressure cannot be released, and the brake will lock up.

That made me laugh and yes, it has happened to me. The ramps need better grip or a better surface to get traction. You can add skateboard grip tape to the bottom or other adhseive.

A Few things come to mind for this, The surface where you placed the ramps might not provide enough grip. You might want to check that the area is clean, dry, and free of any substances that could reduce friction. Also the design of the ramps could also play a role. Some ramps have features like rubberised bottoms or anti-slip materials to enhance stability. If your ramps lack these features, adding a rubber mat as you plan to do might help improve traction.

Seriously. The ramp is sliding because the wheel is not freely rolling.
