USA Made Extra-Wide Heavy-Duty Flat-Free Tire Ramps with 4 Thick Mats – Prevent Flat Spots During Long-Term Storage – Non-Slip HDPE Ramps Support 10 Tons – for Cars, RVs, Trucks – Set of 4

Works. There is a much more expensive flat stopper with special foam (heard good things about that company) and have to buy 4, instead of buying just 2. I have been skeptical of the flat stopping concept, and decided to take a $60 chance on buying just 2 of these. As I feel the front tires more, I bought only 2. My car sits 7-10 days at a time so I haven’t evaluated over longer sit times. Would recommend trying these first.

PROS:-Extra wide, so they fit our buick's wider tires-We like the separate rubber mats that ensure no slippage when placed under the ramps.CONS:-Some of the ramps have slight warpage; not sure if this will affect performance over time.-Ramps come with strange plastic clips, which we weren't sure what to do with. There were no instructions on how to install the clips.-Surface of ramps look partially melted. Not sure if this will affect performance over time.-Company unresponsive to requests for further information (what the clips were for, warpage concerns)We just started using these to winterize our car. Still need to see how well these hold up.

We are pretty happy with these no flat ramps. They come with the rubber mats to prevent slippage as you drive on to them. These fit 22” tires on an Escalade.
