I have a regular not too heavy honda accord. When trying to carefully drive up these ramps, they simply get pushed forward. I tried putting my foot on the break while accelerating, but still no luck. They seem to be too light to actually create friction between the floor and the ramps.The so called rubber feet dont work, they get simply pressed or torn after a just a couple of uses. The surface on these ramps is almost completely smooth, no traction whatsoever.You are better off buying the original old fashioned metal ramps. They never fail and are stronger and heavier. I found a couple of the metal ramps on craigs for a fraction of the cost, and in perfect condition.DO NOT BUY THESE!

Bought these for my Vette. The length of the ramp is not sufficient to get the car on and off without using wood extensions. Getting on is OK, but getting off without the wood slipping and crashing the bumper is a real trick. Have to bore a small hole in the wood and a small hole in the ramp to "lock the wood extension into place" to avoid slippage.Other than that, they work.

Total waste of money. Just slides as you try to go up on it. May as some here say work ok with light cars with skinny tires. I dont know. But, I do know if you have wide tires and a heavy car forget it.

I bought these ramps so I could get under my Firebird, the metal ramps are too steep. So far the Rhino Ramps have performed great, even though they could be a little more sturdy. I haven't had any of the sliding problems mentioned above, but I also use mine mostly on grass. You could probably buy a nonslip rubber mat to put under them to keep them from sliding on concrete. For $35 I can't complain too much.

Bought a set of these for doing the oilchanges on the family cars over the weekend. They work great on cars with lower ground clearance, and are easy to set up and store. Much simpler than having to get the car up on jacks or blocks. RWD cars may have a bit more trouble getting up these if they're used on surfaces with lower traction, but FWD (and 4WD/AWD) cars will get up them just fine.

These things are not at all safe. They may work out on dirt, but if you try to use them on a concrete floor, raising the front of a rear wheel drive vehicle (or the rear of a front drive), they shoot out from under the wheels and become lethal projectiles. One of them actually put a huge dent in the front of my Snap-On roll around and it would have surely shattered the ankle of anyone it had hit. I have a set of these plastic POS's and won't even give them away for fear of them injuring someone. Go for a good set of welded angle iron ramps and stay FAR, FAR away from these killers.
