Race Ramps RR-FS-10 10" Wide Flatstopper (Set of Four), Tire Flat Spot Prevention for Vehicle Storage, Tire Saver Ramps, High-Density Foam

Light weight and easy to manage and place. A little awkward to pull up onto, you need to develop a system. Once you do it's simple.

Used jack stands prior and was skeptical of performance. These didn’t flat spot over 4 cold months on summer performance tires

I have been using these for almost a full year now, on the outside, exposed to inclement weather, heat and cold. So far they have held extremely well. No problems, no issues. DO NOT BUY THE YELLOW ONES! You will lose your money. They will break, slip and will roll out from under your car every time you try to use them. I know since I fell for it...I use these tire savers on a vehicle that I keep outside. It sits there for about 6 to 8 weeks at a time. My previous "yellow" hard plastic ones disintegrated in one year and would slip out when loading the car. This is the first time I used these. Asphalt was wet so I was not sure how easy it would be to load, but the car went right up. Ramps did not move, it was effortless. I hope they can take the elements, but they look sturdy enough. I'll review again after 6 months of use.UPDATE: After many months of use outside, I have to say that these are working great! Still like new, car goes up and down in any weather without them slipping out and they have kept the tires from developing flat spots. Worth the money!

Granted, there are far cheaper models on the market for flatstoppers, but as I tell all of my friends and family, you get what you pay for.These are worth the money in my view and experience. They are 28” in overall length which allows plenty of distance and grip for the tires so you can easily drive on and off of them. One of my friend’s thought he’d save himself huge amounts of money on a set that was under $50...turns out those were so short (less than 14”in total length) that made them nothing but sling shots for the tires. He’s never been able to drive onto them in 8 attempts, thus deemed them garbage, unless you want to use a floor jack to raise each wheel in order to place them under the tires. They were so mangled and marked up after 8 failed attempts to drive onto them that we wasn’t even certain he was going to be able to return them as unusable. I’m very pleased with these and look forward to many many years of using them

I was a bit surprised when I first got these, that they are a dense plastic, not dense rubber. Maybe that detail is written in the description, but it escaped me. I don’t care how “lightweight” they are, but was hoping a rubber compound would assist in stopping flat spots, but this design relies solely on cradling. They also slip & MOVE a bit once the car falls over the first lip & down into final cradle, which in turn changes the cars final location in my garage stall (not good for me). So instead, to ensure the car is exactly where I want it, I have to do final parking first, then jack it up & place these under each tire. pia. But they work (expensive), so I’ll keep them.

I shopped around 18 months ago for what I hoped would be the best anti-flat-spot storage ramps. I have a Genesis G-70 Sport 3.3T with soft summer tires and store it away for the winter months, Mid-November through mid-March. I did NOT want to have to deal with flat spots in the Spring. I chose these based on the Reviews, and I'm SO glad I did. They are IMO the absolutely best anti-flat-stop ramps you can buy. They're low to the ground, very well made/sturdy, very light, very easy to use, and they do prevent flat spots. Yes, they're not cheap, but they're really well made so I was willing to pay a bit more for them compared to the cheaper, less effective competition. Just put one Flatstopper in front of each wheel, and easily (and slowly) drive up the ramps until each tire is nestled into the gently scooped base. I just used them again this past weekend. So easy and quick.They're awesome!

This product is made of STYROFOAM! I had thought I could attach it to my garage floor and drive onto it, but doing so would crush edge where I drove off. It must be place in front of the wheels each time you want to use it.Not durable, not sturdy, and certainly not worth the $200 they get for it!They did not ship it on time, and their delay meant it arrived after I had left for two months. Even though Amazon issued me a Return Authorization, RaceRamps would not accept it, citing an inflexible 30 day return policy. It was THEIR FAULT.DO NOT WASTE YOUR MONEY WITH THIS COMPANY'S PRODUCTS

My Grandson uses them, he’s happy
