4 Packs Tire Saver Ramps, Prevent Flat Spots Caused by Long Parking, Premium Anti-Slip Flat Tire Prevention Tire Ramps, Quality Portable Handle Design for Easy Movement Suit for Cars RV Camper Trailer

Perfect for my Trailer and Log splitter

The purpose of these makes sense for long-term parking of an RV in helping prevent a near "flat spot" on tires from being parked in one spot (as these give a rounded surface the spread the load). To get these set so all of your tires sit in the perfect spot is very tricky (where I'd say jacking the vehicle up one tire at a time is almost needed to really get each one "perfect" where you can then mark them and add screws into the concrete to hold them). Once you have them set, driving the vehicle onto them seems like driving over speed bumps on the front and back together, but you know when you're in the groove. I'd not use these on gravel or dirt as they are hollow and will sink in (and easily break if too uneven). I noted they mention "oil changes" in the title, yet these don't give even a couple inches rise to make it easier to crawl under the vehicle, so not sure why they added that. So hard to say if these are that great for everyone to go for, but do serve a purpose for some.

works as it should

these will slide all over the place in the garage. I spent a lot of time trying to get my car onto these, but they kept sliding around even when I taped them down. I eventually had to return it after wasting many hours.

At first they look really really cheap but I tell you they are not well built well made and they work perfectly you can use them on concrete tar or grass they are a tire lifesaver.

Perfect for saving those tires for the 2nd garage kept car. No more flat spots

I initially ordered these for our camper, to keep the tires up off of the ground... and I think that they'd work well for that purpose (I'll likely buy another set for that purpose), but I ended up using them to prevent flat spots on my Corvette's tires while it's parked over the winter. These are sturdy plastic, and they're more than strong enough to support my Vette - I suspect that they'd hold up to a much heavier load, such as a camper. The rounded shape fits my tires well, and should help prevent flat spots when the car is parked for a long period of time. Ultimately, these are sturdy and they work well - I'd buy them again. Recommended.

When we park our camper in storage, we have to park it in sandy dirt. I know this isn't good for the tires, so we've had 2"x10" boards that we were parking on. The problem with those was that it was difficult to get them just right on the boards. These tire saver ramps have made things SO much easier, and they should be much better for our tires. All I had to do was get our camper in position, put the ramps behind the tires, and back right over them. And we can feel so much better about the surface that we have the tires sitting on. They're a bit pricey, but worth it for our situation.
