MAXSA 37353 Park Right Tire Saver Ramps for Flat Spot Flat Tire Prevention and Vehicle Storage for Vehicles up to 10 Tons, Black, Set of 4

This is the second set bought. First used on an Aston Martin with low profile and wider tires. Worked well. Challenge is getting the vehicle on them as the ramp and lip take a bit of power to overcome particularly with a standard transmission on a high performance car and if the garage floor has a bit of upslope. Once on the ramp they cradle the tires nicely ensuring no flat spots. Rubber feet on the bottom make sure they don't slip when trying to load on to them. I have an unfinished concrete floor so nothing moved. On a shiny floor or one with less friction need to ensure they don't move or you could overrun one of them and if your car is low profile will hit the bottom of the vehicle.

I never though it would work based on some reviews. However I gave it a shot for my Supra and it worked perfectly at least for the rear tires. I only had issues with front wheels because my car is lowered.

Disappointed — Poor Quality, Not Suitable for Porsche 911 (2024) I purchased this item expecting it to be compatible with my 2024 Porsche 911, but unfortunately, it fell far short of expectations. The build quality is extremely poor — flimsy materials, weak grip, and a generally cheap feel that does not match the premium standard of the car. It doesn’t fit securely, feels unstable, and frankly, I couldn’t trust it during use. This product might work for a generic setup, but it’s absolutely not suitable for a vehicle like the 911. Waste of money. Strongly recommend avoiding it if you’re looking for something durable or reliable.

I bought these after having to replace tires on my car because of flat spots. As others have stated they do tend to slide on concrete. However with a little finesse zi got the car up on them. I have a mustang with only about 4" of front end clearance and they worked fine. Also plenty of width for my 285.75.18 tires

Used these ramps on my Teep Trackhawk for 6 months during winter storage in 2021. No issues whatsoever. I did hear a few reviewers say that they were difficult to drive onto so decided to just jack up the truck and place each one under tires. Not a big deal. Extra 30 minutes. The first year of using them was on regular street tires and worked great. This year will be trying them on my Mickey Thompson ET Street SS softer drag radials. These tires are considerably softer than the street tires but hope to have the same positive result. Will report back in spring 2023.
