can you back up into these? i back back my car into my garage.

I can't see why not. The ramps don't know which way the vehicle is oriented as the tires roll up onto the ramps. The trick with a garage is having the vehicle end up where you want it in the garage, AFTER it's situated on the ramps. I'm going to write the description below as if you're driving into the garage nose first - you'll want to reverse front and rear as necessary below if you intend to back in.Note that you do NOT place all four ramps in their final location before you begin to drive into the garage, as this would mean the front tires would have to go up, over and off the rear ramps before they reach and begin to go up on the front ramps. What you need to do with your new ramps is to first measure the horizontal distance between the lip (lowest edge) of the ramps, and the center of the concave portion of the ramps (where the tire will end up). Let's say for discussion purposes that this distance is 20". You drive the vehicle into the garage with the desired left-right orientation, to a point approximately 20" BEHIND where you want it to end up when it's situated on the ramps, and initially stop there. Then you place all four ramps on the floor, centering them (left-to-right) on each of the tires, pushing the lower lip of each ramp just touching/pinched underneath) the front edge of each tire (at the front of the patch where the tire contacts the floor). This means as soon as the car begins to move forward, all four tires will begin going up onto their respective ramps at the same time. Though the manufacturer says it doesn't matter, I recommend having both the floor underneath the ramps and the top and bottom surface of the ramps themselves be as clean and free of dust, dirt, liquid or anything else that would cause it to slip relative to the tire as the latter goes up on it. You then slowly drive the car forward, and it will roll up on the ramps, and at some point all four tires will drop into the concave depression of the ramps at about the same time. Do this VERY slowly, as it will be a rather substantial jolt as the tires simultaneously drop into the depression on the ramps (depending on your suspension, it will feel like you drove off a curb). Get out of the vehicle, and inspect how each tire is seated in each ramp, left/right and front/rear, to make sure nothing moved while you were driving the vehicle up on them.Also note that when you drive (forward or backward) OFF the ramps, you have to follow the reverse process to that outlined above. As soon as you are off the ramps (immediately after the front and rear tires contact the garage floor), get out and move at least the two ramps that are still under the vehicle, out of the way. Otherwise you'll end up driving over them in the wrong direction, which will not be enjoyable for either the ramps, the vehicle, you, and/or your underwear.The following section is intended for engineers and others like myself who understand that anal-retentive and obsessive-compulsive are both necessarily spelled with a hyphen).if the aspect ratio (the ratio of a tire’s section height to its section width when the tire is: inflated to maximum air pressure) of the front and rear tires is not the same, the circumference of the front and rear tires may be slightly different. On rear-wheel drive vehicles, for example, It can mean that (in this example) the circumference of the rear tires is slightly larger than that of the front tires. If you initially position the front lip of the ramps the same way under the front and rear tires as outlined above, you may find that the front tires end up not exactly centered on the front ramps, You'll be able to feel this more than see it, by sliding something like a paper envelope underneath each tire from each (front/rear) direction, after each tire is seated in the ramp depression). In my case this resulted with the front tires being slightly less than an inch behind the physical center of the ramp depression, while the rear tires were exactly centered in the ramp depressions. If this turns out to the case for you, and you're concerned about it, initially place the front tire ramps, very slightly (probably less than an inch) forward of where you put them for the rear tires (this means the rear tires will contact and begin climbing their ramps VERY slightly before the front tires contact and begin climbing theirs). If you are using the ramps for a vehicle like a hot rod, where the rear tires are often substantially taller and wider than the front tires, this distance will be somewhat larger and may be significant. If you're mathematically inclined, you can calculate this distance/difference, but if you're not, you'll probably find that trial-and-error is easier. Unless your front and rear tires are substantially different in circumference, you probably won't find the difference to be significant enough to be concerned with. In any event, don't let it affect your decision to get these ramps, it's really no t that big a deal - you'll see how to tune the correct position for the ramps the first or second time you use them.Good Luck !!

If the tires drop into place slightly off angle will this ruin the tire or will the material form to hug the tires??

The product does not form to the tire. Rather tire lies within the curvature and keeps the tire from getting flat spots. Tires placed straight in groves will hold their forms.

Are 16" (rr-fs-16-sc) available in red color? if so, what designation do i use to order them?

We do not have the RR-FS-16-SC available in the color red anymore. We have stopped spraying all products in the color red as of January of this year.

What size needed on tire size 255/35/18

The wheel width determines the size needed. It’s a little difficult to drive up 4 narrow ramps So I suggest the 16” ramp. You don’t have to be precise . You will have some room on either side of the tire to cradle the tire.

Seem great so far, figured out the trick

So far so good. I figured out the trick!I have a 2025 911 Turbo S. Rims are 20 front 21 back. If you have staggered tires you can't just jam them up to the back of the tire. I have an old metal level. Its about 1.25 inches wide. For the back tires I used that as a spacer to line up the back ones, then slid it out. All 4 tires ended up in the groove perfectly on the first try

If you invest in quality tires, invest in their longevity.

Perfect for long term storage. I put my car up on these if I won't be driving for 30 days or more. If you are deciding between two sizes, get the larger of the two. The supercar one really is for ultra-wide tires... these are great for a 2006 BMW M3. The next size down (14") is good for most vehicles... I have them on a 2007 BMW X5 SUV with fairly large tires. Race Ramps RR-FS Flatstopper (Pack of 4) The 10" ones really shouldn't be used for full-size cars... its for ATVs etc. For oil changes and other self-maintenance, I use these ramps (didn't but them on Amazon, but they are great).

Light weight, easy to use, but a little costly.

Easy to roll your car onto it despite what others say. Only concern is getting the tires to drop exactly to fit the curvature of the ramp. If you are off a couple of degrees I am worried it will damage tires. First winter for me storing 2015 Z06. Will update if it is a negative result.

These work well for the designed purpose. They are not the easiest to use though. Getting all 4 wheels fully on them at the same time is tricky and takes some time. It may just be me but I have to try a few times to get all four tires on them and so far I have yet to really get it perfect. I always have one tire that is a little too far forward or too far back. But they do keep the tires off the cold concrete and prevent flat spots!

WARNING! Needed to replace brand new tires after first and only use!

I have a car in Arizona that I use when we're snowbirding, so from about April to December that car remains stored as we're back up north. Wanting to prevent flat spots I ordered the highly rated Flatstoppers by Race Ramps, fully inflated my tires, and rolled up onto the ramps confident that they would do as they claimed. I followed the fairly simple and intuitive procedures and departed until the next winter. When I returned months later, I uncovered the car, disconnected the trickle charger, and gently rolled the car off the ramps. The tire pressures had dropped from 33 PSI to 26 PSI during storage so I topped them up and went off on a short drive. I immediately felt a wobble! The Race Ramps site suggests that some temporary flattening may occur but that should be able to be driven out after about 25 miles. Well, it DID improve, but even after about 50 miles when driving between 50 and 70 MPH the car felt like it wanted to jump off the road. I should mention as well that these were brand new Michelin Defenders with only a few hundred miles on them. I went to Costco (where I bought them) for an inspection and they rebalanced them but they confirmed that all 4 tires had flat spots. Not a warranty issue. So these brand new tires were trashed thanks to Race Ramps requiring a replacement. Next year I will be putting the car up on jack stands. I have emailed and called Race Ramps and there has been no reply as yet. I will update this review if they accept responsibility. I DO NOT RECOMMEND RACE RAMPS FLAT STOPPERS!

Prevent Flat Spotting!

These ramps are worth their weight in gold. Very easy to pull up on and no issues with them sliding or scooting away. They have the curvature to prevent your tires from getting out of round and creating flat spots that ultimately will make the sheets have a thumping sound that may or may not roll out over time. Definitely a must have if you plan to have car parked for a significant amount of time.

perfect product. I stored my car from sept 2018 until May 2019 on cold concrete floors. it gets to -30 C at where I live and I was glad to see my car did not develop any flat spots. Would recommend for any long term storage!!!

Helps to prevent flat spots on tires during long storage. Also raises the height of the car on low clearance sports cars to allow using a jack to lift the car to perform service. https://www.amazon.ca/dp/B01MPXRQGC/ref=cm_cr_ryp_prd_ttl_sol_0
