Adco Tire Cover diameter

This spare tire cover is designed to fit 21-1/2" diameter tires. For best results when covering larger tires, lay the cover in the sun for a few minutes before installation. This allows the material to expand so that it will more easily fit over the tire.


Fits the following tire sizes:

  • 4.50 x 12
  • 5.30 x 12
  • 4.00 x 12
  • 4.80 x 12
  • 6.00 x 9
  • 6.90 x 9

Accelerated rubber breakdown, which is commonly seen on tires as cracking and dry rot, will affect your spare tire even though it remains stationary on the back of your vehicle or trailer until you need it. The rubber of most tires contains protective waxes that are released to the surface when you drive on it. Because you're not using your spare, it's more vulnerable to damage caused by exposure to UV rays and ozone. In short, your spare tire will wear out even if its rubber has never met the pavement. A spare tire cover is one way you can combat this form of wear.

Video Transcript for Adco Spare Tire Cover Review

Today we're going to be taking a look at the ADCO spare tire cover. They're available in white, black, diamond plate, camouflage, and US flag. You can find them in a wide variety of sizes to fit your spare tire. We've got one on our fifth wheel trailer here today, but you can also find one to fit your RV, camper, or SUV. It's made with a durable construction that's going to be resistant to the elements and UV rays. It's going to help protect your spare tire from dry rot while keeping it clean. The cover is cold cracked treated so it's perfect for winter use.

The drain here at the bottom prevents water buildup inside. The rear seam is elastic to ensure a snug fit. It's very easy to install. Be sure that the drain is at the bottom. We'll start at the top, then just work our way down along the side.

Once we get it entirely on then we can straighten it. That's going to complete our look at the ADCO spare tire covers.

Great cover; just what I needed! Lightweight and affordable...fits just right! The Customer Service Team and I exchanged several emails before I ordered 3 items, and I am very happy with not only the products, but also the support, thanks again guys! If I had one thing to say that sure does break my heart, and that is simply this... I just wish a company that started in 1955 could make these ANYWHERE BUT CHINA!!!

Review from a similar Spare Tire Cover in Spare Tire Covers


Cover was of firm construction and fit slightly loos BUT next size down would have been to tight. My trailer tires are load range E so the cost benefit will be very positive fir me trusting that it will last longer than the one it replaced which was on the trailer for four years and was black, overall it is striking and had been installed for two days .. so time will tell

Review from a similar Spare Tire Cover in Spare Tire Covers


I've made a few orders with eTrailer.com and have received all of the products very quickly. The spare tire cover arrived the same week I ordered it, without any special shipping options, and it is a very good product. It fits snuggly on the trailer's spare tire so it won't blow off in the wind during transport. The vinyl is heavy so I expect it to last a good while. The spare is mounted on the front of the utility trailer so it will receive a good amount of wind.

Great. No problems

Review from a similar Spare Tire Cover in Spare Tire Covers


The problem: How to transport kayaks with smaller vehicle as weight of cross & kayak racks plus kayaks was above vehicle roof weight limits. So I shopped for a "kayak" trailer. The people at etrailer made the ordering process easy and successful to complete this project. Great trailer, impressed with the size & strength of frame, and assembly went together as instructed. Installed bunk boards and mounted Thule DockGrip for Kayaks. This for me is an easier and safer way to transport kayaks. Thank you etrailer...

Review from a similar Spare Tire Cover in Spare Tire Covers


I was concerned about the thickness of this cover since the box was pretty small. But once I opened the box and opened up the cover it was what I wanted. A thicker vinyl of better quality than I have had in the past from elsewhere. Excellent snug fit on my 27" diameter spare trailer wheel/tire considering it is already a little cold here in the Catskill Mts. keeping the cover from being as flexible and stretchable. Great customer service.

Review from a similar Spare Tire Cover in Spare Tire Covers


I was a tad worried from other reviews but upon receiving the cover I have NO worries. The fit is tight, the seams are good, per etrailers video I put saran wrap around the spare then installed the cover. Went on great NO fuzzy residue that some experienced. This cover will work great for our trailer.

Review from a similar Spare Tire Cover in Spare Tire Covers


I am disappointed in the tire cover which I had put over my spare on my utility trailer about 1 year ago. Just had to buy and put white duct tape over the top edge of the cover because it had developed several cracks in the vinyl. The main reason I am trying to save this cover is because I also had purchased a large US Navy decal which I had put on the face of the wheel cover and I do not want to have to try and find another Navy decal if I replace the cover.

Still disappointed- Continued deterioration

Review from a similar Spare Tire Cover in Spare Tire Covers


Product arrived in great time. It fits my tire and wheel snuggly so I won't worry about losing it while going down the road. It was soft and pliable, yet durable. The seams are well stitched and I plan on this tire cover lasting a long time. It will be covering the spare tire on my trailer, and the white color should help reflect the sunlight, keeping the tire cool and prolonging the life of the tire. After just receiving it and installing it, I am pleased with my purchase. Time will tell as to how it actually stands up to the elements, but I'm not expecting any problems. I will be a future etrailer.com consumer. :)


Comments
After a year in the weather, the tire cover has been doing its job and protecting my tire. No problems going down the road with its snug fit. Its still like new. Im very happy with this purchase!

Review from a similar Spare Tire Cover in Spare Tire Covers


Product was delivered on time and fits as it should. I bought this to cover my spare tire that is mounted on the front of my boat trailer. It does feel a little thin, so I will be curious how it holds up over time.


Comments
i trailer my boat throughout the summer. overall the cover has held up but is starting to tear along the bottom where rocks hit it more frequently, however i didnt expect it to last years though.

The Tow Mounts are really heavy-duty! Awesome! No problem mounting and the secure my LandCruiser like no body’s business. The Spare tire cover was fantastic too fits great. Protects the tire from UV and weather. Adds a class look. Pictures are after driving on a dirt road, do everything is a bit dusty.

We like the material, and its a snug fit on our spare RV tire so no worries about it coming off. The pattern is what we expected and it goes well with our trailer.

After carefully measuring my 205/75R14 trailer spare I purchased the size L (25.5”) Adco cover in spite of the chart that said I needed a size J (27”). Glad I did as it fits perfectly. Looks great.

This cover is functional but not over the top in quality. After a year it has signs of wear but will probably last another year
