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.

This is a good product at a good price. It fits nice and snug and there's no chance it will come off accidentally. This is thicker material and better construction than the last cover I had, which was a different make entirely. This looks like it will weather well and last a long time. 867877

Review from a similar Spare Tire Cover in RV Covers


The spare tire cover fit perfect on the pop up camper. My husband was very pleased with the fit, and the water drain off on the bottom of the tire cover. The cover gave the camper a much better look, and the quality seems very good. The order was simple, and shipping time was great. We are pleased with everything, Thanks. 504875

  • Recommended Tire Cover for 5.30-12 Size Tire with Bar From Carrier Extending Through Wheel
    The Adco Spare Tire Cover # 290-1740 that you referenced is a great fit for 5.30-12 size tires but I'm worried that it's too good of a fit, meaning there won't be a lot of slack available for the extra 1-1/2 inch width that the bracket from your carrier creates. Because of this your best option is going to be a slightly larger cover like the Adco # 290-1739, which is technically designed for tires that are up to 24 inches in diameter (your 5.30-12 tires has a diameter of around 21.9...

  • Recommended Spare Tire Cover for 205/65-10 Tire
    For your 205/65-10 tire that has an outer diameter of 20.5 inches, I recommend the Adco Spare Tire Cover - 21-1/2" Diameter # 290-1740. This will give you a slightly larger diameter to assist with the tire being wider. This is the best fit we have available for your tire and it has an elastic enclosure for a snug fit.

  • Recommended Cover for 21-1/2 Inch Diameter Spare Tire
    If your tire has a 21-1/2 inch diameter I recommend the Adco Spare Tire Cover - Black # 290-1740. This particular cover is a perfect fit for this size tire and it features a double vinyl construction that will do a great job of protecting it while it's waiting to be used (but hopefully you won't ever have to!). Its elastic opening with a hollow-beat welt cord ensure a snug fit and an easy install. This cover is also available in White # 290-1760 and Diamond Plate # 290-9760. I have...

  • Recommended Spare Tire and Storage Covers for ST205/65-10 Trailer Tire
    A trailer tire of size ST205/65-10 has an overall diameter of 20-1/2-inches so you'll want a spare tire cover that will fit a 21-inch or larger size. The linked page displays all spare tire covers in an appropriate size, including Adco black cover # 290-1740, camo cover # 290-8760 and Camco white cover # CAM45349. Covers protect your valuable tires from premature aging from UV-rays and exposure to the elements. It is also a good idea to protect your mounted tires during storage periods...

  • Spare Tire Cover for 145/R12 Trailer Tire in Black
    A ST145/R12 trailer tire like the Kenda Karrier # AM10130 measures 21.3" in diameter and 5.7" wide, and we do have spare tire covers which come in black that fit this size tire. What you need is one of the following spare tire covers: - Adco Spare Tire Cover # 290-1740 - Camco Vinyl Spare Tire Cover # CAM45261 I have added links to video reviews for you to check out as well.

  • Thermoplastic Vs. Vinyl Spare Tire Covers
    The Adco Spare Tire Cover part # 290-8760 is indeed the correct size spare tire cover for your 5.30-12 tires. As you mentioned, it is constructed of a durable thermoplastic polymer. The reason for the thermoplastic as opposed to vinyl is because it is easier to print on than vinyl. It feels just like vinyl but is a bit smoother to the touch. I wouldn't really say one is glossier than the other. There shouldn't be an excessive noise with the cover. If you would like a black vinyl cover...

  • Spare Tire Cover for 20.4 Diameter x 8.4 Wide Kenda Tire
    Yes we do have a cover that will fit the 20.4" diameter x 8.4" wide Kenda Loadstar # AM3H454 you just got. The Adco Spare Tire Cover # 290-1740 is designed to fit 21-1/2" diameter tires but it has an elastic cord that will allow it to still fit over your tire and work as intended.

  • Recommended Spare Tire Cover to Fit a 5.30-12 Trailer Tire
    I recommend the Adco 21-1/2 inch Tire Cover, part # 290-1760. Your 5.30-12 sized tire is about 21-1/2 to 22 inches in diameter so this is the correct size. The cover is also availabe in Black, part # 290-1740, Camouflage, part # 290-8760, and Diamond Plate, part # 290-9760.
