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 tire cover protects your 21-1/2" diameter spare tire from dirt, road salt, and harsh UV rays. Vinyl cover slips over tire quickly and easily, and the elastic opening ensures a snug fit. Vented bottom stops water buildup.


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...


I was very please with the spare tire carrier and cover. The quality is great and it shipped very quickly.


I completely blasted and restored my 4x8 folding trailer . I bought all the new items from etrailer and am very happy with all .


Product was exactly as advertised and fit my spare tire perfectly.


Great wheel covering product. Trailer sits on a lot in N. Texas. Always exposed to the elements. After one year still looks new. Highly recommend these covers.

Most Excellent! Very happy w tire covers.

Tire and wheel covers are excellent! Thank you ?


It's exactly what I was looking for! I'll be doing more shopping, Thank you.



still holding up well thanks again
FRED B - 02/09/2019


Received quickly and product works well. Good quality and fits perfectly.


etrailer did a great job advising what size cover to get for the tire size on my trailer. It fits perfectly. Well made too!


The service was quick, the tire cover fits perfectly. I'm pleased with etrailer!


Excellent my brothers very satisfied with the quality


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.


First time shopping at etrailer. Just received my ordered item. Very easy. You have a nice inventory of products. I will be back. Thank you.


Awesome has held up very well.


Received tire cover in short period of time and was exactly what was shown in description.


It covers tire.
More pliable than some
other should last longer.
Easy to get on but fits tight when on.


very nice i like it

Great - keeps rain and snow off.

  • 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.

  • Spare Tire Cover Recommendation for 5.30-12
    For a black spare tire cover for your trailer tire size of 5.30-12 the Adco Spare Tire Cover part # 290-1740 would be a really great option that is the correct size. The Adco covers like this have a great 3 year warranty, are made from a high quality vinyl, and are vented on the bottom to prevent water from building up.

  • 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 inches)....

  • 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...

  • 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

  • Spare Tire Cover for 145/R12 Trailer Tire in Black

  • 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 and Carrier For CE Smith Multi Sport Boat and Kayak Trailer
    For the CE Smith Multi Sport Plus Boat and Kayak Trailer # CE48870 I recommend the Loadstar 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30670. The galvanized wheel will match what comes on the trailer. The spare tire carrier will depend on how you would prefer to mount the spare. A CE Smith Spare Tire Carrier # CE22007Z-11050-2 will allow you to mount the tire horizontally on top of the trailer. This would work best near the a-frame of the trailer to support the tire. The...
