Drawstring vs Elastic Band Tire Covers: Which Attachment is Better?
May
If you have spent any time shopping for a spare tire cover, you have probably noticed two very different attachment styles on the back of the listings. Some covers have a thick elastic band that grips behind the tread. Others have a drawstring cord that you tighten manually with a clamp at the back of the spare. They look almost identical from the front, and most shoppers ask the same reasonable question: which one is actually better?
The honest answer is that neither attachment is universally better. They solve the same problem — keeping the cover snug against the tire through wind, weather, and highway driving — in two slightly different ways. Each has trade-offs you only really notice after a year or two of use.
The reason you do not get to choose freely between them is that the attachment is built into the material itself at production. Polyester, the lightweight fabric in the entry tier, uses a drawstring cord. Every other material we make — PVC, PU Leather, and Marine Grade Vinyl — uses an elastic band.
Here is how each system works in practice, and the situations where one ends up clearly better than the other.
Polyester covers ($69) use a drawstring cord that tightens at the back of the spare and can be re-tightened any time. Every other material — PVC, PU Leather, and Marine Grade Vinyl — uses a sewn-in elastic band that grips behind the tread and needs no adjustment. Both systems stay put at highway speeds in normal driving.
Drawstring cord attachment (Polyester only)
The drawstring system runs a cord sewn around the inside circumference of the cover. The cover slides over the front of the tire, the cord is pulled tight at the back, and a cord-lock clamp holds the tension. Installation takes about a minute the first time and seconds after that. Polyester is the only material in our range that uses it.
What it does well
- Adjustable to any diameter. Fine-tune to non-standard tire sizes, oversized tires, or anything outside the typical OEM spec.
- Re-tightenable for years. If the cover loosens over time, after a hand wash, or after long shipping, you just retighten the cord and clamp.
- Easy to swap. The cord loosens fully, so seasonal design changes take seconds.
The trade-offs
- Slightly slower install on day one — you tighten a cord instead of just stretching a band over the tire.
- The cord-lock clamp itself can wear after several years of UV exposure, though it remains replaceable.
- It only comes on Polyester. If you want the drawstring, you are also choosing our lightest-duty material — rated to about 2 years outdoors. There is no drawstring option on the longer-lasting materials.
Elastic band attachment (PVC, PU Leather, Marine Grade Vinyl)
The elastic system runs a wide, heavy-duty elastic band sewn around the inside edge of the cover. The cover stretches over the front of the tire and the band grips behind the tread automatically. Once it is on, there is nothing to adjust. This is the attachment on every material above the entry tier, including the 5-year Marine Grade Vinyl and the Marine Grade Vinyl + Anti-Theft Kit.
What it does well
- Fastest install. Stretch it over the tire and walk away — no tightening required.
- Flush, factory look. The elastic pulls the cover tight against the spare without any visible cord at the back.
- Self-tensioning. Vibration and weather do not loosen it the way a drawstring can.
- Comes on the durable materials. Every cover rated beyond 2 years outdoors uses it, up through the 5-year Marine Grade Vinyl.
The trade-offs
- Less adjustable. Works best on stock tire sizes; non-standard tires can be too tight or too loose.
- Elastic degrades over time. After 4–5 years of UV exposure, the band stretches out and the grip loosens.
- Not separately replaceable — once the elastic gives up, the cover does too.
How to pick between them
You do not really pick the attachment on its own — you pick the material, and the attachment comes with it. The pairing is:
- Polyester ($69) → drawstring cord.
- PVC ($99), PU Leather ($129), Marine Grade Vinyl ($169), Marine Grade Vinyl + Anti-Theft Kit ($199) → elastic band.
Because the split is lopsided, the practical decision is simpler than it looks. If you specifically want the adjustability of a drawstring, you are choosing Polyester and its roughly 2-year outdoor life. Everyone else picks the material that suits their climate and use, and takes the elastic band that comes with it. In day-to-day use, most owners do not notice a meaningful difference once the cover is installed — both systems stay put through normal driving, weather, and highway speeds.
Where the Anti-Theft Kit fits in
The Marine Grade Vinyl + Anti-Theft Kit ($199) is sometimes mistaken for a third attachment system. It is not. It fits with the same elastic band as the standard Marine Grade Vinyl. The lock is a separate layer on top: two reinforced grommets are set into the cover, a steel cable threads through them, and a padlock and key close the cable. With the cable locked, the rear opening cannot be spread wide enough to pull the cover back off over the tire.
Frequently asked questions
Which attachment lasts longer in the real world?
The attachment is rarely what fails first — the material is. Polyester’s cord-lock clamp is replaceable, but the fabric itself is rated to about 2 years outdoors. The elastic band is not separately replaceable and loses some tension after 4–5 years of UV exposure, but it is fitted to the materials rated to 3–5 years. In practice, the cover reaches the end of its material life at roughly the same time as its attachment.
Will an elastic-band cover stay on at 70 mph?
Yes. Elastic bands grip behind the tread and are tested at highway speeds. Under normal driving conditions, the cover does not shift.
Does the Anti-Theft Kit use a drawstring lock?
No. The Marine Grade Vinyl + Anti-Theft Kit fits with the same elastic band as the standard Marine Grade Vinyl. The lock is a steel cable that threads through two reinforced grommets in the cover and closes with a padlock and key, so the cover cannot be pulled back off over the tire.
My Polyester drawstring loosened. What do I do?
Tighten the cord-lock clamp at the back of the spare. Pull the cord through the clamp until the cover is snug against the tire, then click the clamp shut. The whole adjustment takes about ten seconds.
Does one attachment hold a backup-camera hole position better?
Both do, if the cover is installed correctly. The free centered backup-camera hole is cut to spec on every cover regardless of attachment. As long as you align the cover squarely on installation, the hole stays where it belongs.
