Do I Really Need a Spare Tire Cover?

If your vehicle has an exposed spare tire, you’ve probably wondered whether a cover is necessary or just “optional.” Many drivers assume the spare isn’t important because they rarely use it — but that’s exactly why it needs protection.


A spare tire is your emergency backup. It’s the tire you rely on when everything else goes wrong. Keeping it uncovered exposes it to harsh sun, weather, and long-term damage that can make it unsafe when you finally need it.


Here’s the full breakdown of whether you really need a spare tire cover — and what happens if you skip it.


What Happens When a Spare Tire Is Left Uncovered?

An uncovered spare tire is exposed 24/7 to:

  • UV rays

  • Rain and moisture

  • Snow and freezing temperatures

  • Road salt and chemicals

  • Dust, sand, and road debris


Over months and years, this causes:

  • Dry rot

  • Cracking

  • Fading and discoloration

  • Tire hardening

  • Weak sidewalls

  • Reduced air retention


Even if the spare is brand new, exposure will silently damage it long before you ever use it.


UV Damage Is the #1 Reason Tires Fail Early

Rubber breaks down quickly under direct sunlight. The sun pulls essential oils out of the rubber, causing it to:

  • Dry

  • Crack

  • Fade

  • Lose elasticity

  • Become structurally weak


A dry-rotted spare tire is unsafe — even if it has never touched the road.


A high-quality cover blocks UV rays and slows the aging process dramatically.


Weather Exposure Shortens Tire Lifespan

Rain, snow, and moisture accelerate rubber breakdown. Road salt and chemicals cause corrosion on the wheel. Hot-cold temperature cycling stresses the tire.

All of this happens fast when a spare is exposed.


A cover shields the tire from these conditions and keeps the rubber healthier for much longer.


A Spare Tire Cover Improves Safety

If your spare tire fails when you need it, you’re stuck. Driving on a dry-rotted or cracked spare can lead to:

  • Blowouts

  • Rapid air loss

  • Tread separation

  • Sidewall failure


A simple tire cover prevents most of the aging that makes spare tires unsafe.


It Also Makes Your Vehicle Look Better

A bare spare tire can look:

  • Dirty

  • Faded

  • Mismatched

  • Weathered


A cover instantly cleans up the rear appearance of your vehicle. For popular models like the Jeep Wrangler, Ford Bronco, Toyota RAV4, CR-V, and FJ Cruiser, a good cover becomes a design feature — not an afterthought.


You can choose:

  • Blank black vinyl

  • Wildlife designs

  • Adventure themes

  • Patriotic graphics

  • Custom art


It’s protection and personalization in one.


It Helps Prevent Theft and Tampering

A spare tire is easy to steal when fully exposed. A cover:

  • Conceals the spare

  • Makes access slower

  • Hides mounting bolts

  • Protects backup camera wiring (Bronco, Wrangler)


Thieves go for easy targets — a covered spare is far less appealing.


Cheap vs High-Quality Spare Tire Covers: What’s the Difference?

Cheap imported covers may last only a few months. They often:

  • Fade quickly

  • Crack in heat or cold

  • Fit loosely

  • Stretch out

  • Blow off while driving


A USA-made SpareCover® lasts years longer because it uses:

  • Marine-grade vinyl

  • Reinforced stitching

  • Outdoor-rated UV inks

  • Strong retention

  • Precision sizing


The difference in durability is huge.


So… Do You Actually Need a Spare Tire Cover?

Yes — if your spare tire is exposed, a cover is absolutely worth it.

A spare tire cover:

  • Extends tire life

  • Prevents dry rot

  • Protects from sun and weather

  • Stops fading

  • Keeps the tire clean

  • Reduces theft risk

  • Improves vehicle appearance


It’s a small accessory that prevents major issues down the road.


Final Thoughts: Protect Your Spare Before You Need It

A spare tire is only useful if it’s in good condition when you need it.


Leaving it uncovered exposes it to years of damage that weakens the rubber long before you ever get a flat.


A high-quality, USA-made SpareCover® offers the best long-term protection and keeps your vehicle looking sharp.


Protect your spare tire now and enjoy peace of mind knowing it will be ready when you truly need it.
