What is a Space Saver Spare Wheel?
What is a Space Saver Space Spare Wheel : UK Driver’s Guide
When someone mentions “spare wheel,” you might think of a full-size backup. But a space saver spare wheel is different — smaller, lighter, and designed for emergencies. In this blog we’ll cover what’s the difference between a spare wheel and a space saver wheel, the main disadvantages, whether it’s an MOT failure, driving on motorways, and whether all space saver wheels fit all cars.
Let’s break it down, so you know exactly what you’re buying — and why it’s a smart investment. And if after reading you’re ready to shop, head to Space Saver Wheels Store.
What’s the difference between a spare wheel and a space saver wheel?
| Feature | Standard Spare Wheel | Space Saver Spare Wheel |
|---|---|---|
| Size / Width | Matches your existing wheels | Narrower and more compact |
| Weight | Heavier | Lighter |
| Handling / Grip | Same as normal | Reduced grip, more compromise |
| Intended use | Temporary or full replacement | Emergency / temporary only |
| Cost & storage | Requires more space | Compact, |
In short: a full spare is almost a clone of your existing tyre, while a space saver accepts trade-offs for the sake of compactness and lightness.
What is the main disadvantage of a space saver spare tyre?
The biggest drawback is reduced performance. In particular:
- Lower grip and stability
- Limited speed and range
- Increased wear if used too long
In effect, the main disadvantage is that it is not a permanent solution — it’s a stop-gap until you can replace or repair your full tyre.
Is a space saver wheel an MOT failure?
Generally, no — having a space saver wheel by itself is not an MOT failure. However:
- The tyre itself must be legal (correct tread depth, no illegal damage)
- It must be fitted properly and safely
- If the wheel is incompatible or causes safety issues (e.g. rubbing, instability), that could lead to failure
So long as it meets legal requirements and is fit for purpose, you can pass an MOT even with a space saver installed temporarily.
Can I drive on the motorway with a space saver?
Yes — in many cases — but cautiously. Key guidelines:
- Obey speed limits (often max 50–70 mph)
- Stay in left lanes and avoid overtaking where possible
- Avoid harsh acceleration, braking, or cornering
- Replace with a permanent tyre as soon as possible
Some drivers worry about motorway use, but with proper caution, it’s permissible — it’s better than being stranded.
Do all space saver wheels fit all cars?
No — just like we covered in Blog 2, space saver wheels do not universally fit all vehicles. Compatibility factors matter:
- Bolt pattern / PCD
- Centre bore
- Offset / ET
- Load rating
- Diameter and width
Only a correctly matched space saver will perform safely and legally. Use fitment guides, manufacturer data, and supplier filters to ensure you get the right one.
Summary & Next Steps
A space saver spare wheel is a compact, lightweight emergency wheel designed to get you home—not a long-term solution. It has limitations in grip, speed, and fit. It won’t inherently fail your MOT, and with care, you can use it on motorways. But always prioritize fitment — not all space savers fit all cars.
