When it comes to looking after your car, tyres often come with a lot of old advice and persistent myths. While some of these tips might sound sensible, following them can actually lead to poor performance, faster wear, and even unsafe driving. Let’s clear things up by looking at some of the most common tyre myths you’re likely to hear.
Over-Inflating for Better MPG
You might have heard that adding a bit of extra air to your tyres can magically boost your fuel economy. The idea is that harder tyres roll more easily. There’s a tiny bit of truth here, but the reality is that over-inflating your tyres for gas mileage is a bad move. Tyres with too much air have less contact with the road. This significantly reduces your grip and makes braking worse. It also causes the middle of the tread to wear out much faster than the edges, meaning your tyres won’t last as long. Your ride will feel harsh and bumpy, and you’ll be at a higher risk of a blowout. Any small fuel savings you might see just aren’t worth the safety risks and extra cost of replacing tyres sooner. The argument to boost gas mileage this way simply doesn’t hold up against the downsides. Always inflate your tyres to the pressure your car’s manufacturer recommends. You can usually find this on a sticker inside the driver’s door jamb.
All-Season Tyres for All Conditions
The name “all-season” can be a bit misleading. While these tyres try to do a bit of everything, they don’t excel at any one thing. All-season tyres are a good compromise for drivers in places with mild winters and warm summers. They perform acceptably in dry and wet conditions and can handle light snow. However, they’re not a replacement for dedicated winter or summer tyres. In heavy snow or icy conditions, they don’t have the deep treads and special rubber compounds that winter tyres do for proper grip. Likewise, in hot weather, they can’t match the cornering stability and braking power of high-performance summer tyres. Picking the right tyres for your climate and how you drive is crucial for both safety and performance.
Patching Any Puncture
Getting a nail in your tyre is annoying, but the good news is that many punctures can be fixed. The myth, though, is that any puncture can be patched up. This is dangerously wrong. For a repair to be safe, the puncture must be in the main tread area of the tyre. Any damage to the sidewall or the shoulder (where the tread meets the sidewall) can’t be safely repaired, meaning you’ll need a full replacement. The tyre’s structure in these areas is vital for its strength, and a patch or plug simply can’t restore it. Also, the puncture itself shouldn’t be larger than about a quarter of an inch across. A professional car repair involves taking the tyre off the wheel to check the inside and using a combination patch-plug to seal the hole completely.
New Tyres Go on the Front
This is probably one of the most common and risky misunderstandings. When you’re only replacing two tyres, it might seem logical to put the new ones on the front, especially on a front-wheel-drive car where the front tyres handle steering and power. However, for safety, new tyres should always go on the rear axle. The reason is simple: vehicle stability. Your rear tyres are what stop the back of your car from sliding out, a dangerous situation called oversteer or “fishtailing.” New tyres have deeper tread and offer better grip, especially when it’s wet. By putting them on the back, you make sure the rear of the car stays stable and predictable, which reduces the risk of spinning out during a sudden turn or lane change on a slippery road. The front tyres might wear faster, but you’ll have far more control over your vehicle with fresh tread on the back.
Understanding the truth behind these common myths helps you make better choices for your car’s safety and how long it lasts. Proper tyre care isn’t just about saving money; it’s about making sure you and your passengers are safe on every trip.
