Students who share a car with housemates, or who drive a small used vehicle to a placement, often treat tyres as something to think about only when a warning light appears. Tyres are the one part of a car that touches the road at all times, so their condition affects braking, steering, and fuel use every single day. A short monthly check takes only a few minutes and can catch problems while they are still cheap to fix.

Why tyres deserve regular attention

Tyre pressure changes with temperature, and a drop in cold weather can leave a tyre noticeably soft without any obvious sign. Under-inflated tyres wear unevenly, heat up more, and make the car feel sluggish. Over-inflated tyres can reduce grip on wet roads and cause a harsher ride. The correct pressure is usually printed on a sticker inside the driver’s door frame or in the vehicle handbook, and it is that figure you should follow rather than the maximum shown on the tyre wall.

Tread depth matters for wet weather. Shallow tread channels cannot clear water quickly, which increases the risk of aquaplaning on a motorway or a flooded road. Many areas have a legal minimum tread depth, and it is sensible to replace tyres well before that limit if you drive often in rain or on rough surfaces.

A simple monthly routine

Set aside a few minutes at the start of each month, ideally when the tyres are cold, such as before a morning drive. A cold tyre gives a more accurate pressure reading because driving warms the air inside and raises the pressure. You will need a reliable pressure gauge, which can be bought cheaply, and a coin or a tread-depth tool to check the grooves.

• Check the pressure in all four tyres and the spare if the car has one
• Look for cuts, bulges, or nails lodged in the tread
• Run a coin into the main grooves to judge the tread depth
• Check that the valve caps are fitted and the valve stems look intact

Write the date and the readings in a small notebook kept in the glovebox or in a note on your phone. Patterns become clear over a few months, for example if one tyre always loses air faster than the others, which often points to a slow puncture or a leaking valve.

Common mistakes to avoid

One frequent error is adjusting pressure based on what a friend recommends for a completely different car. Another is ignoring a slow leak because the tyre still looks round. A tyre that needs air every week should be inspected by a tyre centre rather than topped up repeatedly. Students sometimes also rotate tyres in a way that does not match the manufacturer’s advice, which can make wear patterns worse. If you are not sure, ask a garage to show you the correct pattern.

Mixing tyre types on the same axle is another common issue. Different sizes, brands, or tread patterns can behave unpredictably, especially in an emergency stop. When you replace only two tyres, a professional can advise on whether it is safer to fit a matching pair on the same axle.

What to do when something looks wrong

If you find a deep cut in the sidewall, a bulge, or uneven wear across the whole tread, stop using that tyre and arrange an inspection. Sidewall damage is often not repairable, and a sudden failure at speed can be dangerous. A slow puncture in the tread may sometimes be repaired, but only if the hole is small and in the central area; a qualified tyre fitter should decide that rather than a roadside guess. Keep the spare tyre inflated too, because a flat spare is useless on the day you actually need it.

If the warning light for tyre pressure comes on while you are driving, pull over somewhere safe, check the pressures, and inflate any tyre that looks low. Keep a small tyre inflator or a portable compressor in the car if the vehicle allows it. Readers may also want to visit bajiroo.com.

Keeping the habit going

A tyre check becomes easy once it is linked to something you already do. Some students check pressures every time they fill the fuel tank, while others pair the check with a weekly car wash. Shared cars need a rota so that one person is not always doing the work, and a simple shared note can record who checked what. You can also visit Wheon News for more reading.

Good tyres are an inexpensive safety investment. A few minutes each month can prevent a dangerous skid, extend the life of a set, and save money on fuel. When in doubt, a professional inspection is always the safer choice.
