Tire Maintenance Guide
Regular, simple maintenance is the difference between a set of tires that lasts and one that fails early. This guide covers pressure, tread, rotation, balance, alignment and the inspection habits that keep tires safe.
Direct answer
Maintain your tires by checking pressures monthly when cold and setting them to the vehicle placard figure, measuring tread depth regularly, rotating tires at the interval your manufacturer recommends, keeping wheels balanced and alignment correct, and inspecting for damage. Well-maintained tires wear evenly, last longer and are safer.
Before you begin
You need very little to keep tires in good condition: an accurate pressure gauge, a tread depth gauge, and the figures and intervals from your owner’s manual. Start by writing down your vehicle’s recommended pressures, the rotation interval and any load-specific pressure settings for heavier loads or towing.
Step-by-step guide
Pressure: the foundation of tire care
Nothing you do for your tires matters more than getting the pressure right. An underinflated tire flexes more, runs hotter, wears faster and can fail; an overinflated one wears in the centre and grips less evenly. Set pressures to the figure on your vehicle's placard when the tires are cold, and adjust for heavy loads or towing if your manual specifies different figures.
Check monthly, and more often when temperatures swing. Air contracts as it cools, so a tire that was correct in summer can be low on the first cold morning of autumn. If one tire always needs topping up, treat it as a slow leak and have it investigated.
Tread: measure it, do not eyeball it
Tread depth determines how well the tire clears water. Use a tread depth gauge and measure in several places across the width, because a tire can be legal in the middle and bald on one edge. Uneven depth across a tire is a clue: wear on both edges suggests underinflation, wear in the centre suggests overinflation, and wear on one edge alone often points to alignment.
Replace tires before tread reaches the legal minimum. Wet grip falls away noticeably below four thirty-seconds of an inch, even though the legal limit is two.
Rotation: spread the wear
Front and rear tires work differently — driven, steering and braking loads vary by position — so they wear at different rates. Rotating them on the schedule your manufacturer recommends spreads that wear and lets the whole set last longer. Rotation is also a good moment to inspect each tire off the vehicle and to check the pressures.
Balance and alignment
Two services keep wear even and driving smooth. Wheel balancing corrects uneven weight distribution in the wheel-and-tire assembly, which otherwise causes vibration at speed. Wheel alignment sets the wheels' angles to the manufacturer's specification; if alignment is out, tires scrub and wear quickly on one edge. Have alignment checked after kerb strikes, pothole impacts or any collision, and whenever the old tires wore unevenly.
Safety first: Vibration or a pull to one side is a signal, not an inconvenience. Have the tires, wheels and alignment checked before it damages a new set.
Inspection: catch problems early
Every pressure check is also an inspection. Run your hands over the tread and sidewalls (carefully, in case of sharp objects), look for bulges, cuts, cracks and anything embedded in the tread. Check the valve stems for cracks or leaks. Note anything unusual — a change in noise, a vibration, or a tire that looks different from the others — and have it checked.
Simple habits, big returns
Maintaining tires is not complicated, and the rewards are immediate: even wear, better fuel economy, shorter stopping distances and fewer surprises. An accurate gauge and a few minutes a month are most of the job. For the tools that make it easier, see our tire tools guide, and for diagnosing anything that looks wrong, our tire problems guide is the place to start.
Mistakes and warning signs
These maintenance errors shorten tire life and undermine safety.
Checking pressure when tires are hot
A warm tire reads higher and can mask underinflation. Check pressures cold, before the vehicle has been driven far.
Going by looks instead of a gauge
A tire can look fine while being significantly underinflated. Use an accurate gauge every time rather than judging by eye.
Skipping rotations
Front and rear tires wear differently. Rotating them on schedule spreads the wear and extends the life of the set.
Ignoring uneven wear
Wear on one edge or in the centre points to misalignment or incorrect pressure. Correcting the cause early saves the tire.
Neglecting the spare
A spare that has quietly deflated is useless when you need it. Check it alongside the road tires.
Maintenance task and interval
Typical guidance — always confirm the exact figures for your vehicle.
| Task | Suggested interval |
|---|---|
| Check and set tire pressures (cold) | At least monthly and before long journeys. |
| Inspect tires for damage and objects | At every pressure check. |
| Measure tread depth | Monthly and before winter. |
| Rotate tires | Every 5,000 to 8,000 miles, or as specified. |
| Check alignment and balance | After impacts, or if wear is uneven or vibration appears. |
Monthly tire maintenance routine
- ✓Check all four pressures plus the spare, cold, with an accurate gauge.
- ✓Inflate to the vehicle placard figure, adjusting for heavy loads if specified.
- ✓Measure tread depth across each tire and compare positions.
- ✓Inspect the tread and sidewalls for cuts, bulges and embedded objects.
- ✓Look for uneven wear patterns that suggest alignment or pressure problems.
- ✓Note the date so the next check and the rotation interval are easy to track.

Questions readers ask
Short, accurate answers to the questions this topic raises most often. These are answers, not a promise of any search feature.
At least once a month and before long journeys, always when the tires are cold. Temperature changes also affect pressure, so check more often when the seasons turn.
A common interval is every 5,000 to 8,000 miles, but some manufacturers specify differently. Follow your owner's manual and any pattern it recommends.
Not automatically, but it is worth checking if the old tires wore unevenly or the vehicle has had an impact. Correct alignment protects your new tires.
Common causes are a small puncture, a leaking valve, a poorly sealed bead or a porous or damaged rim. Have it inspected rather than repeatedly reinflating.
Yes. Correct pressure, regular rotation and good alignment are the main factors in even wear, and even wear means the set lasts longer and performs more predictably.
