Car tyre care in India: pressure, cleaning, cracks and when to replace
Ownership
·6 min read
Tyres get less attention than paint, yet they decide how the car brakes, steers and grips on a wet Kolkata road. Indian conditions — heat, potholes, overloading, long periods parked and monsoon water — are hard on them. A few minutes of attention each month, and the right way of cleaning them, keep them safe for longer.
Key takeaways
Check pressure monthly with the tyres cold, using the figures on the door frame or in the manual — not the number on the tyre sidewall.
Tread wear indicators show when a tyre needs replacing; uneven wear points to alignment or pressure problems.
Sidewall cracks come from age, sun and ozone; deep cracks or bulges mean replacement.
Clean tyres with a dedicated brush and cleaner; use water-based dressings and keep them off the tread.
Tyres age even if unused — check the manufacture date when buying and on older cars.
Pressure: the most important habit
Correct pressure affects braking distance, grip in the wet, fuel efficiency, how evenly the tread wears, and how well the tyre resists pothole damage. In India, under-inflation is common — partly because tyres lose a little air every month, and partly because many people check only when a tyre looks visibly flat.
Use the right number. The recommended pressure is on a sticker in the driver's door frame, inside the fuel flap or in the manual. It often differs front and rear, and for a fully loaded car. The number moulded on the tyre sidewall is the tyre's maximum, not the target.
Check cold. Tyres heat up when driven and pressure rises. Check before driving, or after the car has stood for a few hours.
Use a reliable gauge. Petrol pump gauges vary. A small digital gauge in the glovebox is cheap and accurate.
Check monthly, before long trips, and before carrying a full load of passengers and luggage.
Do not forget the spare. A flat spare is discovered at the worst moment.
Nitrogen filling, offered at many service centres, loses pressure slightly more slowly than air but still needs checking. It is not a substitute for monthly checks.
Tread: how much is left
Tread grooves carry water away from under the tyre. On a wet Kolkata road in the monsoon, worn tread means a much higher risk of aquaplaning and longer braking. Every tyre has tread wear indicators — small raised bars at the bottom of the main grooves. When the tread surface is level with them, the tyre is at its legal and safe limit and should be replaced. Many drivers replace earlier, before the monsoon, for better wet grip.
Reading uneven wear
Wear pattern
Likely cause
Both edges worn more than centre
Under-inflation
Centre worn more than edges
Over-inflation
One edge worn
Wheel alignment out
Patchy, cupped wear
Worn suspension or wheel imbalance
Flat spot
Hard braking with locked wheel, or long parking on a flat tyre
Uneven wear is the tyre telling you something about pressure, alignment or suspension. Fixing the cause saves the next set.
Sidewalls: cracks, bulges and cuts
Look at both sidewalls of every tyre once a month, turning the steering to see the inner side of the front tyres.
Fine surface crazing — a network of shallow cracks — is a sign of ageing rubber, made worse by sun, heat, ozone and harsh chemicals. Monitor it.
Deep cracks, especially in the grooves or near the rim, need a tyre specialist's inspection.
A bulge or bubble means internal damage, usually from a pothole or kerb impact. Replace the tyre; it can fail suddenly.
Cuts that show cords or fabric mean replacement.
Kolkata's potholes in the monsoon are a common cause of sidewall bulges. Slow down for them and avoid hitting kerbs when parking.
Age: tyres expire even unused
Rubber ages whether the car is driven or not. A tyre with plenty of tread can still be unsafe if it is old and hardened. Every tyre has a manufacture date code on the sidewall — a four-digit number showing the week and year. Check it when buying new tyres (avoid old stock), and on cars that are driven little, where tyres often age out before they wear out. Many manufacturers and experts recommend closer inspection as tyres pass several years old.
Cleaning tyres properly
Clean tyres look good, and cleaning them lets you see cracks and damage. Tyres hold a surprising amount of grime: road dirt, brake dust and old, browned dressing.
Clean wheels and tyres before the paint, with separate brushes and cloths. Brake dust is metal and must never reach the paint.
Spray a tyre cleaner or a mild all-purpose cleaner onto the sidewall.
Scrub with a stiff tyre brush. The foam turns brown as old dressing and grime lift.
Wipe off, and repeat until the foam stays white.
Let the tyre dry before applying any dressing.
Tyre dressing: the safe way
Dressings make tyres look black and new. Used carelessly, they cause problems:
Prefer water-based dressings. Some solvent-based, high-gloss silicone products can dry rubber over time and attract dust.
Apply with an applicator, not a spray. Overspray lands on wheels, paint and brakes.
Never on the tread. Dressing on the tread reduces grip.
Wipe off excess, or it will sling onto the paint as the wheel turns.
Satin finish looks cleaner than wet gloss and attracts less dust.
Rotation, alignment and balancing
Front tyres usually wear faster than rear on front-wheel-drive cars. Rotating them at the interval in your manual evens out wear and extends the life of the set. At the same time, have wheel alignment checked if the car pulls to one side or the tyres show uneven wear, and balancing checked if the steering vibrates at speed. Kolkata's potholes knock alignment out more often than people expect.
Punctures and repairs
Most car tyres in India are tubeless, and a nail in the tread usually causes a slow leak rather than a sudden flat — which is why a monthly pressure check often finds punctures before they become a problem. A puncture in the central tread area can normally be repaired properly by a tyre shop with a plug-patch from the inside. Punctures in the shoulder or sidewall generally cannot be repaired safely and mean replacing the tyre. Roadside "mushroom" or string plugs are a temporary fix to get you to a shop. If you drive on a tyre that has gone very soft, have it inspected even after re-inflating; running flat damages the sidewall internally in ways you cannot see.
Buying new tyres
When replacing, match the size and load and speed ratings in your owner's manual, replace in pairs on the same axle at least, and check the manufacture date code so you are not sold old stock. Ask for wheel balancing and an alignment check with the new tyres. For city driving in Kolkata, wet grip matters more than outright performance; tyre labels and reviews of wet braking are worth reading. Keep the old tyres' wear pattern in mind: if they wore unevenly, fix the cause, or the new set will go the same way.
Parking and storage
Avoid parking with a tyre pressed against a kerb or on sharp debris.
Park in shade where possible; sun ages rubber.
For cars that stand for weeks, keep pressures correct and move the car occasionally to avoid flat spots.
Keep oil, fuel and solvents away from tyres in the parking.
Monsoon checklist
Before June: check tread depth and replace tyres near the limit; check pressures; inspect for cuts and bulges. During the rains: slow down for waterlogged stretches — a hidden pothole under water is a common cause of sidewall damage. After the rains: inspect again. See post-monsoon care.
Tyres in every wash
Tyre and rim eco-shine is part of every Car Ninza waterless wash, using separate brushes and cloths so wheel grime never touches the paint. Our crew will also point out anything worrying they notice — a bulge, a nail, a very worn edge — so you can have it checked. For the wheels themselves, see alloy wheel cleaning.

Frequently asked
Questions on this topic
What should my car tyre pressure be?+
Use the pressures on the sticker in the driver's door frame, fuel flap or owner's manual, measured with the tyres cold. The maximum pressure printed on the tyre sidewall is not the recommended pressure.
How often should I check tyre pressure?+
At least once a month, and before long trips or carrying a heavy load. Check the spare too.
How do I know when to replace my tyres?+
When the tread is worn down to the tread wear indicators — small raised bars in the grooves — or if there are deep cracks, bulges, cuts, or exposed cords. Ageing is also a factor; many experts suggest inspecting tyres closely once they are several years old.
Why are there cracks on my tyre sidewall?+
Usually age and exposure to sun, heat and ozone, sometimes worsened by low pressure or harsh chemicals. Fine surface crazing is common on older tyres; deep cracks need a tyre specialist's inspection.
Is tyre shine bad for tyres?+
Some solvent-based, silicone-heavy dressings can dry rubber over time and sling onto paint. Water-based dressings are gentler. Never apply dressing to the tread.
How do I clean car tyres?+
Use a dedicated tyre cleaner or a mild all-purpose cleaner with a stiff tyre brush, scrub the sidewall until the foam stops turning brown, wipe off, and let dry before any dressing.
How often should tyres be rotated?+
Follow the interval in your owner's manual — often every 5,000 to 10,000 km — and at the same time have the wheel alignment and balancing checked if the car pulls or the steering vibrates.
Does Car Ninza clean tyres?+
Yes. Tyre and rim eco-shine is part of every wash, using separate brushes and cloths so brake dust and tyre grime never reach the paint.
