How to choose the right tyres: the answers
The questions people ask before buying: what to look at, what really matters and what changes from one tyre to another.
When does it make sense to replace only two tyres and where should they go?
You can replace just a pair if the other two are still in good condition. Michelin recommends fitting the two new tyres on the rear axle, even on front-wheel-drive cars: deeper tread at the rear helps clear water and avoid oversteer, that is the rear losing grip, which is harder to control. On the same axle the two tyres must be the same brand and model.

Can I replace just one tyre?
You can if the other tyres have similar tread: according to Michelin, if the difference in wear is not significant it is enough to replace the damaged one, otherwise it is better to replace both tyres on the same axle. On four-wheel-drive cars differences in circumference between the wheels can stress the transmission, so the manufacturer's instructions must be followed. The assessment must be made for the individual car.

Can I mix different brands or models on the car?
On the same axle two tyres of the same brand and model must be fitted. Between different axles you can use different brands or patterns, but Michelin advises against mixing summer and winter tyres. On four-wheel-drive cars, using tyres different from those recommended by the manufacturer can prevent the drive system from compensating for the differences and cause damage.

How do you read comparative tyre tests?
Check that the test covers the same size and category (summer, winter, all-season) and that it is recent, because models are updated. Look at the criteria that matter to you: braking in the wet and dry, noise, consumption, wear. Check who ran the test: motoring clubs and specialist magazines, such as ADAC or TCS, publish their methods. The overall score depends on the weight given to individual criteria.
Are retreaded tyres safe?
Retreaded tyres are governed by specific rules: UNECE Regulation No. 108 for cars and No. 109 for commercial vehicles. They must carry the approval mark. They are common on lorries and buses, much less on cars. The main risk depends on the starting casing: quality is not as uniform as in a new tyre. For a car in normal use the most common choice remains a new tyre.

How do you run in new tyres?
In the first kilometres a new tyre may have slightly lower grip: Continental explains that a lubricant used to extract it from the mould remains on the tread and wears off with use. That is why it recommends moderate driving at the start, avoiding sudden acceleration and braking and keeping more distance from the vehicle ahead. After fitting it is also a good idea to check the inflation pressure.

Do new tyres need balancing too?
Yes: every wheel complete with tyre must be balanced when fitted, even if the tyre is new, because rim and tyre have small differences in weight. An unbalanced wheel causes vibrations in the steering wheel or seat and uneven wear. Balancing is done with adhesive or clip-on weights on the rim. Our WhatsApp quotes include fitting, balancing and disposal of the old tyres.
How many kilometres do tyres last?
It depends on model, driving style, load, pressure and alignment: there is no figure that is valid for everyone. Sports tyres with a soft compound generally last less than those designed for longevity. To extend life you need correct pressure, alignment in order and wheel rotation where permitted. For a fair comparison look at independent tests, which include wear measurement.
What affects a tyre's noise?
Rolling noise depends on the tread pattern, the compound, the width and the road surface. The EU label gives external noise in decibels and a class (A, B or C), measured under test conditions: it is a useful indication but does not describe the noise perceived inside the cabin, which also depends on the car.
Do tyres affect fuel consumption?
Yes, through rolling resistance: compound and structure affect the energy lost while the tyre rolls. The EU label gives the energy efficiency class from A to E. Pressure matters too: an under-inflated tyre increases rolling resistance. To choose, it is best to weigh all the items on the label together, starting with wet grip.
Are sports tyres (UHP) suitable for everyday use?
They can be, if the car requires them or you want sporty driving. UHP (Ultra High Performance) tyres are designed for high grip and quick response, with high speed codes (such as V, W, Y). In return they may wear faster and offer less comfort; summer models suffer in the cold. For normal use, if the specified size allows it, a touring tyre is often better balanced.
What tyres should I choose for city use?
For city use what counts is comfort, resistance to kerbs and potholes, low rolling resistance and good wet braking, not top speed. Tyres with taller sidewalls and a touring model are often suitable. The choice depends on the approved size, the type of car and the climate. On our site the size finder shows the sizes by car make and model.
