How to Choose Car Tires

Every driver eventually has to buy new tires. Most of the time there’s no big mystery. The old ones are worn out, one got damaged, or you just want something better before a long trip. The headache starts when you actually look at what’s on offer.

Same size, completely different brands, and prices that can go from around €50 all the way past €150. If you’re not particularly into tires, they all look pretty much the same. So where do you even start?

Easiest approach is to forget the brand for a second and look at the car itself. The right tire depends on the size, the weight of the vehicle, the roads you drive on, and how you normally use the car. A tire that works great on a small hatchback can be a poor choice for a heavy SUV or a powerful sports car.

The size on the sidewall actually matters

Before you start comparing Michelin with Pirelli or a premium tire with a cheaper one, check the size.

You’ll usually find it on the sidewall. Something like 205/55 R16 91V is a typical example. First number is the width in millimetres, second is the profile, R means radial construction, 16 is the wheel diameter. The last figures are about load and speed.

You don’t need to memorise any of this. What matters is getting the specification right.

Some cars have more than one approved tire size, especially if they were sold with different wheels. The safest place to check is the sticker inside the driver’s door, the owner’s manual, or the vehicle documents. Just because a tire physically fits the wheel doesn’t mean it’s suitable for the car.

We’ve got a closer look at one of the most popular sizes here: our 205/55 R16 tire guide.

The cheapest option isn’t always the one that saves money

There’s nothing wrong with trying to keep costs down. Tires are expensive, especially on bigger wheels.

The problem starts when price becomes the only thing that matters.

Imagine two tires in the same size. One costs €60, the other €110. Around town on a warm, dry afternoon both can feel perfectly fine. That doesn’t tell you much about what happens when the road gets wet and you suddenly need to stop.

Wet braking is one of those situations where tire quality becomes much easier to notice. Same goes for a quick lane change, a motorway in heavy rain, or a corner taken at higher speed.

The tire is the only part of the car touching the road, so it has a direct effect on braking, steering and traction. A good engine and strong brakes can’t completely make up for poor grip.

That doesn’t mean everyone should buy the most expensive premium tire available. A solid mid-range model can be a very sensible choice for everyday driving. What matters is knowing what you’re buying, not just picking something unknown because it has the lowest price.

Premium or more affordable?

It really comes down to how you use the car.

If you’re doing thousands of kilometres on the motorway every month, you’ll notice things that a person who only drives short city trips barely thinks about. Long distances, rain, higher speeds and a heavier vehicle all put extra strain on the tires.

When people look at premium options, the names that usually come up are Michelin, Continental, Goodyear, Bridgestone and Pirelli. Even within those brands the models vary a lot — some are tuned more for comfort and long life, others lean harder into performance.

For everyday city driving a solid mid-range tire is often enough. Paying a lot more doesn’t automatically make the car better if you never actually use that extra capability.

But if you spend a lot of time on motorways or just want more confidence when conditions get tricky, spending a bit more on a tire with a proven track record can be worth it.

Don’t just compare brands. Look at the specific model.

Sport tires are a different story

Performance tires aren’t trying to do the same job as a regular comfort-oriented touring tire.

Michelin Pilot Sport is one of the better-known ones. Pirelli has the P Zero range, and Dunlop makes sportier options for drivers who want sharper response and more grip. The focus shifts toward handling, braking and cornering. On a twisty road a good performance tire can make a powerful car feel more precise and planted.

The trade-off is real though. They’re usually more expensive, and the softer compounds some of them use tend to wear out faster. That’s just how it is.

On a Porsche, a strong BMW or Mercedes that kind of tire can make sense. On a small city car that mostly sits in traffic, there’s little point paying extra for performance you won’t use.

Portugal changes things a bit

For most cars driven in Portugal, summer tires are the straightforward choice.

The climate stays relatively mild. You get warm weather, dry roads and rain — not long stretches of snow and ice. Summer tires are built for exactly those conditions.

All-season tires can also be useful. They’re a practical option for someone who doesn’t want to change tires during the year and doesn’t regularly drive in very cold conditions.

Winter tires are more relevant if the car is regularly used in colder parts of Europe or on mountain roads where snow and ice are normal.

There’s no universal winner here. The best choice depends on where the car actually goes.

A driver who spends most of the year around Lisbon has very different requirements from someone who regularly drives across Europe in winter.

The European label is useful, but it’s not the whole story

When comparing new tires, the European label is worth checking. It gives information about wet grip, rolling resistance and external noise.

Wet grip is especially useful because rain is one of the situations where tire differences become obvious. Rolling resistance can also have an effect on fuel consumption, although it shouldn’t be the only reason to choose one model over another.

The label is a good starting point, but it doesn’t tell you everything.

Two tires can have similar official ratings and still feel different on the road. Independent tests are useful here, as are reviews from people who have actually used the model.

A good number on the label is a positive sign. It’s just one part of the decision.

Think about your normal driving

There’s no point choosing tires without thinking about the car’s daily life.

A small hatchback used for short trips through the city has very different needs from a large SUV carrying a family and luggage every weekend.

For city driving, comfort, noise and price may be high on the list. With lots of motorway driving, stability, wet grip and durability become more interesting. Drivers who enjoy faster roads or winding routes may care much more about steering response and cornering grip.

The weight of the car matters as well. Larger vehicles need the correct load rating, and the same applies when the car regularly carries several passengers and a full boot.

This is why there’s no single answer to the question of how to choose tires for your car. The tire has to match the way the car is actually used.

Can the front and rear tires be different?

Some cars are designed with different sizes on the front and rear axles. This is particularly common with sports cars and more powerful models. If your car has this setup, stick to the manufacturer’s approved sizes. When all four wheels use the same size, using the same model across the car is normally the easiest solution. At the very least, tires on the same axle should be properly matched.

Mixing completely different tires can change the balance and handling of the car, especially on a wet road.

We also have a separate article about what can cause tires to overheat.

Buying a used car? Look at the tires

Tires are easy to ignore when inspecting a used car, but they can tell you quite a lot.

Start by looking at all four wheels. Are they wearing evenly? Is one tire much more worn than the others? Is the inside edge almost finished while the outside still looks good?

Uneven wear can sometimes point towards an alignment or suspension problem. It doesn’t prove that something is wrong, but it’s a good reason to ask questions and have the car checked.

Age is another thing worth looking at. A tire can still have plenty of tread while the rubber has become old and started to crack.

The four tires don’t necessarily have to be identical either. Owners often replace tires at different times. Still, four completely different models can give you a reason to ask how the car was maintained.

A few minutes with a flashlight and a look at the sidewalls can be more useful than it sounds.

Don’t look only at the tread

Everyone checks the tread first. The sidewall, though, can show just as much. Cuts, cracks, bulges — all of that matters. A bulge is especially worrying because it often means the internal structure took a hard hit.

Potholes cause this a lot. You hit one, keep driving, think everything’s fine, and the damage is already there inside the tire.

That’s why a strange shape or a new vibration is worth paying attention to. If something looks off, a tire specialist can usually tell you pretty quickly whether it’s still safe to use.

Keep the pressure right

Even brand-new tires won’t work properly if the pressure is off.

The correct pressure is normally listed on the sticker inside the driver’s door, near the fuel filler, or in the owner’s manual. The maximum number printed on the sidewall itself is not the one you should just set and forget.

Too little air raises rolling resistance and can push up fuel use. It also changes how the tire wears. Too much air makes the ride harsher and alters the contact patch with the road.

It’s a small job, but checking it regularly makes a difference.

If the car has TPMS, don’t ignore the dashboard warning. We’ve got a separate guide that explains how the system works and why the light can come on. How long should a set of tires last? There’s no single number that fits every car. One set might be finished after 30 000 kilometres, another can easily go twice that far. Driving style, road surface, vehicle weight, the tire compound and how well they’re looked after all play a part.

Tread depth is the obvious thing to watch, but age matters too. A car that barely moves can still end up with old tires. Sun and heat speed up the ageing, especially if the car sits outside a lot.

If you’re not sure how old they are, check the production date on the sidewall. And before a long trip it’s worth having them looked at.

What about buying used tires?

Used tires can cut the cost, but you get less information about their past.

You won’t know if they hit a pothole, were repaired, or spent years stored badly. A tire can look fine from the outside and still have hidden damage.

If you’re thinking about used ones, check the age, the tread and the sidewalls carefully. More importantly, weigh the actual saving against the price of a new mid-range tire.

Sometimes the difference just isn’t big enough to justify the extra uncertainty.

The right tire is the one that fits your car and your life

Once you stop searching for a single model that’s perfect for everyone, choosing becomes a lot simpler.

Start with the correct size and the right ratings. Then think about where you drive, how many kilometres you cover and what actually matters to you — quiet comfort, motorway stability, or sharper grip if you’ve got a powerful car.

There’s nothing wrong with going for a good mid-range tire when it matches your needs. And there’s nothing wrong with paying more for a premium or performance model if you can actually use what it offers.

Before you buy, compare a few options, look at independent tests and check the European label. Most of all, take a proper look at the tires already on the car. They often say more than the price tag does.

In the end only four pieces of rubber connect your car to the road. When something unexpected happens, those are what you have to rely on.
