Key takeaways
- Typical A4 tyre sizes run from 205/60 R16 on SE to 225/50 R17 on Sport, 245/40 R18 on S line, and 245/35 R19 on S4 and larger alloys.
- The A4 is an executive saloon or Avant, so prioritise comfort, refinement and quiet cruising over outright sportiness.
- On quattro models, keeping all four tyres matched in size and tread protects the four-wheel-drive system and keeps wear even.
- Mobile fitting keeps a working exec car on the road, with fitting done at home, the office or the roadside.
The Audi A4 is a benchmark executive car, sold as a smooth saloon and a practical Avant estate, and prized for its refined motorway manners. The right tyres keep that comfort and composure intact. Your best choice depends on whether you have a comfort-biased SE, a firmer S line, a load-carrying Avant, or a quattro model. This guide covers the typical sizes, the comfort-versus-sport decision, how quattro affects tyre choice, and why mobile fitting suits a busy owner.
What are the best tyres for an Audi A4?
The best tyres for most A4 models are premium or quality mid-range touring tyres with low noise, a comfortable ride and strong wet grip, in your correct size. As an executive car built for refined, high-mileage cruising, the A4 rewards a quiet, composed tyre far more than a cheap, firm one. Quattro and S line models have a few extra considerations.
What tyre size does an Audi A4 use?
A4 tyre sizes vary by generation, engine and trim, so check your own sidewall or the placard inside the driver's door before buying. As a guide, SE and base cars often run 205/60 R16, Sport trims commonly use 225/50 R17, S line moves to 245/40 R18, and the S4 or large-alloy versions can run 245/35 R19.
| Typical A4 trim / model | Common tyre size (check yours) |
|---|---|
| SE and base cars | 205/60 R16 |
| Sport | 225/50 R17 |
| S line | 245/40 R18 |
| S4 / large alloys | 245/35 R19 |
To decode the size code plus the load and speed ratings you must match, see our guide on what the numbers on your tyre mean. The Avant estate can carry more weight, so its correct load rating matters when the boot is full.
What should an A4 owner prioritise?
An A4 owner should prioritise comfort, refinement and wet grip, because this is a car bought for relaxed, high-mileage driving. Low rolling noise keeps long journeys quiet, a composed tyre preserves the smooth ride, and strong wet braking keeps a heavier exec car safe. Good tread life then keeps cost per mile sensible over big annual mileage.
- Comfort and low noise, central to the A4's relaxed cruising character.
- Wet grip, essential for safe braking in a heavier executive car.
- Tread life, keeps cost per mile down on high motorway mileage.
- Correct load rating, important on the Avant when carrying a full load.
For a comfort-focused A4, a premium touring tyre pays back in quietness and longevity over the miles many owners cover. A quality mid-range tyre is a sensible alternative on lower-value cars. To plan the spend, our guide on how much new tyres cost in the UK gives a realistic idea before you commit.
It is also worth checking for an original-equipment approval marking when you buy. Audi frequently specifies tyres carrying an AO mark, tuned to match the A4's refined ride and steering, and many owners like to stay with an approved tyre on a car sold on comfort. It is not a legal requirement on a replacement, so a good non-marked premium tyre is fine too, but the mark is a useful pointer if you want a like-for-like fit.
Comfort or sport tyres on an A4?
Most A4 owners are better on comfort-biased touring tyres, because the car's strength is refined cruising rather than track-style handling. A touring tyre keeps the cabin quiet and the ride supple, which suits SE and Sport trims on their higher-profile wheels. Sport-focused tyres add a little dry bite but often at the cost of noise and comfort.
The exception is the S line and S4 on low-profile 18s and 19s, where a sportier tyre can complement the firmer setup and higher speed rating. Even then, in our experience many drivers prefer a premium tyre that leans towards comfort, because it makes daily and motorway use far more pleasant. Match the tyre to how you actually drive, not the badge.
How does quattro affect A4 tyre choice?
Quattro four-wheel drive makes matched tyres more important, because uneven tread across the axles can stress the centre differential over time. On a quattro A4, Audi generally wants all four tyres at similar size, brand and tread depth. That means replacing in fours when they are worn, or at least keeping wear as even as possible with regular rotation.
[UNIQUE INSIGHT] Many A4 buyers do not realise their car is quattro until a fitter points it out, then wonder why replacing one odd tyre is discouraged. If yours is quattro, plan ahead: rotate tyres at service intervals so they wear together and can be replaced as a set. Front-wheel-drive A4 models are more forgiving and can be replaced in matched pairs.
Two tyres or four on an A4?
On front-wheel-drive A4 models you can replace in pairs, fitting a matched set across an axle, usually with the newer tyres moved to the rear for stability. If only the fronts are worn, that is common because they steer, brake and drive. Keep both tyres on each axle the same brand and pattern for balanced grip.
On quattro A4 models, aim to keep all four tyres closely matched, which often means replacing all four together or maintaining even wear through rotation. Our guide on whether to replace two or all four tyres covers the decision, and checking your tread depth tells you how close the rest are to the limit.
Are all-season tyres a good fit for an A4?
All-season tyres suit many A4 owners well, because the car covers big mileage all year and rarely gets a seasonal tyre swap. A good all-season touring tyre grips safely in summer and gives much better traction in cold, wet and light snow than a summer tyre, which is reassuring on early-morning commutes through winter.
The trade-off is a small loss in dry summer sharpness compared with a dedicated summer tyre, though modern all-season tyres have narrowed that gap and many are impressively quiet. On a quattro A4 that already handles poor weather well, all-season rubber adds a useful extra margin. For the S4, a proper summer or performance tyre still makes more sense when you drive hard.
How can you make A4 tyres last longer?
You make A4 tyres last longer through correct pressures, accurate alignment and regular rotation, which matters even more on quattro cars where even wear keeps the four-wheel-drive system happy. Under-inflated tyres wear at the edges and burn extra fuel, so check pressures monthly against the door placard, remembering the higher setting when the car is fully loaded.
Alignment stops uneven wear that can scrap a tyre early, and it is worth checking after any firm kerb strike. On a quattro A4, rotating tyres at service intervals helps all four wear together so they can be replaced as a matched set. Smooth driving and steady motorway cruising, where the A4 is happiest, also stretch tread life over the miles.
Why mobile fitting suits A4 owners

Fast Tyre supplies and fits A4 tyres at your home, office or roadside across London and central England, usually within 30 to 60 minutes, through our mobile tyre fitting service.

Frequently asked questions
It depends on the generation and trim. Common sizes include 205/60 R16 on SE, 225/50 R17 on Sport, 245/40 R18 on S line, and 245/35 R19 on the S4 or large-alloy cars. Always confirm against your own sidewall or door placard, as wheel options vary widely.
Most A4 owners suit comfort-biased premium touring tyres, because the car excels at quiet, refined cruising. Sport tyres add dry bite but often more noise and firmness. Even on S line trims, many drivers prefer a premium tyre that leans towards comfort for daily and motorway use.
Yes. On a quattro four-wheel-drive A4, Audi generally wants all four tyres at similar size, brand and tread depth to avoid stressing the drivetrain. Replace in fours when worn, or rotate regularly so the set wears evenly. Front-wheel-drive A4 models can be replaced in matched pairs.
The size is usually the same for a given trim, but the Avant estate can carry more weight, so the correct load rating matters when the boot is loaded. Check the door placard and fit tyres that meet or exceed the specified load index, especially if you tow or carry heavy loads.
Yes. Fast Tyre brings mobile tyre fitting to your home, office or roadside across London and central England, usually within 30 to 60 minutes. We carry the common A4 sizes and fit, balance and remove the old tyres on the spot, so the car stays working and you skip the garage.
