Summer tyres - optimal grip guaranteed!
On dry roads or mild weather, your tyres have to face some increased demands and must always meet safety standards. Compared to winter tyres, the rubber mixture of the summer tyres is harder, even in high temperatures. Default rolling resistance and wear are smaller, resulting in a greater lifespan, comfort and increased stability. Choose now from our offer your summer tyres at an affordable price. Our portfolio includes a wide range of tyre brands
 
Identify the size of your tyre
The exact dimensions of a tyre can be found on the sidewall printed mark. The graphic shows how to read properties and dimensions of the tyre:
 
/
SPEED INDEX:
The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.
 
Load Index
Permissible maximum axle load per tyre in kg. To be found in the registration certificate or vehicle registration document or read directly from the tyre (two-digit number). It is permitted to fit a tyre with a higher load index.
 
Driving safety despite puncture
Runflat tyres are puncture-resistant tyres with reinforced sidewalls. This creates the so-called run-flat property. In the event of damage, this allows the vehicle to continue driving up to a distance of approx. 100 km (and even beyond depending on the product) at a maximum speed of 80 km/h, even if the pressure has been completely lost. Run-flat tyres even prevent the tyre rubber from jumping off the rim in the event of a loss of air pressure. A flat tyre is therefore still a flat tyre, but it loses some of its drama. Note: All run-flat tyres are marked with the symbol "RSC" (Runflat System Component) and may only be fitted in vehicles with a functioning air pressure control system!
 
Tyres with increased load capacity
Reinforced tyres are designed for higher loads than normal tyres. They can be identified by the designation 'RF' (reinforced) or also 'XL' or 'Extra Load'. They are used on vans, minibuses, off-road vehicles, etc. However, their mounting alone does not automatically result in higher load capacity but also requires a correspondingly higher air pressure. Furthermore, the load capacity index specified in the vehicle documents continues to apply.
 
Tyres with extra high load capacity
The "C" in the term C tyres stands for "commercial". These tyres are specially designed for commercial vehicles. These can be, for example, lighter trucks, delivery vans, flatbed trucks or panel vans. In other words: vehicles that have to move higher loads at a comparatively lower speed. The multi-ply reinforced C tyres are therefore even more load-bearing than reinforced tyres.
 
Mobility-optimised tyres
A tyre with a sealing layer on the opposite side of the tyre tread. In the event of a puncture (e.g. by a nail), this layer blocks any loss of air, even if the foreign body causing the puncture is still in the tyre. It is not necessary to stop or change the tyres immediately at the roadside.

Many Man miles, 252,000 in the car.
16.02.2023fromAlasdair
A solid tyre I've refitted to the car several times already. Excellent grip on wet and dry and more comfortable than the SportContact they replaced with marginal difference in performance. Only difference felt was feeling marginally more tyre wall flex if driving very hard in corners but a lovely balance for comfort and excellent grip. They are slightly louder than other tyres which is a minus but worth it for overall performance. Very predictable behaviour wet and dry. Only other downside is Conti shipping tyres with slightly lower than average new tread which makes it a bit more expensive over the life than similar priced tyres from other brands.
26.02.2022fromSuki Nandhra
Great tyres and the reason why I always come back to Conti’s
24.03.2021fromN Moss
More comfortable than a lot of winter tyres we have had. A bit noisy but not too bad. Fuel economy better than most.

Really poor wear. Would not buy again. Was getting near 20k miles on cheaper brands. Expected more from Firestone
21.01.2020fromJames
These tyres perform well, they're comfortable and they're quiet, but they're fragile and wear too quickly. They get punctured and damaged really easily and don't last as long as I would expect. I've had two full sets of these tyres but after yet another puncture I'm sick of constantly having to change them so I've had them all replaced with another brand. I won't buy these again and I don't recommend them.

Very good Tyre, low noise, very good in the wet.

09.11.2025fromNeil McTear
Far better grip than the Falkens that came with the car, although they still had lots of tread left, they were old and on removal it was found the sidewalls and beads were perished, and were the wrong size. Toyo are current the only manufacturer producing 205/45-15's and these had previously been unavailable for the previous decade, the improvement in both grip and roadholding is impressive, can't comment on wear yet due to limited mileage, fuel consumption difference - I haven't checked.
30.05.2022fromDavid Hardiman
Huge difference with the new Toyo Tires compared to the older ones I had on the car. These are the best tires I have ever used.
09.12.2019fromSebastian Dysarski
Good tire soft side wall so corners are average. But overall good price was okay wouldn’t pay more
14.11.2019fromJoe
I drive an SW20 MR2 on (almost) original tyre sizes (Rear 225/50/15 and Front 205/50/15), so my choice is limited. For over a decade I've used the original Proxes as they were pretty good all-rounders and good value. The new version are very good in the dry - communicative and grippy, you can feel the back end start to let go and everything is progressive and fun. However, the tread pattern gives me zero confidence in the wet as the pattern is in a v direction on one side of the car and a ^ direction on the other. Not a mistake, the "Outside" markings insist this way round. This has to have a huge impact on clearing standing water as the tread is reversed on one side of the car, so I have zero confidence in the wet as each side of the car will behave differently. Bring back the old style that were ^ all round please!

24.07.2025fromMatthew A McCrae
These tyres give me everything I ever needed from a tyre. Not only are they brilliant in the open road. The confidence they allow when cornering is quite remarkable. I have learned to trust them as I do the Michelins on my motorcycle.
22.07.2024fromMike Greenfield
Excellent amount of grip yet keeping some subtlety even though they are 32psi as recommended. Tyre wear seems reasonable given the performance level and economy appears as good as any. I would buy these again when it becomes necessary. Excellent!
12.04.2024fromMr Badger
We already had two of these tyres fitted to the car so when the other two needed replacing we matched them. They perform well in all conditions wear evenly and are good value. Would definitely buy again for a small city car.

Noted an increase in millage from tje start, also noticed a noise reduction while driving. Good grip and reduced roll. All in all a good upgrade for electric cars.
10.06.2021fromAnthony Hibbs
I bought these tyres as they are the only ones on the market that claim to be specifically designed for electric vehicles and are carbon neutral in their manufacture. Lots of claims made by Michelin regarding low noise levels, grip, wear and increased range. I can confirm that the tyres live up to these claims in all respects. I have driven around 1200 miles in mixed road and weather conditions and have been very impressed. My eGolf was always a quiet car, but now it’s almost silent with little or no road noise below 50mph. Braking and handling in wet or dry, good roads or bad, is exceptional. My average range previously was around 150 miles from a full charge, now it’s 160 miles, remarkable. I absolutely recommend these tyres for electric vehicles.

16.12.2025fromEdward Nunn
these are on my track/fun car and replaced the 20 year old tyres on it which came with the car, they completely changed the performance of the car, for the better, they grip exceptionally, especially when set to optimum pressure for the conditions, and hold traction under very heavy braking. They are as described a dry weather tyre with the ability to just about cope in the wet, and my experience is of dry track days with a very wet drive cross country the day before a track day which was ok, although i could feel a massive loss in traction crossing white lines on the motorway, and the morning before a track day driving through wet cool lanes which required a huge amount of care and attention not to end up in a hedge.
