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.
16.02.2023 from Alasdair
A solid tyre I&#39;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.
26.02.2022 from Suki Nandhra
Great tyres and the reason why I always come back to Conti&rsquo;s
24.03.2021 from N Moss
More comfortable than a lot of winter tyres we have had. A bit noisy but not too bad. Fuel economy better than most.

Steering and wet road handling improved since replacing the standard tyre fitment.
21.05.2019 from Jane
I bought these as they rated well performing across the board. Not top in anything but above everything that was top in at least one area. The wet grip and braking is fantastic. Performed well throughout the cold months but we had no snow this year to test them. On warm dry roads the compound or pattern does not allow for an aggressive driving style but I never intended to keep them on in the summer so this was irrelevant to me. They make a noise like driving through standing water in the wet which is strange at first but I wouldn&#39;t say generally they were any noisier than my Eagle asymmetric 2 that they replaced. Did everything I expected from them and will be re fitting them come the winter.

Car Driven : BMW 425D 225Hp . Quite quietly from the start until the first 10,000 km they kept a relatively low noise level until the end of their lives. Relatively comfortable especially considering that is a runflat tire. The tire tread still retains its original groove and design but has significant wear points on both edge and there are some small tire detachments. In the few rains we have in Greece it never had a hadling problem or breaking and did not create any feeling of insecurity. in short it is a good quiet tire ROF tire, comfortable and efficient in fast driving.
31.12.2021 from Stuart
Big improvement on the OEM fitted brand. More refined, quieter and more confident grip in both wet and dry. Fitted full set; 215/45R17 in front and 245/40R17 in rear, as standard spec. Only driven on road (A and B roads and some motorway), no tracking. Hard to fault for this purpose.
16.07.2021 from Rok Sharma
I drive fast and furious when required or slow and deliberate in slow traffic! I used these tyres on my 5 series BMW 525iSE and were superb! Now on Mrs Peugeot 308 hdi and pretty good!

26.09.2020 from Steve Bez
The ne thing with my car is the torque and how easy it is to get the wheels to lose traction. Coming from Michelin PS2 Sports I thought I would try out the Goodyear. One thing is obvious - the grip is immense. Way better than the PS2&#39;s which were quite old and maybe had hardened up a bit but the GY&#39;s were a fabulous choice and would definitely get again, just hope the Asymmetric 2 remains available. Don&#39;t drive much when wet but still better grip all round from these over the PS2&#39;s.
02.02.2020 from Dave
I was really impressed with these tyres, the volvo v60 D4 is a heavy car with 192bhp 400nm of torque. 235/40/18 Winter has been very wet and i would describe my driving style as quick, with moments of very fast! The grip in all weather conditions is sensational, both dry and wet there is no tyre slip even with a spirited drive. I have also tested the grip limits at low speeds around roundabouts and there is a lot more grip available than i thought there would be in the wet. Tyre life seems good after 4000km and i do mainly a mix of country lanes and dual carriage way day to day. I am very impressed and will buy these tyres again!
