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.

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'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.

I have never triggered the ABS in 8 years of using this tyre, except when testing the surface, and have always felt confident even on wet ice! Great tyre, summer and winter.

Good tyres but not as good as the Michelin pilot sport 4. Will be going back to the sports.
04.12.2019 from Ali
I am a High mileage driver covering all roads day and night. This is a premium summer tyre made for dry grip and wet braking. Out of a budget , midrange and premium I’ve noted , the cheapest gives me around 6000 miles. The mid ranges cover around 12000 miles and premiums last around 18000 miles. In terms of grip it always has to be premium. These are also much quieter than budget tyres. I’ve covered 25000 miles of hard driving with these tyres and they still have around 3mm left. This is the second summer I’ve purchased these tyres. Good on price as well as grip

07.10.2023 from Simon Hall
Amazing tyres, grip is excellent, comfort and noise are excellent. the only thing i can fault is that the wear isn't anything special. Down to 4mm after 6000 miles. My tyre size is 245/35R18 but tyretest will not let me add the correct size above.
10.08.2023 from DanB
Excellent tyres chosen via the reviews by Jon @ tyrereviews.co.uk - they faired very well against the likes of the Michelin PS5s and at the time of buying (Feb2023) the Goodyears were £250 cheaper than the PS5s; but more or less neck & neck with them in the tyre review! That swung the decision for me, more so with the money saving!

07.02.2022 from Spiros
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.
