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.

Tyres optimised for electric vehicles.
Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

Original equipment quality: optimum adjustment to the vehicle
Tyres with a special OEM marking on the sidewall, e.g. "MO" for Mercedes-Benz, were developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been homologated by the vehicle manufacturer and are a perfect match for a specific model. They have been specially designed to highlight or further improve the performance characteristics of the car in question, thus representing the culmination of a state-of-the-art fine-tuning process that perfectly complements the latest technological developments in the automotive industry. Tyres with manufacturer's markings can of course also be used on other vehicles.

The tyres are Porsche recommended for my car, so it was best to fit the correct tyre, as it would have had at factory. My car had covered only 6900 miles when I purchased it. The original tyres were on the car.

Really good gripping tyre well worth the extra pennies :)
09.08.2014fromAndyH
Always a good idea to but the best tyres you can and these are great. Only downside is road noise which can get irritating at times
24.05.2013fromRoddie
Much more traction offered from these tyres than previous 255/40 R18 Michelin Pilot Sport 2 or the Pilot Sport 1. No feeling of poorer ride quality despite lower profile. An unexpected big jump in overall performance and the traction control light barely appears at all now- compared to all the time out of junctions with sharp left turns. Must be better compound and/or tyre carcass construction.

By the far the best tyre I've ever had on any car. The grip, particularly in the dry, is outstanding- endless grip really. It gives you such a responsive turn-in, and then the confidence and ability to push for the limit...which you may or may not eventually find. Very safe in the wet too and comfort and noise is excellent. Wear seems reasonable as well. I can't recommend them highly enough. Will only ever be purchasing these again, unless Michelin develop an even better tyre..
17.09.2015fromGordon
I bought these tyres to improve Grip on the previous Dunlops and they have been very good. The wet grip is significantly improved and am very happy with them. They are a bit noisier but ride quality is unchanged. They perform very well under all conditions but can still break away in the wet, but with 510bhp not surprising! They are a big step up in performance from the Dunlops and the Pirelli P0s I have used before. Highly recommend them!

Great tyre for performance cars!!
31.10.2014fromdavid duro
They are very good. I usually run Bridgestone pzeros.. But feel after driving in them these are better.

Used purely as a track tyre. Super focused, brilliant feedback in all conditions. Really competent in the wet as they give huge amounts of feedback and never just go, even when there&rsquo;s standing water on track. Wear is pretty good, I&rsquo;ve done 3 hard track days, one of them being bone dry and they&rsquo;ve held up well. Rears are in great condition and expect they&rsquo;ll last multiple days out. Fronts should do several more days out before changing.
