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.

29.07.2025 from Tom
These tyres in my rear wheel drive BMW are grippy in the dry, but leave me yearning for more in the wet. The car will &quot;step-out&quot; if I punch it whilst the road is even midly damp. My tracking was done at the same time as having these fitted so that is not a factor. The car will also step out if the road is more greasy looking.

03.03.2025 from David Dyson
Mature elderly, x competition experience so not a plodder by any means, retired now so on a budget, these tyres meet that, but excellent performance for the price, also its a must for me that al my tyres are of the same make and compound, went a profile section up from manufactures recommendation, very noticeable increase in grip and handling, only slight negative, possibly due to the excellent torque of my engine ( Turbo Diesel ) and my driving style rather than the tyres, but grip on initial acceleration from stationary even in the dry ( obviously worse in the wet ) definitely not the best, so suspect compound compromise, but nothing serious.
27.05.2021 from fred heath
I like quiet and comfort when driving. These tyres provide that experience as well as a noticeable increase in economy. Being retired I do not have to go out in all weathers but when caught out by the weather these tyres perform well although snow, as might be expected, is a bit of a trial. Despite this I would look for these tires again as they suit my driving style and needs.
13.09.2020 from Marek
Generally... There are no surprises with these tires so far, they work great on wet surfaces, they are quiet, it&#39;s ok. I&#39;m waiting for winter and the first snow.
02.06.2020 from Paul W
Having fitted these tyres all round, they have transformed the car. I used popular well known Japanese brands previously which I had never truly been happy with. I fitted the new tyres and instantly the car felt better, more responsive and considerably smoother. The noise from the tyres was incredibly quiet and I was surprised at how much noise the previous tyres had actually generated. I have also noticed how much better the tyre grips under acceleration and the steering was sharper and more responsive to the touch. There also feels less rolling resistance on the road. I have noticed the tyre pattern looks far better for displacing water and whilst only currently driving in slightly wet conditions, again the feel and response instill a feeling of confidence and safety with good firm grip. Overall I&#39;m greatly impressed with the tyre and would have no hesitation in recommending for performance, grip and safety.

these tyres are perfect for my type of driving and are excellent value for money
29.09.2015 from Phil Hunt
Superb value for money. Outperform run flats in every respect, especially comfort.
07.09.2015 from Wayne
This tyre was chosen for the rear, a 225/45 was fitted to the front. Being lowered on eibach suspension and on aftermarket wheels this tyre set up brought back the progressive feel of the standard car as well as the ride comfort. Wheels are 8.5 front and 9.5 rears.
