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.

These BF Goodrich All Season 4 grip tyres are not only unbeatable in the snow, they give fantastic mileage at a very reasonable price. I run them all year round on my Model 3 Performance - they have lasted around 30,000 miles but are now ready for changing and if I can get them delivered (thank you Brexit!), I will have four more exactly the same!

The tyres have exceeded my expectations for grip and longevity, only criticism is they are noisy.
04.05.2019fromStuart Fraser
Very pleased with them,I have used them through the winter and we have not had much snow, but have used them whilst being in 4 wheel drive in icy conditions The majority of my driving is city and motorways.

Steering and wet road handling improved since replacing the standard tyre fitment.
21.05.2019fromJane
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.

This is the second set of the same tyres, and yes they hold the road well. When you have 20 something inch of rubber on the road they can really hold there own. The Which magazine holds Bridgestone to high esteem.
13.10.2020fromBowber
Great tyres, good grip especially in wet, feel safe! Noise isn’t too crazy, hopefully get some decent mileage out of them

Much better in the wet than Dunlop tyres that were on the car.

OEM tyre for car. Provide amazing grip in a 4 wheel drive lightweight sports car. Cornering at speed is amazing, braking too.
