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.

03.05.2023fromMr Shane Harris
I had always purchased branded tyres for my cars, particlulary cars that are quick/nippy. I was recommended these tyres by fellow users on Audi forums etc and I must say that these have been brilliant. Road noise is quite, grip is really good both wet and dry and they are wearing pretty well. For a fraction of the cost of premium tyres that were supplied i will defiantley be buying these again in the future.

Very good Nordic winter tyre, the best on ice there is.

Best winter tyres I've had. Great grip in the snow and really good on cold roads and in the rain. Have performed well now that it's started warming up. Size (not listed on the Dropbox) 245/40/18

08.06.2026fromJ Amin
This is the second time I have bought a full set of these tyres. I mostly drive on motorways, country roads and off road. My fuel efficiency went up when I put on my first set. The ride is more comfortable and the grip is excellent in dry and wet weather. They have performed well on snow. Despite being all weather the rate of wear is very good. I would definitely buy them again.
18.09.2024fromErsan
My tyre size was 205 55 16 but not in the list! Unbelieveble in wet surface but average on dry breaking. Good aquaplanning and snow traction. Good comfort but average noise.
06.03.2024fromViktor
Tires keep the vehicle nicely on the road, no traction problems. On ice British roads they perform great no problems stopping or going.
12.01.2022fromScott
I'll be honest I've never purchased all season or winter tyres before, I've always made do with mid range to premium summer tyres. During winter I've very rarely struggled in snow with summer tyres but after fitting the Goodyear Vector 4 Seasons Gen-3 tyres the performance in snow is night and day, no sliding, very little loss of traction and braking distance is vastly reduced. These tyres are fantastic, it's too soon to comment on wear rate which will possibly play a factor in if I purchase again but so far so good. I would highly recommend them too anyone.
