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.

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

Car now relegated to daughters using it for general use. Fairly rural roads, with. mixed road surfaces. The XL rating of the tyre & tread pattern is good for going up a farm track to where the pony has stable.

4 tyres fitted to a small Kangoo van. They perform well for a slow, tough little van/car that is used for ferrying building materials and going to and from building sites. I don't drive fast or try to push the van beyond it's limits. For this purpose the tyyes are very adequate.

I thought about trying to get a refund. They make a terrible rumbling noise is one or two psi off optimum. Never had a tyre do that before.

Smooth driving. Lowered noise levels compared to other snow tyres purchased in the past. Good speed rating(driven through Germany on Autobahn) Good grip on wet roads/motorway
03.12.2023fromMustafa
The tire behaves excellent on both dry and wet roads. Especially on snowy/icy roads it does its job really great. It's a truly price/performance tire and would definitely recommend to buyers.
03.12.2021fromDoogride
Noisy piece of crap. Above 110km/h changes your vehicle into vibrating boat you cannot steer safely on highway. First and last Goodride (Westlake) that I ever purchased. Avoid that chinese garbage!
23.04.2020fromRichard
Fine in most conditions though slightly more wallow. Excellent grip on icy roads truly amazing grip in snow!
