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.

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 "step-out" 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.

These are an excellent alternative to the Michelin Alpin A3 which I have historically run. They were cracking before wearing out. I needed something that would stick the power of the vehicle and be controllable. These fit the bill admirably.

Really poor wear. Would not buy again. Was getting near 20k miles on cheaper brands. Expected more from Firestone
21.01.2020 from James
These tyres perform well, they're comfortable and they're quiet, but they're fragile and wear too quickly. They get punctured and damaged really easily and don't last as long as I would expect. I've had two full sets of these tyres but after yet another puncture I'm sick of constantly having to change them so I've had them all replaced with another brand. I won't buy these again and I don't recommend them.

Very good Tyre, low noise, very good in the wet.

This was the second time I have purchased this set of winter tyres. Winter 2023 I drove across Czech republic where a heavy snowfall suprised us on the way. With those tyres absolutely no problem, felt safe.
26.04.2024 from Hamish Reid
Able drive through dry snow >15cm and on incline. Had one drive on wet snow that was up to 15cm in depth which only had minor slipping.
09.05.2022 from Eamon Quirke
All good 👍
12.01.2022 from Lee cook
Tyres have performed well so far it's still early January so haven't been able to test their performance in the snow yet but they feel reasuring in the wet the car needed tyres when we brought it so a wear comparison will be difficult but I expect then to wear quicker than standard tyres as the compound is bound to be softer on a winter tyre

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.

Great tyres, good grip, excellent wear property, slightly noisy on road, excellent value for money 👍👍

Great tyre and value for money Amazing grip and breaking in any conditions. I'm aggressive and active driver with 205 BHP, and tyre never failed me. Recommended to all.
21.08.2019 from Rob
Terrible grip in dry and wet. They are dangerous due to the amount drift. I thought they were low on pressure when I first used them. Only fitted to the rear and cause back end to drift when corning at speed. I have no confidence in cornering with them. They are okay in the snow though so if you're using only in snow they should be okay.

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
03.12.2023 from Mustafa
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.
03.12.2021 from Doogride
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!
23.04.2020 from Richard
Fine in most conditions though slightly more wallow. Excellent grip on icy roads truly amazing grip in snow!

05.02.2025 from Naveed Anwar
It slips on roundabout, and slipped in snow and wet. I would never buy this tyre. It was a mistake.
16.01.2022 from Adam h
Very bad grip on wet roads, car keeps understeering even going at low speeds. Will not buy again.
04.07.2020 from Stewart Dalzell
Only had these on 2 days but seem very very good considering the price point, on greasy wet summer roads etc, the are very linear and let you know when they are going to lose grip although seem very grippy considering the C wet rating, with a finger nail to the rubber it is quite soft therefore I don't expect a lot of mileage out them. I only use the van as a basic camper or for mountain biking, so we'll see what the winter performance is like and once there is more wear on there. In conclusion, if you need a cheap quick fix for an all season tyre that won't lead you into a ditch straight away then I'd say give them a go. :)
