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.

04.04.2021 from Marco L.
Piacevolmente impressionato, gomme silenziose, consumi bassi e ottimo grip. Per una guida 80% extraurbana e 20% cittadina con andatura tranquilla sono veramente ottime. Magari le crossclimate della Michelin saranno più performanti, ma a questo prezzo è difficile trovare di meglio.
27.10.2019 from Craig McQueen
Sticks well to the road on corners in all conditions at all speeds. Gives confidence. Tyre is 225/40 R18. Not size available in drop down menu here. Built in kerb protection is welcome on such low profile tyres. Good value tyres, have used this brand for years over about 500,000miles with no issues, lasting 30000 miles plus on drive axles and had 66000miles on trailing rear axle pair!

So far so good, no snow to test so far, but in wet good... And in dry good,... Not sure of the wear yet but I've noticed fuel consumption is very economical and the tyres are very very quiet, not as loud as the old rumbling Bridgestones, £ 50 x 4 tyres kwik fit 👌👍

Not bad performance at low price.If you are looking for cheap tires with good grip on wet roads Leao Nova-Force will be a good choice

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.

11.06.2021 from Shaun Thorpe
Damn right dangerous... had these put on less than 6 months ago, and if you drive in a slightly spirited manner the lack of grip is phenomenal. 30mph bends leave you requiring replacement underwear. And it just gets worse in the wet. Braking distances are terrible in both wet and dry, but they are comfy for 45's. These are a drift tyre in my opinion, cheap and grip less. I only have 150bhp apread across all four wheels and they still slide, I wouldn't recommend them on anything with more than 100 ponies. And if its slightly moist or greasy out, you better be good at throttle control and counter steering... at low speeds they are perfectly acceptable, but if you like to put your foot down abit I'd spend some more money, we don't scrimp on safety.

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!
