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.
 
x
Original equipment quality: optimum adjustment to the vehicle
Tyres with a special OEM marking on the sidewall, e.g. "MO" for Mercedes-Benz, were developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been homologated by the vehicle manufacturer and are a perfect match for a specific model. They have been specially designed to highlight or further improve the performance characteristics of the car in question, thus representing the culmination of a state-of-the-art fine-tuning process that perfectly complements the latest technological developments in the automotive industry. Tyres with manufacturer's markings can of course also be used on other vehicles.

The tyres lasted about 3 weeks before one had a blow out the side wall of the tyre went on a motorway nearly caused an accident we were towed to a fast fit centre so they fitted 2 new tyres to replace the ones from mytyres I tried contacting the supplier had no answer from my email and the phone put on to a very unhelpful gentleman who took no notice of any thing I said. So I would say DON’T buy tyres on line go to a fast fit that way if something goes wrong you can claim.

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.

Good tyres but not as good as the Michelin pilot sport 4. Will be going back to the sports.
04.12.2019fromAli
I am a High mileage driver covering all roads day and night. This is a premium summer tyre made for dry grip and wet braking. Out of a budget , midrange and premium I’ve noted , the cheapest gives me around 6000 miles. The mid ranges cover around 12000 miles and premiums last around 18000 miles. In terms of grip it always has to be premium. These are also much quieter than budget tyres. I’ve covered 25000 miles of hard driving with these tyres and they still have around 3mm left. This is the second summer I’ve purchased these tyres. Good on price as well as grip

Great tyres, safe and give confidence on all surfaces and conditions
13.06.2025fromstevi
best tyres ever had them on Audi A3 TDI sport ,fiesta st .ford focus MK2,jaguar xj 3Ltdi best grip ever handles in wet like a great tyre does when dry grips so hard in the dry the engine struggles to go faster because of the grip tried all the named brands like Mitchellen ,toyos ,co rentals and the uni royals beat them ever time not just price but grip safety and handling too .never use any other tyre the 5s are better than the 3s but not by much . hard to improve on such a great tyre
02.11.2024fromA Pritchard
Great.
13.04.2024fromGeof Wassell
Driving within my own ability and the ability of the vehicle I choose to drive is what I do. The tyres on my car are part of the interface between driver and road. I prefer to drive with the tyres fully inflated in order to feel the feedback from the surface of the road through noise, suspension and steering, I ballance throttle and brake response with weather conditions, road conditions and temperature. Tyres with less grip just dictate that I should moderate speed and braking at an increased rate. Noisey tyres provide slightly better feedback than silent tyres. The road with current traffic congestion burden isnt the place for performance spirited driving but is the place where defensive driving must be used. I would describe my tyres as competent.

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.

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!

17.03.2024fromMr. Terry Brown
When I purchased my vehicle (preowned) it came with Nexen tyres on all four corners. I had to change the two front tyres after a few years and choose Goodyears. Last year I had to change the front tyres again because the Goodyears had worn considerably, whilst still having the same Nexens on the rear of the car since I purchased it. Hence stick with the Nexens. When I need to change the rear tyres I will definitely choose Nexens.
01.06.2023fromRichard Chappell
I was not sure about purchasing these tyres at 1st, but I'm pleased I gave them a go as they have performed brilliantly, Even tyre wear all the way around, kept good shape and performed very well.
10.05.2023fromAndy
Low noise (quieter than the continentals the car had as standard). Good grip all weather tyre. Had several Winguard sports before. Recommended.

I bought these tyres as wanted a budget sport tyre for our recently purchased vauxhall Insignia, so got a pair from Oponeo. They sent Sport 2's which are a Chinese made model. Have been generally happy with these as been on some long & many short trips in last year. They have given confidence inspiring performance through all weathers & never given me reason to regret buying them. They wear well too as still lots of tread left. Recommended...
23.08.2022fromCallam
Good grip on a dry warm day , Starts excessive oversteer in the wet, and they are almost down to the treadwear indicator in just under 3 k miles . Easily looses traction under acceleration in the wet
