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.

29.09.2019 from Lukasz Galanty
First time use Maxxis tyres, has worn on front wheels. Can&rsquo;t believe that tyres from budget class, for me a lot better than previous Uniroyal Rainsport 3. Quality to price, definitely recommended, probably will use again.
01.02.2019 from Richard
These tyres are quiet and grip well in the dry. They also brake well in the wet too and have good aquaplaning resistance. Fuel economy is fine too. However, on a wet road when going around a roundabout at anything over 25mph they loose lateral grip and the car slides sideways. If you push on the power then they completely break off and the car understeers. I am used to it now and drive gently but could be a bit dangerous for those who aren&#39;t experienced drivers. Also on cold damp roads they lose traction at low speeds when turning full lock in a manouvere, sending the ESP system off. I am disappointed because of this and won&#39;t buy again or recommend.
26.01.2019 from Alan
The worst fault i have found with these tyres are cornering. Even at relatively slow speed the vehicle slides, giving up grip rather easy. They remind me of a set of Falcons a purchased a few year back. Not good. Apart from that, an all round decent cheap tyre. Previous tyre i had on Accord were Michelon. A hard act to follow but at &pound;185 a corner !!!!
09.12.2018 from Cristian
Good quality.. did a few burnouts as well and they look just like new :)

I have never triggered the ABS in 8 years of using this tyre, except when testing the surface, and have always felt confident even on wet ice! Great tyre, summer and winter.

Great tyres, safe and give confidence on all surfaces and conditions
13.06.2025 from stevi
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
02.11.2024 from A Pritchard
Great.
13.04.2024 from Geof 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.

17.03.2024 from Mr. 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.
01.06.2023 from Richard Chappell
I was not sure about purchasing these tyres at 1st, but I&#39;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.
10.05.2023 from Andy
Low noise (quieter than the continentals the car had as standard). Good grip all weather tyre. Had several Winguard sports before. Recommended.
19.04.2021 from Alan Bunting
Excellent tyres highly recommend

26.06.2026 from Paul
Bought the Extra Load version. Very happy, lots of grip in the wet , cold and heavy rain. TTS is a firm ride but even these extra load are so compliant, quiet and very comfortable for winter tyres. Had no snow so can&rsquo;t comment on that aspect. Run Goodyear and Vredestein winters in the past but prefer the Yokohamas . Already had set of 17 rims from previous TT which is why I bought 17s rather than 18s. Excellent tyres !
20.02.2025 from Parvaes
Excellent rear wheel drive traction in snow and wet roads
11.04.2023 from Nick Turner
I bought these tyres because of the price and performance and there isn&#39;t much choice for winter tyres on 21&quot; rims. I drive sensibly with a mixture of counrty roads and highways. I have noticed the tyres are quite a bit noisier than summer tyres but that&#39;s to be expected given the tread pattern. Fuel consumption isn&#39;t that different which I&#39;m pleased about. Grip, both wet and dry is exceptional. I usually buy tyres with rim protection, these don&#39;t have it and I have kerbed my wheels, just have to be more careful in future. Overall I&#39;m pleased with these Yokohama&#39;s and would buy again.
22.10.2021 from John Walker
This vehicle is used for both medium distance trips and a considerable amount of off-road mileage through the winter months (September-February). My two previous MLs had been fitted with General Grabber which had performed very well and particularly off-road in wet and muddy conditions, with a tread pattern that did not clog reducing their efficiency and the vehicles had never become stuck. Collectively, these vehicles had covered more than 421,000 miles without issue. However, my newest ML has bigger wheel rims and General Grabber do not build a tyre to fit. Yokohama appeared to be the only manufacturer to build tyres that fitted with anything like a proper off-road tread. My early experiences suggest that they are less efficient off-road than my previous selection, but this assessment is still work in progress.

I purchased the tyres from eyretyres.com and when they arrived they were deformed, totally unusable from a safety aspect. That was over a month ago and i have not received a refund or replacement. Eyretyres are blaming the manufacturer
