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.

Steering and wet road handling improved since replacing the standard tyre fitment.
21.05.2019fromJane
I bought these as they rated well performing across the board. Not top in anything but above everything that was top in at least one area. The wet grip and braking is fantastic. Performed well throughout the cold months but we had no snow this year to test them. On warm dry roads the compound or pattern does not allow for an aggressive driving style but I never intended to keep them on in the summer so this was irrelevant to me. They make a noise like driving through standing water in the wet which is strange at first but I wouldn't say generally they were any noisier than my Eagle asymmetric 2 that they replaced. Did everything I expected from them and will be re fitting them come the winter.

I have front set of 2 tires 1 year and around 20000km old, and rear set 6 months and around 10000km. Tyres are excellent for my car on dry and wet. There's not much snow in this part of England, but was some WET snow last winter and tyres were good on start and in curves but on braking just slide (wet snow i suppose). I have been on the road trip this summer 5000km+, and tyres aren't worn at all. Good grip in curves on motorway at high speed (up to 180 km/h) on dry and wet.

14.06.2020fromjohan silkenas
Smooth and absolutely lovely on snow, sensational grip. Great feel of safety on wet roads. Used to drive with Pirelli Sottozero 3 winter-tyres which are great too however these GoodYear UltraGrip Performance + winter-tyres are a new level of tyres.
28.05.2020fromWill
I drive an automatic which is terrible for grip with only the slightest snowfall, and I’m very cautious in sub zero icy weather. However with the UltraGrip Performance + tyres I was full of confidence every time I drove in sub zero weather conditions. Breaking distances were further than summer tyres, as expected, but nothing to worry about. Car performance was very good and fuel consumption while motorway cruising was better than summer tyres! There was no snowfall this year so I cannot comment.

The tires are much more supple than the OEM Bridgestone Ecopias. Ride is much improved. Wear seems better. Ecopias have little tread depth. No discernible change in economy. A great tyre and at about half the price. Have already bought another set for the future in case Dunlops become in short supply!

10.07.2019fromPeter Bergelin
I drive more heavy footed than my wife and I have purchased tyres for £200 + each in the past and they lasted 8 to 10 months. These tyres last around 14months minimum in the front and there are a lot of round about to travel around. They give excellent grip in all weathers.
26.08.2018fromMike
Bought these to replace the OEM Goodyear wranglers as they were avalaible, price and reviews were good, and the Goodyear’s wear wasn’t up to scratch in my opinion. They didn’t transform the handling of the car, but it’s a 7 seat giant of a SUV and so not too sporty in the corners anyway. The grip in both dry and wet wasn’t significantly worse than the Goodyear’s, and probably a little better in all but dry conditions. Had a few days use on snow / ice on treated and untreated roads, and combined with the electric wizardry of the Discovery, seemed to cope a lot better than the 1.8mm Goodyear’s i’d Just taken off. Whether the reed depth made more of an impact than brand i’m Not entirely sure. Seem to be lasting well after 12,000m I certainly would buy them again.
06.09.2015fromMr Paul Hamilton
I was a little worried about purchasing tyres from the internet at first, however mytyre were very professional and delivery was prompt, however I recommend you check your tyres carefully on delivery as one of my tyres was the wrong size, however it was rectified promptly. Although I paid for fitting which usually costs around £10 to £15 a tyre I still saved £180. The tyres were deliverd packaged and looked great, the EU standard efficiency marking was very helpful in choosing the tyres, I had great tyres and great service from Mytyre.
