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.

Noted an increase in millage from tje start, also noticed a noise reduction while driving. Good grip and reduced roll. All in all a good upgrade for electric cars.
10.06.2021fromAnthony Hibbs
I bought these tyres as they are the only ones on the market that claim to be specifically designed for electric vehicles and are carbon neutral in their manufacture. Lots of claims made by Michelin regarding low noise levels, grip, wear and increased range. I can confirm that the tyres live up to these claims in all respects. I have driven around 1200 miles in mixed road and weather conditions and have been very impressed. My eGolf was always a quiet car, but now it’s almost silent with little or no road noise below 50mph. Braking and handling in wet or dry, good roads or bad, is exceptional. My average range previously was around 150 miles from a full charge, now it’s 160 miles, remarkable. I absolutely recommend these tyres for electric vehicles.

Super quiet, lovely ride comfort, but also perform brilliantly in the wet. Not had a chance to test this set in snow, but a previous set were excellent on packed snow.
17.06.2022fromM Bradley
Side walls made of Cheese clipped a stone on the road, nothing big, ripped the sidewall, and broke the beading wire, Tyre was 3 days old. in 40 plus years of driving ive never had a bead wire break on a tyre, the garage had never seen one either. contacted continental and was ignored. last time i will ever have these tyre or continental on my vechicals.

These tyres are the best I have ever had. They are excellent in wet conditions and perfect in snow

Amazing tyres, grip is excellent, comfort and noise are excellent. the only thing i can fault is that the wear isn't anything special. Down to 4mm after 6000 miles. My tyre size is 245/35R18 but tyretest will not let me add the correct size above.
10.08.2023fromDanB
Excellent tyres chosen via the reviews by Jon @ tyrereviews.co.uk - they faired very well against the likes of the Michelin PS5s and at the time of buying (Feb2023) the Goodyears were £250 cheaper than the PS5s; but more or less neck & neck with them in the tyre review! That swung the decision for me, more so with the money saving!

07.02.2022fromSpiros
Car Driven : BMW 425D 225Hp . Quite quietly from the start until the first 10,000 km they kept a relatively low noise level until the end of their lives. Relatively comfortable especially considering that is a runflat tire. The tire tread still retains its original groove and design but has significant wear points on both edge and there are some small tire detachments. In the few rains we have in Greece it never had a hadling problem or breaking and did not create any feeling of insecurity. in short it is a good quiet tire ROF tire, comfortable and efficient in fast driving.

I drive mostly in the city at low speeds however when taking to motorways in the UK I drive at 70MPH and in Europe at 75MPH. The drive is smooth and fuel economy is excellent, tyre wear is good and noise levels within the car is minimal.

Excellent safe and fun. You need to give warning when it won’t arrive for weeks before the customer pays though. I was stuck without something suitable. It’s not acceptable.

This is an excellent tyre, first class grip in snow and ice and also works very well in the summer, although I believe this is not recommended.
