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.

OK concerning all aspects - Except NOISE. Really bad ! Not in the topline other Comfort-aspects. But ok. The noise level on the Swedish often very coarse asphalt is horrible-I will have too change tyres. In comparison with the 17&quot; wintertyres -friction- the soundlevel is extremely different-VERY FAR FROM ACCEPTABLE. Strange-when you look att the EU db figures (68 db) , but that must be a value on an extremely smooth Surface. The noisiest tire I ever had !

Bought on the suggestion of the Romanian Dacia Duster Facebook group who do extensive tyre testing on a light(ish) 4x4 akin to the XJ Cherokee so their results deemed comparable. Very impressed with this tyre such that I have ordered another set. After a few thousand miles I had total confidence in the tyre and even happliy drove in RWD only due to the progressive nature of the AT3 Sport2. Snow performance was a big surprise as this tyre is very capable.

These are an excellent alternative to the Michelin Alpin A3 which I have historically run. They were cracking before wearing out. I needed something that would stick the power of the vehicle and be controllable. These fit the bill admirably.

Tyres perform really well in all conditions but I scuffed 2 of them on the kerb part of the tyre wall just peeled off and left a gap 4cm wide and about 5 cm deep the rim of the tyre seems too soft this part of the tyre provides little or no protection for the alloy wheel . Dissatisfied with this aspect of the tyre. And these are not cheap tyres!

Smooth and comfort
07.05.2019 from Andrew Cole
Since putting these tyres on my SUV ive noticed its handles its self extremely well in the corners at speed . Road noise is a lot less quiter than my previous tyre &quot;Nexen Roadian&quot; Only thing ive marked it down for is in the snow as i have not driven in any snow at all no snow this year . I would definitely buy these tyres again .

Amazing tyres, grip is excellent, comfort and noise are excellent. the only thing i can fault is that the wear isn&#39;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.
10.08.2023 from DanB
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 &pound;250 cheaper than the PS5s; but more or less neck &amp; neck with them in the tyre review! That swung the decision for me, more so with the money saving!

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.
