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.

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.

These are as close to perfect summer tyres that I have come across in more than 50+ years of spirited driving. Wet grip is of great importance, and these tyres are actually AO, which I always purchase, as I understand that grip was paramount in AUDIs requirements. The car is a modified 25th Anniversary model and is fitted with SACHS Race Engineering Coil-Over suspension. The cylinder head has been ported and polished with the motor now producing well over 200 ps.

Car had 20&quot; 245/35r20 runflats in front and 275/30r20 runflats (all MOE) for RWD w213 luxury saloon. The car came with these factory fitted MOE runflat tyres. I&#39;ve Replaced these tyres and wheels at 10600km. I&#39;ve driven 8600km of that mileage. The tyres wore like rubber bands on the 20&quot; wheels. Steering as a result is very precise in both wet and dry. Front 245/30s have sound deadening foam and overall tyre noise is quiet in the cabin (but just wee bit louder than the 18&quot; PS4 tyres I replaced them with). Ride comfort is 8/10 on highways due to air suspension. On chip seal, speed humps, potholed roads ride comfort is 5/10 - there is very abrupt jarring transmitted to cabin due to tyre profile and rims. Wet grip in cold (5&#39;C) and damp country highways was 7/10 at 110km/h speeds - there was some slip noticeable. Dry grip was 8/10 most of the time but with occasional rear traction slips at highway speeds in curves. This combination of tyres and rims is quite poor for a luxury sedan and compliant rides.

These tyres are great. Low road noise, and surprisingly grippy in the wet. Like really grippy

26.02.2025 from Phillip Claridge
The car was supplied to me with brand new Triangle tyres - a brand I had not heard of and was not one I would have gone for but in the year that I have had them on the car, I have no complaint about their performance. I cannot say whether they would be the tyre of choice when replacement is necessary. t

Gute Reifen, siehe meine Sternebewertung. Warum ich hier schreibe, hat einen anderen Grund. Der Reifen hat EU Label B f&uuml;r N&auml;sseeigenschaften, was bedeutet, dass der Reifen bei N&auml;sse gut ist. Das trifft meiner Meinung nach zu, er ist gut. Gut ist besser als durchschnittlich und logischweise deutlich besser, als schlecht. Es gibt x Tests, die etwas anderes als das EU Label behaupten und sagen, er sei schlecht. Meine Bitte daher, wer auch immer zust&auml;ndig ist: entweder das EU Label ist Unfug, oder die Tests. Beides passt bei diesen Reifen nicht zusammen. Vielleicht fallen sie auch sehr unterschiedlich aus oder passen zu manchen Autos gar nicht. Also nochmal mein pers&ouml;nliches Fazit: ich suchte g&uuml;nstige Reifen mit Berge Label, also offizielle Winterreifen, die bei N&auml;sse gut sind. Meine Wahl fiel auf diese Reifen und sie war richtig. Ich kann die Reifen empfehlen.
02.01.2023 from Ion
I have already 12000 km with this tires and the feeling is very good, even drove with 130 on highway on light rain without any problems, drove on ice roads and it was ok. I gave 4 stars on the show grip because I did not test them yet on show... but overall are very good!

29.05.2022 from Jamie Hewison
Bought these tyres as a bit of an emergency stop gap after somebody had slashed my tyres in a city centre car park, they were only supposed to be on for a few weeks until pay day and I could afford something better, however they&rsquo;ve now been on for 6 months and have been used in all weathers, including a couple of muddy tracks. They perform really quite well, grip is very good in the dry, only a slight decrease on wet roads and better than expected in the snow. Although they&rsquo;re not a mud tyre, they still handled the muddy farm tracks with ease. Fuel economy seems pretty much unchanged, road noise is slightly higher than a premium tyre but not so much that it becomes intrusive. Tyre wear is on par with others, I&rsquo;ve done 10,000 miles so far and judging by the remaining tread, If I run them all the way down to 1.6mm, I think I&rsquo;ll be on course for a 20,000 mile lifespan.
