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.

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’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’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’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’ll be on course for a 20,000 mile lifespan.

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

02.10.2026 from Sue Johnson
Only complaint is I got a black thorn in the side wall within a couple of weeks of them being on the car. Definitely no off road use!!! Tyre not mendable ! Had to buy another. Complained to company but they didn’t refund Very quiet tyres, really pleased with them otherwise
19.11.2021 from Ian Burton-Palmer
These tyres work really well in the wet or the dry road conditions. I also think that they are quite quiet compared the previous set of tyres I had on this vehicle. All round these are a great choice.
02.06.2021 from John Williams
A decent budget priced winter tyre. Very impressed with the grip quality in snow
