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.
 
x
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.

After using Michelin tires for the past 20 years model PS4, ENGERY SAVER, the cross climates on this vito crew sport, the tire life has being shocking, 8,000 miles and there so expensive 1k a set, so decided to give the Goodyear&#39;s ago, I&#39;m was shocked at how well these are performing, the ride is so much better, the Michelins have straight side walls, which ride very hard, you feel every bump..... Goodyear&#39;s ride comfort, life and grip has been amazing I&#39;ve done 17,000 miles and there is still life on the rear tires, id say there will do 22,000, and an set of these is 600 quid.... see you later Michelin, all my vans and cars are going Goodyears.....
08.06.2026 from J Amin
This is the second time I have bought a full set of these tyres. I mostly drive on motorways, country roads and off road. My fuel efficiency went up when I put on my first set. The ride is more comfortable and the grip is excellent in dry and wet weather. They have performed well on snow. Despite being all weather the rate of wear is very good. I would definitely buy them again.
18.09.2024 from Ersan
My tyre size was 205 55 16 but not in the list! Unbelieveble in wet surface but average on dry breaking. Good aquaplanning and snow traction. Good comfort but average noise.
06.03.2024 from Viktor
Tires keep the vehicle nicely on the road, no traction problems. On ice British roads they perform great no problems stopping or going.

Only downside to the tyres is cornering tightly , roundabouts in half wet dry conditions slip evident if pushed even a little over normal roundabout speeds . Otherwise a very good tyre in all conditions , wet grip in heavy rain also very good .
10.12.2025 from Stephen Brown
Great tyres, safe and give confidence on all surfaces and conditions
13.06.2025 from stevi
best tyres ever had them on Audi A3 TDI sport ,fiesta st .ford focus MK2,jaguar xj 3Ltdi best grip ever handles in wet like a great tyre does when dry grips so hard in the dry the engine struggles to go faster because of the grip tried all the named brands like Mitchellen ,toyos ,co rentals and the uni royals beat them ever time not just price but grip safety and handling too .never use any other tyre the 5s are better than the 3s but not by much . hard to improve on such a great tyre

These tyres in my rear wheel drive BMW are grippy in the dry, but leave me yearning for more in the wet. The car will &quot;step-out&quot; if I punch it whilst the road is even midly damp. My tracking was done at the same time as having these fitted so that is not a factor. The car will also step out if the road is more greasy looking.

04.04.2021 from Marco L.
Piacevolmente impressionato, gomme silenziose, consumi bassi e ottimo grip. Per una guida 80% extraurbana e 20% cittadina con andatura tranquilla sono veramente ottime. Magari le crossclimate della Michelin saranno pi&ugrave; performanti, ma a questo prezzo &egrave; difficile trovare di meglio.
27.10.2019 from Craig McQueen
Sticks well to the road on corners in all conditions at all speeds. Gives confidence. Tyre is 225/40 R18. Not size available in drop down menu here. Built in kerb protection is welcome on such low profile tyres. Good value tyres, have used this brand for years over about 500,000miles with no issues, lasting 30000 miles plus on drive axles and had 66000miles on trailing rear axle pair!

Had a pair on this jeep previously and they proved very good for the rear axle. For the money the value in longevity and grip in dry conditions is excellent. This is now a second pair for the rear axle and performance is as good as previously.

21.09.2025 from John
I bought these tyres as wanted a budget sport tyre for our recently purchased vauxhall Insignia, so got a pair from Oponeo. They sent Sport 2&#39;s which are a Chinese made model. Have been generally happy with these as been on some long &amp; many short trips in last year. They have given confidence inspiring performance through all weathers &amp; never given me reason to regret buying them. They wear well too as still lots of tread left. Recommended...
23.08.2022 from Callam
Good grip on a dry warm day , Starts excessive oversteer in the wet, and they are almost down to the treadwear indicator in just under 3 k miles . Easily looses traction under acceleration in the wet

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
