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.

These tyres are good value and perform safely and well when used within legal parameters on UK roads. One slight negative is road surfaces can sometimes make tyre noise quite high but other than that I will definitely buy them again.
12.09.2024 from Michael
The tyres were 7/10 when I got them, the wet straight line grip is great the dry performance is above average. Quiet and comfortable tyres. The tyre wear is poor, I had new arms,tie rods, drop links and bushings as well as alignment done afterwards. The tyres showed excessive wear on the edge after only 8000 miles. I always check tyre pressure every week.

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
02.11.2024 from A Pritchard
Great.
13.04.2024 from Geof Wassell
Driving within my own ability and the ability of the vehicle I choose to drive is what I do. The tyres on my car are part of the interface between driver and road. I prefer to drive with the tyres fully inflated in order to feel the feedback from the surface of the road through noise, suspension and steering, I ballance throttle and brake response with weather conditions, road conditions and temperature. Tyres with less grip just dictate that I should moderate speed and braking at an increased rate. Noisey tyres provide slightly better feedback than silent tyres. The road with current traffic congestion burden isnt the place for performance spirited driving but is the place where defensive driving must be used. I would describe my tyres as competent.

Tyres had side sway when changing lanes. 1st blowout on 20000 2nd blowout on 30000 and at 40000 last remaining Tyres has wall cracks in inside walls of rear Tyres. Definitely a tyre manufacturer problem. Dealer and supplier is saying I overloaded the tyre and drove on flat tyres. The remaining two tyres are available for evaluation.

The tires are much more supple than the OEM Bridgestone Ecopias. Ride is much improved. Wear seems better. Ecopias have little tread depth. No discernible change in economy. A great tyre and at about half the price. Have already bought another set for the future in case Dunlops become in short supply!

11.03.2019 from Philip J C Clements
I have been driving since May 1964 in UK and on the Continent and New Zealand. I consider myself a considerate road user, conscious of other vehicles and their placement on the road. I try to drive as safely and frugally as possible, although I do let my hair down (if I had enough!) when driving my MGTF135 Sports Car on clear roads. I will use the Volvo's power and acceleration when it is necessary to do so, so reducing any exposure to danger- but that does reduce the mpg factor! I have used Bravuris tyres since I bought the car in 2014 and found them excellent value for money.
12.02.2019 from Lewin
Comfortable, stressless.
