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.

Nice Budget tyres with that wide and quattro drive its hard to say it lose a grip or brake bad.
02.05.2022fromAlan
Just put these on the rear of my car. The were fitted on a wet day when the roads were greasy. With the tyres being brand new I was expecting wheel spin when I put the foot down. Nope, not a bit, the tyres bit hard. Even on the motorway at 120 kph when I put the foot down I could feel the extra grip and push which added to the driving pleasure and thrill. I've tried spinning the rear wheels in the wet but they just seem to grip really well.

Handling it depends from road quality, but never excellent. Steering feeling is good. Breaking on dry roads insufficient, ABS function even in middle breaking situations. Very low noise,

04.09.2024fromKP
Performed well in regarded to grip levels both wet and dry, did aquaplane more than the Pirelli’s P zeros but absolutely unbearable road noise and harshness. Yes I had 22” wheels with a very low profile but when compared to the OEM Pirelli P Zero & Scopions I’d avoid these if you want to enjoy your drive.
01.06.2022fromIan
Superb grip on twisty country roads I've had minor spin when pulling away on wet surfaces, but have driven through very wet conditions with no concerns. Noise is more from poor road surfaces than the tyres and they're very quiet on quality roads. Still surprised by how little they've worn in 6 months.
05.09.2020fromElaine barclay
Changed to these tyre as wasnt happy with the grip on the ones I had. Would definitely recommend great grip in wet and dry very good braking and comfortable and not any louder then any other tyre I have had.
