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.
02.05.2022 from Alan
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&#39;ve tried spinning the rear wheels in the wet but they just seem to grip really well.

31.03.2021 from Alan Foster
I bought these tyres because I do occasional track days. If I drive hard on a track day the outer edge of my front tyres are heavily worn. I wanted a tyre that would withstand a track day, but still be good for everyday use. This tryre is perfect for this. Not outer edge issues at all on track day and plenty of grip in wet winter on normal roads. My fuel consumption has increased a lot. I do not know if this is the tyres (only fitted on front) or because I am doing shorter trips due to lock down.
16.08.2018 from Ollie
For a summer tyre, these are great in the wet, adimitadly there&#39;s still plenty of tread left so this could be part of this. A lot of people said these were no good in the wet, that&#39;s rubbish. Damp or wet roads these still have better levels of grip than a normal road tyre, they just don&#39;t handle standing water very well (As would be expected this this type of tyre). As long as you drive to the conditions you won&#39;t have any issues with rain. I&#39;ve even had 3 days in the snow with these...lets just make it clear these are NOT snow tyres but they done suprisingly well. The only thing I noticed is that you have to warm them up, when cold they seem a bit loose. After a few minutes driving they get to decent levels of grip but you need to drive a bit harder than normal road conditions to get them to full potential. It would have been nice if they were still available in this size with the softer compound. They are on the latest MSA list 1B though so don&#39;t get caught out - some of the smaller events like the autosolos won&#39;t allow you to run with them. The side walls are stiff enough to give some sharp turn in but you trade that off with road noise and a stiffer ride but again that is to be expected. All in all these are great tyres for the price.

I had them on the front from new, after 2000 miles they start generating more noise ,after 10000 miles (1 year) depth tread was 2mm. Never buy any cheap tyres again .
23.02.2025 from Ricardo Rodrigues
Good grip on dry and wet , the noise is not bad but only lasted 10k miles. All uniform wear but only lasted 10k with very smooth driving
25.11.2024 from Liam Denning
I&rsquo;ve tried to push these tyres to the limit and they hold up really well. Great performance overall, doing as well as the premium priced Continentals they replaced. Well impressed!
22.08.2024 from Kevin Broderick
Really good tyres. Bought on the mechanics recommendation and I&rsquo;m delighted I did. Just as good as the Michelins they replaced. Excellent grip on wet roads even at high speed.
