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.

This is the second set of the same tyres, and yes they hold the road well. When you have 20 something inch of rubber on the road they can really hold there own. The Which magazine holds Bridgestone to high esteem.
13.10.2020fromBowber
Great tyres, good grip especially in wet, feel safe! Noise isn’t too crazy, hopefully get some decent mileage out of them
11.07.2020fromPat
Much better in the wet than Dunlop tyres that were on the car.

OEM tyre for car. Provide amazing grip in a 4 wheel drive lightweight sports car. Cornering at speed is amazing, braking too.

Excellent in the wet, no hydroplaning or wheeljerk when driving into puddles at speed. This is my second set of this tyre for this reason.
05.10.2021fromMelih PAZI
I'm sorry to say that the tires don't hold up. They always tend to slip.
18.08.2021fromThomas
- I fitted the new Bridgestone Potenza Sport tyres mid April and with very low mileage on the road and less than 100 miles on track the tyres are done and worn out.. - fabrics showing…?! I did many track days previously with the S001 RFTs with no issues- Potenza Sport is simply not a tyre for track use - even for a lap or two…
26.10.2019fromSteve Summerbee
I had no issues with the tyres, which replaced previous Bridgestones.

Steering and wet road handling improved since replacing the standard tyre fitment.
21.05.2019fromJane
I bought these as they rated well performing across the board. Not top in anything but above everything that was top in at least one area. The wet grip and braking is fantastic. Performed well throughout the cold months but we had no snow this year to test them. On warm dry roads the compound or pattern does not allow for an aggressive driving style but I never intended to keep them on in the summer so this was irrelevant to me. They make a noise like driving through standing water in the wet which is strange at first but I wouldn't say generally they were any noisier than my Eagle asymmetric 2 that they replaced. Did everything I expected from them and will be re fitting them come the winter.

These are superb winter tyres which perform exceptionally well in snow and ice. I did my research before purchasing them and would highly recommend them.

2 days in a blinding snowstorm proved their worth. Winter motoring at its best, & extra safety to go with it.

18.09.2022fromDAVID
These are as close to perfect summer tyres that I have come across in more than 50+ years of spirited driving. Wet grip is of great importance, and these tyres are actually AO, which I always purchase, as I understand that grip was paramount in AUDIs requirements. The car is a modified 25th Anniversary model and is fitted with SACHS Race Engineering Coil-Over suspension. The cylinder head has been ported and polished with the motor now producing well over 200 ps.
14.06.2021fromy2kdisease
Car had 20" 245/35r20 runflats in front and 275/30r20 runflats (all MOE) for RWD w213 luxury saloon. The car came with these factory fitted MOE runflat tyres. I've Replaced these tyres and wheels at 10600km. I've driven 8600km of that mileage. The tyres wore like rubber bands on the 20" wheels. Steering as a result is very precise in both wet and dry. Front 245/30s have sound deadening foam and overall tyre noise is quiet in the cabin (but just wee bit louder than the 18" PS4 tyres I replaced them with). Ride comfort is 8/10 on highways due to air suspension. On chip seal, speed humps, potholed roads ride comfort is 5/10 - there is very abrupt jarring transmitted to cabin due to tyre profile and rims. Wet grip in cold (5'C) and damp country highways was 7/10 at 110km/h speeds - there was some slip noticeable. Dry grip was 8/10 most of the time but with occasional rear traction slips at highway speeds in curves. This combination of tyres and rims is quite poor for a luxury sedan and compliant rides.
06.06.2020fromChris Farnell
These tyres are great. Low road noise, and surprisingly grippy in the wet. Like really grippy

I have used Pirelli P Zeros for about 15 yrs and they are a great tyre

Excellent driving experience on these tyres. They feel safe, sturdy and solid on the road in heat, heavy rain, slippery roads due to mud, country roads, uneven and good surfaces, I have not yet tried in snow or ice. To any walkers reading this, they feel like vibram soles for my car!
07.08.2024frompeter andrews
tyres only have well below normal 6.5mm tread from new and mine were worn down to 4.1 mm tread after 400 miles plus one developed a bulge. Worst tyres ever only have perhaps 1 years life
