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.

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.

These tires are Continental Viking 6 clones (compound, sipes, grooves, pattern, literally everything, compare yourself), branded differently and hence cheaper.... Believe me, these are very good! Buying chinese winter tires is like gambling, you never know how they will perform as the reviews are non existant for the specific tire / brand or very few.... but im here to say, these are maybe the best winter tires ive had... they are not as good as Nordic Friction tires (Nokian Hakkapelitta, well, they are the best Winter tires in the world) but just as good and/or better than the rest honestly.... like Nokian WR D4 or Continental Vik. 6.... infact they are like Continental Vik. 6 clones, you would think they are a fake version of them, but nope, they are just that good.... which is very good...

15.08.2025 from Donald
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.

08.03.2025 from Michael Blunt
The tyres perform well for day to day driving, but lack confindence in the intial turn if your pushing the car. The brakng performance in a straight line whiles in wet is incredible and reliable. Accelerating in the wet very good but not as good as the braking. The tyres do not make much noise on the motorway and seem to be puncture resistant. I would not recommend these tyres for those who want to push the their on the weekend as they simply let go.
26.02.2021 from Arek
Good all-round tyres. Safety & quite.
02.04.2020 from Clive Williams
The tyres have provided a remarkable improvement in handling and grip, inspiring confidence that translates into improved A-B times as well as being more comfortable than the previous tyres i.e. Nexen.

20.02.2026 from Mr Neil Richard Parnham
These are a thoroughly dependable tyre and the Expert 2 (and the later Expert 3) are superb tyres. In addition to the stated vehicle I have a set on my wife's 2014 Audi A3 and our 'spare car' a 2009 Fiat Panda 4x4. They are all on all year round and have acceptable wear even in hot summers
06.02.2026 from Jim Hutchinson
What makes these tyres stand out is their performance on very wet roads or standing water.
27.02.2025 from Michael Payne
I am a careful driver. Mostly urban with some motorway driving. The tyres I chose are all season. Whilst I live in Edinburgh City, when snow falls I need to drive 800m and up 2 hills in order to get to a road that is kept clear and often there are cars and a bus strewn across the road. Amazing but true. These tyres have allowed me to bypass these cars and proceed to the swept roadway. 2 times this winter. Scarcely believable that people don't know how to drive in the snow. They are sure footed in frost too.
22.01.2025 from Mr Neil Richard Parnham
We have owned this car for almost 11 years now and the last 9 years have been on firstly Uniroyal MS+77 205/55 R16 91H and then for the last 3 years on AllSeason Expert 2 which is a vastly improved tyre. The latter is so much quieter and returns improved fuel consumption and I believe better grip in wintry conditions

This is the Volvo recommended tyre on this wheel for this car; generally very happy after Goodyear’s on previous non sporting V70s.
01.11.2020 from Stewart Blake LEISHMAN
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.
13.10.2020 from Bowber
Great tyres, good grip especially in wet, feel safe! Noise isn’t too crazy, hopefully get some decent mileage out of them
11.07.2020 from Pat
Much better in the wet than Dunlop tyres that were on the car.

My car is the 90Hp 1.6TDI, CAYB engine and 5 speed transmission. I return on average 65mpg with these Fulda winter tyres on - no drop off from the summers [they were not good summers that came off it]. I drive on UK A and B roads in Shropshire, Herefordshire which are very agricultural with lots of pot holes. I killed a Fulda front tyre in 100 miles as I missed a huge pot hole at night at 50mph, the tyre did not burst but it egged - luckily I bought 6 tyres expecting a problem as the roads are horrendous and the tyres 40 series so too low profile for where I live. I drive to purposely avoid pot holes, but still catch them - the tyres and rims have survived unscathed since. I suspect they are slightly noisier than the summer but only on some road surfaces. Grip is very good in wet and predictable in the dry - not an ultimate grip tyre BUT here is my point, it appears to me on a very low power and lightweight car [1,200kg] to provide very consistent grip regardless of road surface which is what I want. Great grip in wet mud and standing water also. I would recommend for a good general tyre. I've done about 5,000 miles on them so far and wear even at 10degC is fine.
19.09.2021 from Allan Fulton
Excellent in wet superb handling and breaking
05.09.2019 from Peter
Although a "Winter" tyre they are a good all rounder mud & snow. Tyre wear is obviously not as good "summer" tyres and other tyres may be better for high speed autoroute driving.
