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.

01.11.2021 from Jeremy Nicholls
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.

These Trazano Z107 tyres were initially adequate as budget tyres but over time they have become noisy at speed and wet grip is now atrocious - with 5mm of tread still on the tyre. A regrettable purchase. I will revert to my usual Pirelli Cinturato which performed admirably right down to the tread wear markers. Lesson learned.

21.02.2026 from Alan Marshall
Fabulous tyres and exceptional wear, considering the price point of these, especially given my driving style. I'll definitely see over 20000 miles on these tyres which I find remarkable on a heavy car with over 400hp. Could I have better grip, sure for twice the price. Do you really need it, even for having fun on UK roads, no! They are soft rubber though, so you'll know if your alignment is out, these didn't last long on my Merc V Class!
08.08.2020 from Dean
Doing relatively high mileage of over 40k every year, I've been through various different premium tyres over the years. Let me tell you, in the 5k miles on these tyres so far I'd say they're pound for pound up there with premium tyres for everyday driving. I've found them to be really good in the wet, no major drama with aquaplaning and my heavy right foot has encountered no issues in cornering. Strangely, I've found that I'm more confident with these in the wet than dry- they tend to be slightly unpredictable when pushing on. Not a massive issue by any means and shouldn't put anybody off, it's just highlighted by my spirited driving style! Wear seems to be decent so far, but as I said I've only done 5k so far so too early to tell. All in all, great value for money and worth a try. On 20's, The Goodyear Eagle F1s that I had on previously were £160 each, whereas I got these for £115. 200 quid saved, and genuinely no worse performance. Well done Viking!
18.10.2019 from W Edbury
The car feels very safe cornering and braking is very good , it drives straight no wandering overall I’m very satisfied with the set of Tyres.

Tyres can be noisy over rougher surfaces but seem to be lasting well. Not really had any snow to speak of to test them on properly but perform well enough in very wet conditions on roads. Fuel consumption seems to be slightly worse than with summer tyres fitted but not too noticeable, getting around 35mpg at each fill up - was getting 35 to 38 with previous tyres.

I've already replaced the winter tire for summer tires

29.05.2025 from Jerry
I began using these tires last winter and drove them all over Europe, on both dry and snow-covered roads, including motorways and countryside routes. So far, I have driven approximately 7,000 km on them and have not encountered any issues. They perform reliably on snow, as well as on dry and wet surfaces. The noise level from the tires does not seem to be louder than that of other tires, although this may vary depending on the type of car you drive and its level of quietness. Additionally, the price was reasonable. Therefore, I will definitely consider purchasing these tires again in the future.
22.03.2025 from Marcin
tires never arrived, money back after a month, I do not recommend
09.03.2025 from Marek
The tyres have good performance, of course the UK speed limit of 113km/h does not allow for a better test of the tyres on wet roads.
27.12.2024 from Ian
Tyres seem fine no problems so far. Have not had a chance to test on snow.

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
