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.

17.03.2024 from Mr. Terry Brown
When I purchased my vehicle (preowned) it came with Nexen tyres on all four corners. I had to change the two front tyres after a few years and choose Goodyears. Last year I had to change the front tyres again because the Goodyears had worn considerably, whilst still having the same Nexens on the rear of the car since I purchased it. Hence stick with the Nexens. When I need to change the rear tyres I will definitely choose Nexens.
01.06.2023 from Richard Chappell
I was not sure about purchasing these tyres at 1st, but I&#39;m pleased I gave them a go as they have performed brilliantly, Even tyre wear all the way around, kept good shape and performed very well.
10.05.2023 from Andy
Low noise (quieter than the continentals the car had as standard). Good grip all weather tyre. Had several Winguard sports before. Recommended.
19.04.2021 from Alan Bunting
Excellent tyres highly recommend

08.10.2023 from David Davies
Hold the road well, good braking in wet or dry, good wear, quiet tyre, reasonably priced.
08.01.2023 from Karl
These are a great tyre at a decent price point, and although the price has been creeping up, I would buy them again. The wet weather handling is especially good and gives real confidence in heavy rain.
10.11.2022 from Will Allen
Very confidence inspiring tyre sadly all four tyres started cracking badly at the base of the tread grove after only two years. I rated Avon tyres very highly in the past but I would never buy the brand again.
24.03.2020 from Ricky
Was warned against this make and model by a friend in kwik fit who said the tyres perish and crack along the tread and I&rsquo;m aft he was right. I only ignored his advice because they were cheap.

Well,im suprised about the drivind experience with those tyres...For me there are a very soft snow tyre... With a lot of gaps to repell the snow..In dry conditions you feel a little &quot;wobly&quot; effect above 120km..Im not recomend for high speed..But for snow and rain im very satisfied...

09.11.2025 from Neil McTear
Far better grip than the Falkens that came with the car, although they still had lots of tread left, they were old and on removal it was found the sidewalls and beads were perished, and were the wrong size. Toyo are current the only manufacturer producing 205/45-15&#39;s and these had previously been unavailable for the previous decade, the improvement in both grip and roadholding is impressive, can&#39;t comment on wear yet due to limited mileage, fuel consumption difference - I haven&#39;t checked.
30.05.2022 from David Hardiman
Huge difference with the new Toyo Tires compared to the older ones I had on the car. These are the best tires I have ever used.
09.12.2019 from Sebastian Dysarski
Good tire soft side wall so corners are average. But overall good price was okay wouldn&rsquo;t pay more
14.11.2019 from Joe
I drive an SW20 MR2 on (almost) original tyre sizes (Rear 225/50/15 and Front 205/50/15), so my choice is limited. For over a decade I&#39;ve used the original Proxes as they were pretty good all-rounders and good value. The new version are very good in the dry - communicative and grippy, you can feel the back end start to let go and everything is progressive and fun. However, the tread pattern gives me zero confidence in the wet as the pattern is in a v direction on one side of the car and a ^ direction on the other. Not a mistake, the &quot;Outside&quot; markings insist this way round. This has to have a huge impact on clearing standing water as the tread is reversed on one side of the car, so I have zero confidence in the wet as each side of the car will behave differently. Bring back the old style that were ^ all round please!

01.11.2021 from Jeremy Nicholls
This is the Volvo recommended tyre on this wheel for this car; generally very happy after Goodyear&rsquo;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&rsquo;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.

I have front set of 2 tires 1 year and around 20000km old, and rear set 6 months and around 10000km. Tyres are excellent for my car on dry and wet. There&#39;s not much snow in this part of England, but was some WET snow last winter and tyres were good on start and in curves but on braking just slide (wet snow i suppose). I have been on the road trip this summer 5000km+, and tyres aren&#39;t worn at all. Good grip in curves on motorway at high speed (up to 180 km/h) on dry and wet.
