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.

Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

Very good Nordic winter tyre, the best on ice there is.
22.04.2021 from Jon
Best winter tyres I've had. Great grip in the snow and really good on cold roads and in the rain. Have performed well now that it's started warming up. Size (not listed on the Dropbox) 245/40/18

Good grip, solid performance on rough country roads, and smooth enough on A roads, balanced breaking and no vehicle shudder
05.02.2025 from Dean
I've done around 8500 miles so far in mostly poor weather , very good grip in all winter conditions and mild conditions. Good all rounder.
28.05.2024 from Marcis
Good grip on wet and dry roads. Reasonable grip on snow and icy roads. Noisy on dry roads. Fuel consumption has increased. All in all decent tyres.
07.04.2024 from Harry
Incredibly capable tyre for all conditions, but my experience on the roads in West Yorkshire will probably dictate that I don't purchase these tyres again as they are too soft on the sidewall, they do need some sort of protective band. The roads a terrible around Haworth for potholes, and in this case I could not dodge one and it has ripped the sidewall and damaged the rim, rendering the tyre scrap.

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's and these had previously been unavailable for the previous decade, the improvement in both grip and roadholding is impressive, can't comment on wear yet due to limited mileage, fuel consumption difference - I haven'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’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'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 "Outside" 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!

One of the best winter tyres I had from year 2007, when I started to drive my own car. Confident driving also with one side on ice, another on dry surface, on wet snow or just wet surface.

06.09.2025 from Zoran
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'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't worn at all. Good grip in curves on motorway at high speed (up to 180 km/h) on dry and wet.

04.09.2024 from KP
Performed well in regarded to grip levels both wet and dry, did aquaplane more than the Pirelli’s P zeros but absolutely unbearable road noise and harshness. Yes I had 22” wheels with a very low profile but when compared to the OEM Pirelli P Zero & Scopions I’d avoid these if you want to enjoy your drive.
01.06.2022 from Ian
Superb grip on twisty country roads I've had minor spin when pulling away on wet surfaces, but have driven through very wet conditions with no concerns. Noise is more from poor road surfaces than the tyres and they're very quiet on quality roads. Still surprised by how little they've worn in 6 months.
05.09.2020 from Elaine barclay
Changed to these tyre as wasnt happy with the grip on the ones I had. Would definitely recommend great grip in wet and dry very good braking and comfortable and not any louder then any other tyre I have had.
