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.

I have never triggered the ABS in 8 years of using this tyre, except when testing the surface, and have always felt confident even on wet ice! Great tyre, summer and winter.

20.02.2026fromMr 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&#39;s 2014 Audi A3 and our &#39;spare car&#39; a 2009 Fiat Panda 4x4. They are all on all year round and have acceptable wear even in hot summers
06.02.2026fromJim Hutchinson
What makes these tyres stand out is their performance on very wet roads or standing water.
27.02.2025fromMichael 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&#39;t know how to drive in the snow. They are sure footed in frost too.
22.01.2025fromMr 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

Best winter tyres I&#39;ve had. Great grip in the snow and really good on cold roads and in the rain. Have performed well now that it&#39;s started warming up. Size (not listed on the Dropbox) 245/40/18

09.11.2025fromNeil 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.
30.05.2022fromDavid 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.
09.12.2019fromSebastian Dysarski
Good tire soft side wall so corners are average. But overall good price was okay wouldn&rsquo;t pay more
14.11.2019fromJoe
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!

02.12.2020fromRafal
I changed tyres from Conti Premium and I am preete happy with Hankook. It is also a premium tyre.
22.05.2020fromPieter
The biggest problem with these tyres ar that they do not have rip protection. I have been using Hancooks on my previous car, so when looking for tyres for my current car, Hancooks came to mind. I had a better driving experience with the tyres that I replaced.
06.12.2019fromWhite
These tyres give a superb quiet ride. I also have these tyres fitted to the front of my vehicle, which have now completed 45,000 km and the wear is every bit as good as the Michelin tyres they replaced. Although I do not drive in an aggressive manner I have not noticed any detriment in road holding or fuel consumption.
