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.

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.
12.09.2024fromMichael
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.

Though I'd give these Davanti tyres a go as I've seen a few Davanti dealers popping up all over the place. These tyres are reasonably good in snow and ice but the rest of the year it "feels" like you're driving on snow and ice. Very wayward and "loose" feel to them and a horrible bounce over 50mph like they aren't round anymore, not a wheel balance wobble but a up and down bounce which is very tiresome on longer journeys. There's a noticeable hum from the tyres like old fashioned aggressive winter tyres which changes pitch depending on angle of steering. I am a loyal supporter of winter tyres but these are like torture and not worth the grief in my opinion.

The car was supplied to me with brand new Triangle tyres - a brand I had not heard of and was not one I would have gone for but in the year that I have had them on the car, I have no complaint about their performance. I cannot say whether they would be the tyre of choice when replacement is necessary. t

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 "wobly" effect above 120km..Im not recomend for high speed..But for snow and rain im very satisfied...

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'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.
30.05.2022fromDavid 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’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'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!
