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.

Excellent driving experience on these tyres. They feel safe, sturdy and solid on the road in heat, heavy rain, slippery roads due to mud, country roads, uneven and good surfaces, I have not yet tried in snow or ice. To any walkers reading this, they feel like vibram soles for my car!
07.08.2024 from peter andrews
tyres only have well below normal 6.5mm tread from new and mine were worn down to 4.1 mm tread after 400 miles plus one developed a bulge. Worst tyres ever only have perhaps 1 years life

These tyres are good for grip and average for comfort, but let down on noise levels.

15.08.2025 from Donald
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.
12.09.2024 from Michael
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.

09.02.2023 from Roy Durgan
Very quiet tyres, very smooth comfort.
20.04.2022 from Irving Stewart
The MX5 Mk3 NC is generally regarded by enthusiasts as the worst handling of all the MX5&#39;s due to its extra height, weight, and suspension settings but I deliberately selected this particular version for its comfort, power folding roof, and pleasant ride. When first purchased the car was fitted with ridiculously wide [10&quot;] rims shod with obscure American tyres. It handled like a pig, followed every white line, and a matchstick on the road felt like a small boulder. Fortunately I swapped the big wheels, with another enthusiast, and acquired a set of 16&quot; Momo alloys. These wheels were shod with Falken tyres, two of which were almost new and two almost shot. The decision was whether to change tyre brand completely or see how the Falkens fared. The various MX5 Forums showed a wide range of differing views on the best tyres for my MX5, at hugely differing costs, so I decided as an experiment to stick with the with Falkens and subsequently fitted a new pair to the front. At this stage I should add that it has taken me three years to rebuild this MX5, it is probably my last car, and it is very rarely driven to its limits. Whilst I still enjoy a spirited drive around the enticing Welsh and Shropshire roads, and the occasional run to Essex and the South Coast, I gave up thrashing my cars when I retired from the circuits over 50 years ago! Today safety, comfort, and pleasure are my prioroties! Over three years the Falkens have performed well for &quot;budget&quot; tyres. In the dry they behave well, are quiet, and very predictable. In the wet they can be induced to loose grip [especially on the rear] but I have never had the front break away unexpectedly or in a dangerous manner. An over enthusiastic right foot will induce wheelspin when pulling away in the wet, even in town, but the Falkens soon regain traction. In the dry the rear can be induced to &quot;hang out&quot; but I have never had any major concerns about the car swapping ends. Some of the younger members of the MX5 fraternity have told me that [when run at higher pressure] the Falkens behave well on the track but wear quite quickly which is something I have not tried, and will not experience. Compared to the exhorbitant wear rate of far more expensive &quot;leading&quot; tyre brands experienced by my friends [some as low as 12,500miles per set] on far more recent premium cars, I am more than satisfield with the Fakens and will probably, eventually, replace them with the same brand.
02.03.2022 from Fi Hoang
Great tyres at a good price. Well Recommended.
05.01.2021 from John
Very happy with the tyres - excellent grip in wet or dry conditions. Also wearing well and reasonably quiet.
