Summer tyres - optimal grip guaranteed!
On dry roads or mild weather, your tyres have to face some increased demands and must always meet safety standards. Compared to winter tyres, the rubber mixture of the summer tyres is harder, even in high temperatures. Default rolling resistance and wear are smaller, resulting in a greater lifespan, comfort and increased stability. Choose now from our offer your summer tyres at an affordable price. Our portfolio includes a wide range of tyre brands
 
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.

A good value tyre, fit and forget - unremarkable but not in a bad way. They&#39;re only vice is they&#39;re not terribly puncture resistant and one has had to be replaced rather than repaired

On my second set of these tyres, excellent grip and handling. Good in the wet too

I replaced the original MG4 Continental tyres with these Yokohamas after about 20,000 miles. These new tyres have so much better grip in all weathers. These new ones are however a little less comfortable on UK road surfaces (which causes more road noise) as the Continentals were really comfortable with little road noise.
06.10.2023fromVictor
On wet roads, the cornering capability is reduced compared to Bridgestones, however these tyres cost 30% less. All in all, for mixed driving, it&rsquo;s a great all rounder, especially since it&rsquo;s very reasonably priced. A decent everyday tyre. We&rsquo;ll see how long it lasts, but seems promising, so far. Noise level is quite low too.

My size tire was not available on the site, it&#39;s 21&quot; and not 18&quot;. My experience is maybe unique to Tesla cars, but it has only 1-2mm left after 17000 km. With Hankook and Pirelli, I&#39;ve gotten better milage... The tire can suddenly lose grip in aqua planing conditions, which I did experience once on the highway - and not with any other tire. But maybe all tires would have this issue under the same conditions. My main issue is that the tire wears our very quickly especially on the rim area, making tires wear out prematurely and they easily puncture if not detected (can see white threads, but not visible easily if on the inner rim). Some of this is likely due to Tesla ABS system activating easily in sharp curves, as I have not experienced these issues with other car brands. Both model 3 and model S have this issue. These tires I need to replace quicker than 17000 km as one of tires has just approx 1mm thread.

I chose the Pilot Sport 5s for my car for 6000 miles of arduous driving, leading a classic car rally around all of Greece. We were heavily laden and driving hard on very mixed surfaces. The Pilot Sports never let us down and showed impressive grip throughout. Even better, 10,000km later they have worn remarkably little, and very evenly. The sister car was on Toyos which admittedly are cheaper, but showed a LOT more wear.
22.08.2022fromJustin
Size = 255/40/19. I had the Pilot sport 4 on the front, went for the PS5 on the back as they were just available and they were great. I would definitely go for them again but I just changed my car and it looks like Michelin do not support the new size tyres (305/30/ZR21) but I will keep checking Michelin.
