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.

I’ve never had these tyres, they were cancelled as you emailed explaining they had been returned to the warehouse
02.02.2022fromDave parker
Replaced all 4 tyres Goodyear Eagle 1 for the Toyo Price sport due to the the fact that Goodyears were old 9 years and they had become stiff and the flexibility of the rubber had become poor ride lack of grip and dangerous in the wet. Having said that our car is only showing 50,000 miles so we only run it like you are supposed to is sun out top down. Now with the new Toyo sports we feel safer with much more predictable feel and grip would definitely recommend these tyres especially when on promotion and would buy again but as I said we don't do many miles and will probably replace these not because of wear but down to age related issues like we had to with F1 s but must say the As 3 is like a different.car for the better.

Most of the miles i am driving on motorway but i drive in town too. I can't say nothing wrong about this tyres. Very pleased with them. Tge tyres are not noisy, very comfortable, very good grip in dry and wet conditions. Very good quality overall for 108£ each tyre considering the size 255/45/19. My next set of tyres will definitely be the same, TOYO Proxes Sport.

Tyres feel grippy and safe in all conditions. Wear rate is reasonable . Ride comfort and noise ok , and better than previous premium tyres.
