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.

Tyres optimised for electric vehicles.
Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

Surprising amount of wheelspin from standstill in wet for 4wd suv. Also feels like the side walls are floppy on full lock However we have not driven the car with other tyres so nothing to compare against.
03.11.2018fromPete
Have been very pleasantly surprised as to haw good the Tristar Tyers have been I drive a mix of roads Motorway A road and country roads and the tyers have proformed very well in the dry and also in the wet.

03.05.2023fromMr Shane Harris
I had always purchased branded tyres for my cars, particlulary cars that are quick/nippy. I was recommended these tyres by fellow users on Audi forums etc and I must say that these have been brilliant. Road noise is quite, grip is really good both wet and dry and they are wearing pretty well. For a fraction of the cost of premium tyres that were supplied i will defiantley be buying these again in the future.

16.07.2021fromRok Sharma
I drive fast and furious when required or slow and deliberate in slow traffic! I used these tyres on my 5 series BMW 525iSE and were superb! Now on Mrs Peugeot 308 hdi and pretty good!
22.06.2021fromSimon Murrell
Tyres are fine apart from one problem, the rears on a motorway are just really noisy at speed when they get down to around 4mm of tread, so much so that I thought it was a wheel bearing issue, and checked them out, they appeared to be OK, when I fitted new rear tyres the noise disappeared
03.01.2021fromRok Sharma
Great tyre so no complaints
17.11.2020fromCsaba
Incredible tyres. Was hard to find them in the UK but worth every penny. Noise level drastically reduced despite having another top brand previously. Good grip on all types of road. Easily takes on a bit of dynamic driving. Very impressed.

Superb tyres and a good price.
14.10.2010fromSteve the audi driver
Had two sets of these on my previous car (Vw bora) and now on the A4. Always impressed for the price, drive as good as they look, replaced a set of ageing continental contact sport 3 that were terrible !
24.06.2009fromNeil Baldwin
Very very good tyre. Not quite as much outright grip as the new Goodyear Eagle F1 Asymmetric but longer life and quieter.
20.11.2008fromfrog
much better wet grip than my last set of p6000s. will buy again
