Snow chains are one of the most important allies when it comes to improving safety, reliability and efficiency during winter driving.
For years, König has been supporting public transport operators and passenger transport professionals by offering snow chains for buses and coaches designed to meet the most demanding operational requirements.

Within the Professional segment, the key models are:
Below, we analyse each solution in detail, comparing mounting systems, technology, applications and operational advantages, to help professionals choose the most suitable snow chain for their fleet.
König K-Summit Pro
Zero-clearance snow chains for buses
The König K-Summit Pro is a snow chain without any internal components inside the wheel arch (zero clearance).
This feature makes it the ideal solution for buses and coaches that do not have sufficient inner wheel clearance to accommodate traditional snow chains.
It is particularly suitable for modern vehicles with sensitive components or limited space behind the wheel.
Available in 7 chain sizes (K105, K106, K116, K117, K127, K128, K138), the K-Summit Pro features an adjustable tread, capable of covering up to 15 tyre sizes per chain code.
A major advantage for fleets: the same chain can be used on multiple vehicles with different tyre sizes, simply by adjusting the elements according to the instructions provided in the user manual.
Automatic, external mounting
Thanks to the absence of internal components, the K-Summit Pro is mounted exclusively from the outside of the wheel, allowing for faster, safer and cleaner operations.
- Quick fastening to the two supports installed on the wheel rim at the beginning of the winter season
- Adjustable retaining straps, compatible with hubs up to 175 mm protrusion
- Patented tensioning wheel, which loads the elastic arms effortlessly
Once positioned, simply start driving: the chain automatically centres itself on the tyre after a few metres of driving.
Technology and performance
The tread of the König K-Summit Pro consists of:
- 5.60 mm D-profile links
- Welded bars with a specific design that prevents tyre damage
The spring-loaded adjustment elements reduce dynamic lift, improving stability, durability and driving comfort.
The tread is connected to the rest of the chain via high-resistance plastic plates, designed to withstand:
- corrosion
- freezing temperatures
- mechanical stress
The chain is supplied in a stackable plastic box, ideal both for warehouse storage and for placement in the vehicle luggage compartment.

König Coach Master
Professional snow chains for buses with reduced clearance
The König Coach Master is designed for installation on buses and coaches with limited space in the wheel arch or twin tyres.
Its rigid arch structure allows installation without lifting the vehicle, even in challenging operating conditions.
The inner arch locking system can be operated from the outside, avoiding difficult or physically impossible manoeuvres inside the wheel arch.
The chain comes fully assembled and requires no preliminary adjustments. Installation simply involves:
- fitting the chain over the tyre
- tensioning it using the steel side chain tensioner
Intuitive Top-Down mounting
The Coach Master features a Top-Down mounting system, where the chain is fitted from the top of the wheel downwards.
It is equipped with:
- an anti-return device, preventing accidental release
- a short-pitch tensioning chain, ensuring even and precise tension
The terminal with spring and simplex hook makes fastening, unfastening and retensioning quick and easy.
Technology, comfort and grip
The tread of the König Coach Master is made of:
- 6.00 mm round-section links, improving driving comfort
- a smooth profile without sharp edges, reducing noise and vibration on icy and snowy roads
The high number of diamond patterns on the tread ensures:
- continuous grip
- excellent performance when steering
- reduced vibration while driving
The chain is supplied in a durable and compact RPET bag, ideal for professional transport and storage.
