Q/A

How fast can I drive with the Spikes-Spider?
According to the law, 50 km/h is the maximum speed limit driving with snow chains. However, you should always adapt your driving style to accommodate the road and traffic conditions. Hard, abrupt braking, wheel spin and "sport like" cornering, on all snow chains, leads to increased material wear and tear and in many cases to vehicle damage.

What big advantage does Spikes-Spider have over conventional snow chains?
The unique pre mounted adapter, which can remain on the wheels all  winter, ensures that there is not a snow chain to rival its simplicity and speed to fit. Especially when winter breaks suddenly and unexpectedly. Emergency services, who for many years rank amongst our most satisfied customers, can attest to this important factor.

The Spikes-Spider Compact is, like ALL Spikes-Spider models, a fully fledged snow chain, with all necessary standards and approvals, thus allowing them to be driven on roads where snow chains are compulsory.

Can the Spikes-Spider be driven in Switzerland?

How far must the screws be tightened when mounting the adapter plate?
In general all components must be tightened with the special torque wrench supplied.

After a trip I can barely pull the red handle on the locking disc out.
What can I do?
Depending on how the vehicle was parked with the mounted Spikes-Spider, it is possible that  the system has come under tension, and, as a result, the red locking lever cannot be easily freed. You can reduce the tension by vigorously moving the black locking disc with both hands, to the left and right.

Are all Spikes-Spider models adjustable for all types and sizes?
All Spikes-Spider snow chains are adjustable up to 20cm, which allows the Spikes-Spider to be used on other tyres with different dimensions.

Why are "Spikes-Spider" products offered at significantly lower prices on the Internet?
Unfortunately these are NOT Spikes-Spider products. They are illegal copies with a vastly inferior quality, often from an Asian manufacturer. The approvals and permits are often fake, thus making the product an unapproved and unaccepted snow chain. Often original pictures of the Spikes-Spider are used so as to convince the customer they are buying the original product.

Why buy a Spikes-Spider when on the Internet conventional snow chains are available at very low prices?
Agreed, there are very low prices for snow chains, from the Far East. First and foremost put your trust in quality, after all, it is your safety we're talking about.
