Why it's important to select the correct vehicle and tyre size
Vehicle
There are a surprising number of vehicles that cannot use traditional snowchains, the types that put chain on the inside of the wheel as well as on the tread. This is usually because there is not enough space between the wheels and the shock absorbers; this can be a problem for ordinary SUVs and 4x4s as well as for high performance cars.
You will find this important information in your car handbook - please check this before using your snowchains! Our database is intended to do the basic work for you but, with so many new vehicles and tyre sizes, it should only ever be treated as a guide.
Tyre size
Please also check your tyre size - if you buy incorrectly-sized chains they will be either too tight or too loose.
Ladder track chains
The good news is that car handbooks usually only refer to "traditional snowchains". Ladder track chains such as the Polaire GRIP and Spikes-Spider range only put chain over the tyre tread, so are not subject to these restrictions. They are also ideal for use on rear wheel drives where there is minimal space between the top of the wheel and the wheel arch.

It's really important to select the correct vehicle, paying attention to the year of the manufacture
Restrictions for your vehicle...
Our snow chains suppliers tell us that your vehicle and tyre size combination is not suitable for any traditional chains, and most automatic chains; this is probably because any chain links placed on the back of the tyres are likely to snag on the shock absorbers. We believe that all the chains shown below are safe to use; for example, ladder track chains do not put any chain behind the tyres.
AutoSock are simple to fit and give extraordinary grip on ice and snow. Keep a set in the car for UK use!

The K-Summit is what we usually call a “Ladder track chain”, because a ladder of chain is placed around the face of the tyre, braced off a mechanism which is fixed onto one wheel bolt. There’s no chain inside the wheel.
These chains are particularly suitable where there’s minimal distance between the wheel and the wheel arch, a typical feature of many rear wheel drives with large alloys. If you can't get your forearms into this gap then the K-Summit is your only König option.
They’re also easy to fit and remove and, because you don't have to put your forearms over the tyre, you shouldn't get dirty slush on your forearms or clothes.
