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.
How do I check my tyre size?
How do I check my tyre size?
You are looking for three numbers (occasionally just two numbers) shown on the edge of the tyre, e.g. 195 / 65 - R15
![Tread width, Profile Height, Rim Size](/images/tyre_size.png)
For info, what do these numbers mean?
195 is the tyre width in mm. 65 is the profile, the distance from the edge of the rim to the top of the tread (the tyre "wall") in mm, expressed as a percentage of the width, i.e. the tyre wall is 127mm high in this example (195 x 65). 15 is the "rim size" in inches (a complicated measurement).

Polaire Steel Grip are the most modern and innovative single-fixing, front-fixing chains that we know about - see below for more information about what these words mean! - and are also excellent value for money.
Steel Grip have been improved this year with ice-breaker steel traction plates - note that there are several overseas internet retailers dumping their old stock into the UK market this season.
General features of Polaire's Steel Grip: - These 9mm front-fixing chains are suitable for almost every vehicle, especially those which can't use traditional snowchains because there's not enough space behind the wheel, or because there's not enough space to fit them - you'll remember that to fit traditional chains you need to be able to push both your arms into the space between the wheelarch and the top of the wheel
- Polaire Steel Grip are unusually quick to fit because they can't get tangled, so no time is taken in getting them ready for fitting; if you’ve used traditional chains before you’ll know that untangling traditional chains often takes much longer than fitting them, however carefully you put them away in their box
- This latest version of Polaire Steel Grip has ice-breaking traction plates placed across the road contact surface, to improve grip when climbing or descending hills; there are also occasional diamond-shaped sections to improve lateral stability, especially important when cornering
- Once set for a particular wheel (which only takes a couple of minutes), Polaire Steel Grip are tensioned against the wheel by swinging a flip-over lever from one side to the other - they really are unusually quick and easy to fit!
- The same one-piece adapter fits all wheel bolt sizes from 17mm to 23mm, so (unlike competitor systems) there are no fiddly parts to assemble or to lose
- They have all necessary snowchain approvals, including TÜV, ÖNORM (Austria), B26 (France, snowchains compulsory) as well as various car manufacturer/OEM approvals
We think they're excellent.
More about Polaire's 'front-fixing' system:
Every ladder track/front-fixing chain system on the market, except for the Spikes-Spider system, works on the principle of fixing the chain to a single wheel bolt, and then bracing against this wheel bolt fixing so as to hold the chain against the road contact surface of the tyre. There's no need to grovel about behind the wheels, as is required for fitting the traditional type of diamond pattern chains. Front-fixing systems don't leave any chain behind the wheels (so nothing can get snagged), and the front-fixing chains can be pushed into what is often a tight space between the top of the wheel and the wheel arch. (For info, all Spikes-Spider systems fix to more than one wheel bolt - they have a patent on this - which is considered to be an even stronger fixing.)
Polaire’s GRIP and Steel Grip fixing system is better than other single-bolt fixing systems because: - the same patented adapter fits all wheel bolt/wheel nut sizes from 17mm to 23mm
- the standard adapter, working together with a cord tensioning system, is suitable for approximately 95% of alloy rim shapes; shorter and longer adapters are available for the extremes. If we know about alloy rims that need extra adapters we'll tell you. (Note that other brands of front-fixing chains are supplied with a bag full of different bolts, spacers, and adapters, to take account of different wheel rim shapes; the Polaire system is, in contrast, relatively extremely easy to set up for first time use, because the cord bridges the gap between the adapter and the tensioning system.)
- the chains are held onto the wheel fixings with Dyneema cord – with a breaking strain in excess of 1 tonne!
- the Dyneema cord pulley system makes it relatively very easy to tighten the chain against the wheel
- each chain only needs to be tensioned the first time it's fitted - from then on you just flip a lever from one side to the other to lock it into place at the correct tension
FAQ - Polaire Steel Grip or Polaire GRIP?
- Both versions are suitable for all vehicles up to 3.5 tonnes (including the load)
- the GRIP is designed for snow but also to be used for short distances on tarmac; Steel Grips should be removed before driving on tarmac because they'll wear very quickly
- Both chains have the same excellent front-fixing system
- Both chains have very similar performance results (comparing GRIP with the latest version of Steel Grip that we're selling)
- Both chains have all necessary snowchain approvals
If you can't decide, we recommend that you choose the polyurethane GRIP, because of its ability to be used on tarmac - a very useful feature for typical UK winters. Polaire introduced the Steel Grip because the French market was slow to respond to the idea of 'plastic chains'. If you still can't decide, toss a coin (!) - we are confident that you won't be disappointed with either of these excellent chains.
We're also showing you a range of other winter motoring products which we're selling here at market leading prices, including a snow and ice windscreen protector, a telescopic snow shovel, and a snow brush - all of these items are almost essential kit for winter weather, especially we suggest the snow brush.

Delivery FAQs
When will my order arrive?
There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Express Delivery orders placed on a Friday (before 1pm) should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday or Sunday should be delivered on the Tuesday or Wednesday. The arrangements for Very Heavy Items are different and are shown above.
What about Next Working Day delivery?
Most Express delivery orders will arrive on the next working day, if the order is placed before the cut-off time (see above). Some will arrive on the second working day if there has been a "split-delivery". So-called “split deliveries” happen when the couriers do not have enough trailer space for everything that should be moved around the UK, so they will load what they can and leave the rest for the next trailer.
Is my delivery day guaranteed?
No retailer or courier company can ever "guarantee" a Next Working Day delivery. As well as split deliveries, all courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.
Do I need to be at home?
We are very flexible with our deliveries and will aim to deliver to an address which suits you – this does not need to be your home address. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.

There are two parts to our snow chains offer this year:
(1) Clearance prices on many top branded snow chains, including RUD and Thule - an amazing opportunity for those who are quick off the mark! Thule (who are the biggest brand in the car racks market) have sold their snow chains division; the same chains are now being sold under the König brand. Thule branded chains have the same specifications as the König branded versions - all that has changed is the name on the chain and the name on the box.
(2) Multibuy discounts - significant discounts if you buy two pairs of snow chains at the same time, or one pair of chains and one pair of AutoSock: If you do either of these things, we will discount the snow chains as follows:
- König, Polaire and Spikes-Spider snow chains - at least 10% off!
- INNO, Maggi, RUD and Thule snow chains - at least 20% off! Up to 30% off where we have large overstocks.
As usual, you change the quantities in the Shopping Basket.
Many customers will, for example, use snow chains on their driving wheels for Alpine use, and use AutoSock on the non-driving wheels, especially if these are the steering wheels. Also note that AutoSock work very well in very wet snow, even on slush, where snowchains are often not suitable because they can't get any grip in the snow. So having both AutoSock and snowchains makes sense from at least two different perspectives.

Here are a few fitting tips which we hope will help you to get the best from these excellent snow chains. The pictures show the polyurethane GRIP, but the fitting system is the same for both the GRIP and the Steel Grip. First time fitting: In summary, you need to get each chain onto its wheel and then adjust the length of the Dyneema cord; once this is done, future fitting will only require you to push the chain over the top and sides, clip onto the adapter, and flip the lever. In detail: - Remove any plastic covers from one wheel bolt/nut on each wheel
- It's easier to use the separate Allen key provided to fit each adapter, but the Allen key on the end of the connector is always there as a backup
- Place the chain over the top of the wheel in an X shape, as in "10 minutes to 2"
- Take up some of the slack in the cord by turning the tensioning wheel - it's much easier to turn the wheel from both sides, using e.g. one thumb and one finger, than to try and do all the work with your thumb - see picture = Fitting tip (1)
- Flip the red tensioning lever, move the vehicle half a wheel revolution, and push the remaining chain over the top of the wheel. Now it's time to tension it correctly
- The correct tension is someway beyond the perpendicular, maybe about 110 degrees, as shown in picture = Fitting tip (2)
Other fitting tips: - When you clip the connector to the adapter, the cord should be close to the centre of the wheel
- It's a lot easier to flip the tensioning lever if you use your other hand to apply some pressure to the ring, see picture = Fitting tip (3)
- Remove the adapters when you no longer need to use the chains but, if it's snowy weather, and you're expecting to be fitting them again soon, and you aren't going to be travelling at high speed, then it makes sense to leave them in place
And finally, a reminder that the maximum permitted speed with the chains fitted is 30mph (50km/h).
