Before you fit it

Four numbers that decide whether a load arrives with you or leaves you on the hard shoulder. They cost nothing to read.

The limit is the car, not the tow bar

The limit is the car, not the tow bar

A tow bar carries a D-value; your car carries a homologated towing mass written in its registration document. The lower of the two is your limit, and it is the car’s figure that a roadside check reads.

Seven pins run the lights. Thirteen run the lights plus the permanent live and the fridge in the caravan: a trailer with its own battery needs thirteen, and an adapter does not create the two extra circuits that are not there.

The roof limit includes the bars

The roof limit includes the bars

Most cars allow between 75 and 100 kg on the roof — and that figure counts the bars and the box, not just what you put inside them. A 20 kg box on 6 kg bars leaves you about 50 kg of luggage, not 100.

Put the weight low and central, strap it to the box’s own anchor points rather than letting it slide, and stop after the first 50 km to check the clamps again: everything settles once.

Chains go on the wheels that drive

Chains go on the wheels that drive

Front-wheel drive, chains on the front. Rear-wheel drive, chains on the rear. On four-wheel drive the handbook decides, and it is usually the front.

Fit them before you need them, not on the slope: drive 50 metres and re-tension, because a chain settles into the tread and what was tight is now loose. And check the clearance your car allows — on some cars only a fine-link chain, 7 or 9 mm, passes between the tyre and the strut.

A mat that slides is a brake that does not work

A mat that slides is a brake that does not work

Car floors have fixing points for a reason. A mat laid loose on top of the original one walks forward a centimetre at a time until it is under the pedal, and you find out at the only moment it matters.

Never stack two mats, and if the new one has no clip for your car’s fixing, it is the wrong mat — not a mat that needs a little trimming.

Find a fitter near you

A tow bar is wired into the car’s electrics and a roof bar is only as good as the clamp. This is where to look when it needs fitting properly.

Where to go next

How we earn. When you buy from a shop we showed you, that shop pays us a share of the sale. You pay the same price. We never change the order of the list for money: the cheapest one we found is always first.

Questions

Will any tow bar fit my car?

No. A tow bar is approved for a list of models and body shapes, and fitting one outside that list makes it unapproved even if it bolts up. Look for the bar sold against your exact model, year and body.

Detachable or fixed?

A fixed bar costs less and never gets lost. A detachable one keeps the parking sensors usable and the bumper clean when you are not towing. Mechanically they carry the same load.

Seven pins or thirteen?

Seven for a trailer that only needs lights. Thirteen for a caravan or anything with its own battery, fridge or interior lights: the extra circuits do not exist on a seven-pin socket, and an adapter cannot invent them.

How much can I put on the roof?

The figure is in your handbook, usually between 75 and 100 kg, and it includes the bars and the box. It is also a limit on how the car behaves: a loaded roof raises the centre of gravity and lengthens braking.

Are snow chains compulsory?

It depends on the country and often on the road and the date, not on the weather. Several Alpine regions require chains on board or winter tyres between November and April regardless of whether there is snow that day.

Do you sell these accessories?

No. We compare what the shops are asking and send you to the one that delivers in your country. If you buy, that shop pays us a share: it costs you nothing more.
