Do you find your trailer/caravan/camper to be unstable when towing? Don’t rush into expensive anti sway systems just yet, chances are your problem could be as simple as incorrect tyre pressure.

Fortunately, tyre manufacturers print pressure and load specifications on the tyre sidewall, so it is possible to calculate correct tyre pressure at any given load. Ideal tyre pressure depends on the weight that the tyre is carrying and also the load specification of the particular tyre (not all tyres are the same).

If you have a single axle trailer that weighs as much as your tow vehicle, it should come as no surprise the the TWO tyres supporting your trailer will require different (and probably much higher) tyre pressure than the FOUR tyres that are sharing the weight of your tow vehicle.

The question is……. how much pressure?

Our Tyre Pressure Calculator will take the trial and error out of it for you and provide you with suggested tyre pressures for specific weights. These calculations are made from the actual weights that you provide and the actual tyre specifications that you obtain from your trailer tyre sidewall. What that means to you is that the calculated results are not a guess or a “one size fits all” estimate, they are genuine calculations for your specific trailers weight and tyre combination.
