Think you may also want to think about ambient temperature and how far you intend to drive tyres get hot and pressures increase

Yes, I always check, and set pressures early morning when they are cold👍

Probably find motorhome manufacturers set tyre pressures at max for tyres - i tend to run them at 55psi which is close to 3.5 bar but thats my choice

I found that the Continental recommended pressures for my actual axle loads where not to my liking, I upped them a little, this (IMO) improved the handling, and gave a lot more flexibility to loading.

So, very prompt reply from Continental, with recommended pressures.
On axle weights provided, 3 bar front and 3.25 bar rear.
Quite a bit less that the 5.5 suggested on the sicker inside the door on the van and also from the dealer upon collection of the van.
It does beg the question, who do you believe. Must say, I am inclined to go with the tyre manufacturer, as the current pressures tend to jar your fillings😂👍
Work out the correct pressure for yourself. It really is easy.

1. Weigh the axles (separately) From that, calculate the load on each tyre.
2. Read the writing on the tyres Tyres are always marked with a maximum pressure, which is not the maximum pressure they can take, but it is the pressure they should be at their maximum load. They are also marked with a load rating code (which you need to look up on the web to convert to a load in kg).
3. Calculate the correct pressure. It is a simple proportion of the maximum load.
For example, if the tyre is rated to carry a maximum of 840kg at 65psi, and the actual load is 700kg, the correct pressure is 700/840*65 = 54.17 psi

This is absolutely the way to go in working out your tyre pressures - its too important to guess, or not take the time to research, or better still find out on a weighbridge, axle weights.
The only deviations would be for example driving off road, and needing to lower pressures for sand or possibly higher for driving over 70 mph...
in h's post should be a 'sticky' on the forum somewhere!!

As posted on another forum by someone who has investigated accidents, doing this yourself could leave you in a very difficult situation, whereas taking a manufacturers recommendation might prove much easier in court.

Yes, there is always someone who will post misleading statements in "another forum". You have to decide for yourself.

We bought this van in December obviously not really used so far. Just fitted the rear bike rack and loaded up bikes tables chairs etc to go to the local weighbridge no clothes loaded no food 20 litres of water me the wife and the dog also not fitted gas yet oh and a full tank of fuel
Came in at 3560:mad:
I was expecting to have quite a bit spare. Only have 40kg left on rear axle. Not happy but shows the value of checking the weight
Under the bed is empty loads of empty cupboards
Manufacturers should not be allowed to sell vans that are not really usable at 3500
It will now cost me upwards of £700 to upgrade to 3850 to make the van useable
On the bright side I don’t have to change the tyres.

Many people want big vans, this often means large rear overhangs, only really works with heavy duty rear suspension such as you find on the Maxi chassis.

It is right on the junction of the M9 ( J10 ) and A84.

1 Ariel view, 2 view from main road, 3 view of entrance, 4 view as you turn in, 5 view of the actual weighbridge.

The readout is at the top of the short pole with the instructions taped onto it and the dynamic weighplate is in the foreground of the last screenshot ( 5 )

Have pen and paper ready unless you have a very good memory, it will give you 3 readings, front axle, rear axle, total gross weight.

This is brilliant pal. Really appreciated. Didn't realise such places existed. Will visit as soon as back on the road for reassurance.

Thanks again.

It occurs to me, that if the bikes can fit in rear garage you would be much better off.

On this van it is not really a garage as such. I've checked and a folding electric will fit under beds and bring weight forward. and will help a bit but as we already have good Trek bikes its almost catch22 now. We are hoping to go touring for longer periods soon so upgrade to make sure we are ok seems the only way forward.

This is a prime example of a van that could very easily be overloaded.

Give SvTech at Leyland a call 01772 621800

They will tell you what can and more importantly what cannot be done.

Have your V5C and tyre sizes / load ratings ready at hand as they will need this to give you the correct information, the advice is free of charge.

I'd lose the bikes i take dog away and just walk everywhere with the dog dont know what they weigh but wont be that light

Thanks for the info. All done today just got invoice through. £700 all in with VB air assist on rear. Tyres are ok to up to 3850 looks like an easy job and they send the part to fit. more importantly it ups the rear axle to 2250 so loads spare now thankfully.
Paper exercise would have given 3650 with all the restrictions and no real benefit as rear axle stays the same. just ordered twin gaslows now so all ready for the big tour
