Hi all. Some input required from you all. When towing your van are your tow vehicles tyres: A. Over inflated B underinflated C. Take a chance just hook it up and go?

Hi Scoot Get yaself wanna these www.happywanderer.net.au/page.asp?parentid=19&parent2id=50&parent3id=62i would imagine it would go off if ya run over the neighbours cat as well. looks like a limit switch with rod attached. The tyre deflates and it comes in contact with the road , it bends back and sets the alarm off. Only good for letting you know the damage is already done. If that dont work try no more than about 32 lbs in your TD tyres. gotta remember that air expands when it gets hot so on a long trip they could end up around 40lb. TDs weigh bugger all and you could probably go as low as 24 P.S.I better to let them bag out a bit than to run them as hard as a brick. Cheers mate reddo

Heya Reddo, Sorry matey. I didnt write the posting very well. What I meant was the tyre pressure in the wheels of the tow vehicle not the van. Scoot. PS yes and those other things probably are just one more wanky thing

I read somewhere that you should bump the tyres of the tow vehicle up by 4 or 5 lbs when towing.......yes air expands when heated , but so does a tyre.....and if it is underinflated the heat buildup will cause the tyre to become VERRRRY flexible and explode (blowout) Cross plies are the better tyre for caravans ets because of minimal sidewall flexing.............small truck radials are the next best option because of their stronger sidewalls.

Use the 4PSI rule.
Get yourselves a good tyre gauge and check the pressures cold, then drive for half an hour or a bit more at highway travel speeds then stop and recheck the pressures with the SAME gauge, they should have increased by 4 PSI.
If they increased by more then the starting pressure is to low, if they increased by less the starting pressure is to high.
This rule is works for both car and van, it gets the pressures right for the load carried by the individual tyre and works for car sized tyres, for larger fourbie sized tyres the figure to use is 6 PSI.

No worries Geoff. I did the same myself some time back before I tried to register mine - hence I got it through without significant problems.
