tyre pressure for van

Hi Rag, and Notso,
Sri i should have given more info, name of tyres are MaxMillers, they appear to have very little wear, Ive checked em with a tyre gauge and theyre showing a reading of 40psi , Im assuming they are car tyres as the size on the sides say
175R13...

The age of the tyre that Roughasguts mentioned is very important. If you have just bought this van, and it is a few years old, then the tyres may be too old to be reliable. Many vans don't do a lot of ks each year so some tyres could be way past their use by date but still have plenty of thread left.

The date of manufacture will be on the sidewall. Look for a slight depression with numbers in it close to the tyre bead. It will usually be about 25 mm long, often with rounded ends, and may have screw head marks at each end. It will look different from all other writing on the tyre. The manufacturer attaches a little tag into the edge of the mould each week and that causes the depressed area and numbers. A reading like 2106 will mean the 21st week of 2006. If you find only three numbers then the tyre dates back to before the year 2000. If the tyre is more than about six years old then buy new ones.

When you want to know anything about pressures, or anything else about a particular tyre, then try ringing the customer information number for the tyre manufacturer. It will be on their web site. I do this whenever I buy a new set of tyres. They will even give you the amount of weight each psi will support and this can vary even between different model tyres of the same size.

Tyre sidewalls usually have a designed flex point. Different pressures and rim widths can change this and have an effect on tyre temperature.

175R13 doesn't tell us much.
After that it should have LT or C if not they're car tyres and not recommended for trailers (vans).

I'e been using a similar chart for may years. I usually use it as a starting point and then invoke the 4 PSI rule (Bottom of chart) to get the correct tyre pressure for the weight being carried.
Note: the chart is for LT or C radial tyres.

hi Ozjohn,
thanks for the info
cheers

Mate if the tyres are more than 5 years old get rid of them immediately.

Forget about good tread etc,, the tyres today de-laminate and fail regularly when they are about 5 years old.

Hi Gimelsol, racey and boo, thanks for the great advice will carry out your
suggestions, have just bought a 12v compressor..tomorrow will check the info on the tyres.... does it make any diffierence if I'm only doing hwy travel as to the tyre type.
cheers
