Could somebody please let me know the correct tyre pressures for Bridgestone Duravis 205 70R 15C tyres which are fitted to my T4 Camper?
There is no sticker on the driver's door, nor any info in the handbook.
46 to 48 front 44 to 46 back, i roll on standard 195 70 15 steels, was told 55f 58b felt every bump, 48f 50b is so much better, its also about how it rides and its only the driver who can judge this, they way i was told is after you come off a dusty road look at how it sits on your tyres, front coverage should be all tread with appox inch tread each side and back have about 5mm each side, bit hard to explain.
The correct tyre pressures depends on the weight of your van (including passengers and luggage so this will vary), and the size and make of tyres. You will need the following information to calculate correct PSI for any given combination:
(Gross) weight of vehicle
load rating of tyres at max PSI (the sidewall will have this information - something like 600kg at 44 PSI etc)
For example, if your car weighs with some passengers and baggage say 1700kg
Goodyear Eagle F1 GSD2s are rated for 545KG at 44 PSI so:
545kg x 4 = 2180kg (max load)
2180 (combined max load) ÷ 1700 (vehicle weight) = 1.28
44 (max tyre PSI) ÷ 1.28 = 34.31
So you should inflate your tyres to 34 PSI / 2.4 bar in that example.
Just substitute your vehicle weight and tyre max load
You may wish to work out the difference for front and rear axle
The following weights are for the maximum permitted axle weight that is recommended by the manfacturer. The load rating represents the minimum load rating needed for the highest of the two maximum permitted axel weights.
The following chart is meant only a guide and you should always check your individual vehicle for the precise axle weights.
Model Year Wheelbase Front Axle Weight Rear Axle Weight Combined Axel Weight Minimum Load Rating*
Van 800 1990 - 1995 SWB 1200kg 1200kg 2400kg 90
Van 1000 1990 - 1995 SWB 1350kg 1380kg 2730kg 95
Van 1200 1990 - 1995 LWB 1430kg 1460kg 2890kg 97
Caravelle 1990 - 1995 SWB 1350kg 1380kg 2730kg 95
Chassis Cab 1990 - 1995 1430kg 1460kg 2890kg 97
This has been very helpful to me in getting good guidance to inflate my tyres at the correct pressures
The tyre supplier gave me pressures a bit high it would appear
Thanks again to all who replied
As a rookie this is a great forum to learn from
The pressure will also depend on the load rating of the tyre, you need that really to work it out. You also need an idea how heavy your van actually is now it's a camper on each axle to help work out the correct pressure, too low and you risk blow out due to the side wall over heating due to being flexed too much, too high and the ride will be bad and you will lose grip.
There is a proper table which I can check at work that uses the load rating, I will have a look for it when back in tuesday
