Tire pressure 32bb
- Thread starter sonny
- Start date
I am running 650 Denman tires on my 32 BB. Info on the sidewall indicates 60# max for single tires and 50# max in the duals. Tires are load C and rated at 6ply. There is approx 3/4 of an inch between the dual tires. Check duals to make sure they are not rubbing together when under load. There is some interesting information in the 32 to 36 Engine & Chassis repair manual about the effects on the steering geometry when using tires bigger than 600's. I picked that 650's for the higher gear ratio effect on a 5:14 rear drive and they just look better than the 600's. The truck is sensitive to sidewinds. That may be the nature of the beast but if I wear out a couple of tires I might try 600's on the front.

I run a lot less pressure for a better ride,
You can calculate a pressure for the load that the tire must carry.
I once got hold of the formula, and worked it out in spreadsheets.
I asume you now have radial tires, but if you still have diagonal tires there has to be an other power in the uneversal formula.
If you read on the sidewall something like this "maximum load xxxx KG AT yyy PSI ( cold) "then these are the data I need .

There much about tire-pressure, also in English. To download a spreadsheet, click on the line, but not on the name of it, then in the right barr click download.
After download and eventual viruscheck, open it in Excell or compatible program to use it.
2nd from bottom "pressurecalculationwithtemp"can be used her .
But also in the map "äll about tirepressure" "myownformula"in wich I explane the diferent used systems in time, and wher you can make your own pressure/loadcapacitylist .
