For all you tire guys, how do you determine what the correct tire pressure is for the type of tire your running on your car.
Example, my 1964 3000 Mk III drivers handbook mentions Radial-ply tyres (Dunlop SP41) on page 30.
On page 4, Tyres:
Size, 5.90 - 15 tubed.
Front, 20 lb. /sq. in
Rear, 25 lb. /sq. in
Maximum performance speeds:
increase all pressure by 5 lb./sq.in
I'm running Michelin ZX, 175 R 15.
Sidewall says:
Max Load 650 Kg 1433 lbs
Max Press 340 Kp 50 psi
How do I determine the psi for front and back.
Yesterday, someone told me he runs what the tire says on the sidewall. He told me he would run both the front and back at 50 psi.
Also note that the Michelin ZX says tubeless. I'm running tubes. So, does running a tube affect the psi decision.
Your thoughts?
