[T2] tire pressure 71 westy 185/R14

[OKearney]

Hi
I have Hankook 185/R14 on a 71 westy - ie full furniture and  heavy.   
I have been running with 50 all around - someone's recommendation.

I think it too high, PLZ , anyone with same tires and same rig, what  
are your inflation prefereces?

thank
John
