Husker,
thank you for that link. I will definitely continue posting here. Help from my truck's country of origin is absolutely invaluable!
Longbox,
here in Germany the load range for truck tires is way different. The minimum I can get in this size is more than enough needed for the 3/4 ton trucks. The question is if these tires were originally mounted since I cannot really check the speedo. The needle has gone. I consider to get a set of American Racing AR23 which are only available in 16x8. I think they look great and the tires for them according to the current size are 30% cheaper.

By the way, I hope my english isn't too bad for you?
