Hello

I need you help.
I am trying find out tire options for Highboy.
What is biggest(highest) tires from factory and I need some brochure or facts for inspector.
In my country, Finland, law is pretty tight.
I can increase size 10% or 3 inch from biggest stock size. No more.
My dream is build streetlegal Highboy as high and big tires as possible.
I hope that someone could help me and give exact information. With documents if it is possible.
I dont have a car yet, but if I get facts about tires, I try buy "Highboy".

Thanks and sorry

 

Completely off of memory so here goes.

Original rims should be 7x16 splits
Original tire size converted into today's system is 225/85/16
basically skinny 31" tall tires

 

Any other options? 7.50-16?
Any manuals or sites, where I can find.
