hello have a 03 king ranch have a leveling kit and extra leaf in the back wondering maximum tire size i can go witrhout trimming and maybe some sites to order rims and tires cheap currently have stock 17' rims with a 265 on them
this should last a year or 2 till i get board and put a 6'' lift or chimp out and put a 3'' body. i have a programer cold air intake beefed up tranny looking for tires for now.

 

If your King Ranch is a 4x4, you can fit up to a 315/70-17 (35x12.50) by using the oem wheels. This is an extremely tight fit and they will rub the frame slightly at full lock.
I'd check with one of our site sponsors like Tire Rack.
