What size tires will fit my 22inch rims

it depends on the vehicle...if you are going say from an stock 18" wheel to a 22"- you might as well be ready to replace your inner and outer tie rods within a year. possible even upper and lower ball joints......you really shouldn't go up in wheel size "rem that is" more the 2" difference...the parts on your veachel were made to support the stock wheels, going up in size produces more stress and wear and tear on the front end.
