so go out to your truck, jack it up and put it on stands and pull a wheel off. take that same jack and jack up your control arm all the way (as if your layed out) measure from your spindle to the firewall, or whatever else might be closer to your spindle than that. that measurement will give you half of your overall diameter of tire you can run. so now you know how tall of a tire your running, take a plumb bob and hang it from the inside of your fender, and use a measuring tape and measure from the wheel mounting surface to the plumb bob string. give yourself a little extra clearance - say half inch... that is your measurement for front space. your overall width wheel minus your front space will give you your backspace. (this is in inches) your offset is in MM and i don't do that.
so back to the tire diameter. say it's 24 inches... a 205 40 17 is 23.5 inches tall, so you could run that. a 215 35 18 is a cunt hair under 24 so you could run that too.. you'll have to get your measurements and search around for what you want.
