Finding basic wheels/tires for 3100 pickup

[gigamanx]

Hey guys, the pickup truck arrived two days ago and two weeks before I expected. Excitement ensued and now I'm coming back down off cloud nine. First things first, the tires are totally shot and the wheels are an odd width for the truck. I need to find some simple 6 lug wheels/tires off crap-list but I have no idea what my max size is for the truck or what I need to watch out for as far as sizing goes. Searching uncovered a need for a larger center to fit the old 3100 trucks and a large enough offset to clear the brakes.




The rears currently are 295/50R15 fronts are 215/70R15

A few options in the local area:

http://harrisburg.craigslist.org/wto/5819056314.html Toyota Tacoma wheels/tires

Seems like it shouldn't be this hard to find some junky old wheels and tires that keep air in them so I can get the car in and out of the garage. TIA
