S10 wheels are a no go. The tracker pattern is 5 on 5.5". Don't know what others will fit..late dodge 1/2 ton pickups and pre 97 ford 150's have the 5 on 5.5 pattern, but don't know about the center hole in them.
No way. Remember, Trackers are really just Suzuki's in disguise. They share little to nothing in common with other Chevrolet models.
FWIW, S10's have a 5 x 4 3/4 bolt pattern, and the hub hole is much smaller. Offset would depend on if they came from a 2wd or 4wd.
