No year s-10 wheels fit our cars 91-96. The s-10 bolt pattern has always been 4x4.75 since 1982.the caprice bodied roadmasters take a 5 on 5 rear wheel drive offset. the fwd wheels will not fit. half ton 2wd pickups and older s10 wheels will fit.
I think early astro vans may fit, but I do know that at least from 95 on until 03 when they went to 6 bolt that the bolt pattern was 5x5 and will fit. As will full size chevy van and c10 and c1500 pickups up to 98.
