what i mean by OIIIIO is jeep........
will jeep 4x4 wheels fit my 98 4x4?
seems like i seen a jeep with 4x4 blazer wheels
anyone know?

 

you would have to check the lug spacing on the wheels. i dont think they are the same.
you could do it with wheel adapters though. so yes it can be done..like anything some money and parts will do it.

 

They are different, xj's, yj's, tj's have 5x4.5, blazer's are 5x4.75

There was one style of jeep wheel fairly similar to the older blazer wheel, I'd bet that's what you saw.
