New potential wheels.

[Meat Head]

I found a set of the 5 spoke Carrera wheels that I like. They came off of a 2004 Carrera and have almost new Sumitomo HTR IIIs on them.

The fronts have 225-40-zr18s
The rears have 285-30-18Ss

Will these tires and rims fit a 1998 Box?? I know I will most likely need spacers but what size???

I don't know much about Sumitomo tires but after reading a few posts on here it seems like people like them.

What would be a fair price???
