My 240z has the stock 4 LUGS black Pearl wheels with 14 inch tires. I would like to upgrade it to 15 inch wheels but without doing any mods to the suspensión or brake system. I really like these wheels:

What type and size of tires will i need?

Probably too late for advise but stay within the original tires diameter approx.24.5" with 0" offset and you should be fine.
