sounds like you have had a few toy's....so you should have plenty experience lol,

im running 14x6.5 & 7's all round 65 rear and 60 front profile tires, my opinion 15's i think that's enough, mine are 94 Mitsubishi Galant change the offset on mine by knocking out the center's to suit my style,

i see and hear fellas run 17's but with mod's to the panels, it must ride like a billy cart, rough as gusts!!
some things look great but not always practicable, so do your home work....you have plenty time
