Asked the same thing in the wheel/tire forum, but normally don't get a response there.... so here it goes:
Ok, so I've been thinking about selling my current wheel set(15x6.5(forget the offset) racing hart cp035s) and found another set I like. My question is:

Will a staggered wheel set of 15x8 and 15x7.5 with a +27 offset fit on my del sol with a mild drop(2 finger gap all the way around)?

Also if I were to get this wheelset would 195/50/15s still fit or would I need to go up to the 205/50/15 size?

 

195's seem pretty narrow on an 8 inch wheel. I've got 205's on my 7 inch wheels and they seem just right.

 

Yeah I was thinking 195s are only good for up to a 7" wide wheel, but couldn't find any real proof

 

start looking up tires you want to buy and the companys' websites should have detailed specs on each tire size including recommended rim width.
