I everyone I'm new at this.
I just got a set of Akita 420 racing wheels 17"x7 4x100 40 offset for free
Will they fit on a 94 civic coupe with stock suspension..if so what is the best tire size to use

 

I had 18's on mine with 2 inch lowering springs and they fit fine. Only problem was they rubbed a bit when i turned. They are now on my 95 coupe and they fit fine. I even have coilovers on it. So yours should fit fine.

 

i normally run my 17x7 with 42 offset just fine with 215/40/17's. the ride quality is actually not bad with the 40 series, a 45 series would also fit your application and create a better ride for you. im 2.5" lowered from stock and i have no rubbing issues lock to lock.

 

Will 205/40/17 work.according to tirerack.com and procivic.com they say to use 205/40/17 or 195/40/17 not sure what would be the best...and also you saying ii could use 215/40/17..just trying to make it so I don't rub
