225/50R16"s

[DRONE]

Have them on the rear and 205/55-16 on the front. of the 1987 Coupe
Can I just buy 245s for the rear and put the 225s on the front without any major mod's (new wheels, spacers, ect.)

Depends on your wheels, how low the car sits, how much camber you run, etc.

First, to even consider this you need 7" & 8" wheels, not the more typical 6" & 7".

If you have 16x8 for the rear, the 245/45 is pretty straightforward.

But the 225/50 on the front will be tight at best. You may need to adjust the ride height, dial in more negative camber, roll the fenders, or a combination of these.

my 205/55-16 fronts (on 7x16 911 fuchs) still have a bit of fender rub even after rolling my front fenders (running continental extreme contact dw tires), couldn't imaging running my 225/50-16 rear tires up there without additional fender work. That said, I believe this to be the result of the 7x16 fuchs offset. Non-factory wheels may bring the tire in a bit and avoid the fender rubbing. This applies to a non-wide-body car too (86 carrera)
