On the back I'm running 10x16 with 23 offset and a 3" spacer 225/50/16

So basically previous owner kept the stock tire size but went from stock 6x16/7x16 to 8x16/10x16 which is a pretty big gap!

What we tried is placing the 1.5" spacer on the rear and increased the tire size to 245/45/16. This will fit but a 2" spacer would be better.

On the front we can place the existing rears 225/50/16 and keep the 1.5" spacer most likely.

So I'm on the hunt for 2" hub centric spacer for rear and then new rear tires. May just get 4 new ones (thinking Toyo Proxes T1R) so that they match.
I agree that you are making the best of a bad situation w/ 225/50 & 245/45 x16, w/ around a 2" rear spacer(in lieu of 3").

It's still not ideal, the 245/45 is only spec'ed for a 9" wheel, you can use it on wider but it's not recommended.

Unfortunately the only wider non R 16 is a 255/50 that is over an inch taller than a 245/45 and will kill acceleration

The ultimate solution would be 17s w/ something like 235/40 & 255/40 or even 255/40 & 315/35

You really want to keep the rears under 25.5" od unless there are major motor and/or trans gearing changes, under 25 is even better
