New Tires - Need Assistance with sizing
 

Hello,

I purchased a 2010 R3 over a year ago and it's time for some new tires.
The previous owner put aftermarket rims on them.

Specs:
Emotion Kiwami
18x9.5 +38

I'm wondering what the best tire size is to purchase for my rx8.
Currently the front is a 235/45/18 and the back is 245/45/18 which i find a little strange.

Any help would be appreciated.
Thank you!

Would I be okay with 245/40/18 on all 4?
thank you

Should work OK..
It's one of the most common upgrade sizes
