Will it fit ? Going from 17x8 245/45 to 17x9 255/40
So the age old question. Will it fit?
Current set up. (No rubbing at all)
Wheels - 17x8 45offset - Enkei RPF1
Tire - 245/4/17 - ADVAN AD08R
Going to
Wheels - 17x9 40offset - Konig Hypergram (Only $188 each but 1.2lbs heavier than the Enkies)
Tire - 255/40/17
By my math the new set up will be in theory.... (This does not take into account the actual size difference of the brand of tire or the difference in tread width by mounting on wider rims).
Wheels (1" wider but offset going from 40 to 45)
+8mm inside
+18mm outside
Tires
+ 10mm wider
-5mm diameter (as 255/40 shorter than a 245/45)
Ans running Moton Club Sport suspension.
Or should I be "safe" and just go with 17x8.5 which would be only
+1mm inside
+11mm outside
Thoughts ?

I’m running 17x9 +40 wheels with 255/40r17 tires and the ride height is 13.5” from the fender to the center of the wheel. There are no issues whatsoever.
