the 225 will have a mild to no stretch at all on the 8.5. i got a 8 in. width and 225 is too fat for my taste. also, the 48 offset will somewhat set the wheel flush to the fender or slightly poke out. i run a spacer on my car for the front wheels which are 45mm. corrected, offset is about 42-43, and it sticks out a little.
