Personally, I don't think I would go with a tire that big, but it does tight as hell! I hope you don't have any issues like rubbing. Please keep us informed.
Yeah, the overall diameter is just over one inch bigger than the OEM 17s and tires. I haven't noticed any decrease in acceleration(the 2.0 isn't a monster anyways). The speedo, strictly going by the speed radars I've encounter so far, is pretty much spot on still. As for fuel economy and braking, the Enkeis are listed at 20.6lbs(without tires) while the OEM 17s are like 23lbs(without tires) so I'm hoping the lighter weight is a benefit in those areas.
In retrospect I probably should have gone with a 225/40 tire(probably will once I need new tires), but I've got about 1k miles on the new setup and no issues with rubbing(knock on wood). As for the mpg so far I'm only getting about 25mi/gal
, but that's mainly city miles and I've only got 2,500mi on the odo so hopefully it improves....
And to the question above about going wider than 235, I wouldn't, the 235/45s I'm running are pretty much flush. Going any wider would probably result in rubbing for sure.
