Will Aftermarket 17x8 wheel at +48 to +50 with 235/40R17 tire (NC) fit a Mazda Miata NC (2006-2015 US model years)?

Q: Will Aftermarket 17x8 wheel at +48 to +50 with 235/40R17 tire (NC) fit a Mazda Miata NC (2006-2015 US model years)?

Yes, reportedly. A vendor names 235/40/17 as the largest tire in stock fenders and says +48 to +50 offsets get it under the stock lips with mild camber; a second vendor sells 17x8 +48 wheels for that tire. Expect possible plastic liner contact at full lock; for no liner rub the first vendor suggests 215/45/17 on a 45-50 mm 17x8.
