If you are lowered or going to lower, the 235s are the safe choice. 245s may rub in certain situations, if your car is lowered.I know this has been asked a million times...
I'm looking into Neuspeed RSe11Rs, 18x8.5. Trying to decide between 235/40/18 and 245/40/18 tires. Does anyone have any thoughts? I'm leaning towards 245.
I'm going with PS4S tires for what it's worth.
No plans to lower, then definitely go for the 245s. The taller sidewalls will fill up more of the wheel gap and give a slightly better ride, as well as look fatter on the wheels.
