will 265/30/19 fit the rear sport packge wheel on a 05 coupe??
if it does. is there any drawbacks??

 

I'm running 245/275 on stock 19s and like it.

There was a pretty contentious thread a couple years ago on this... I've had no problems and am on my second set.

ITS NOT SAFE!!!! but can be done... what will you run in the front?

 

see what I mean

 

You would need to run a 225/35 up front to match the 265/30 in the back. Overall diameter is around an inch less than stock, front and rear, which will throw off your speedo but will not mess up the VDC and will increase the wheel gap.
