I want to put vogue tires on my 2014 XJL. The problem is they only make them for the front 245 45 19 so I'm considering changing the rear rims to 19.9 like the ones in the front and going 245 45 19 all the way around.
Has anyone done this? Will the car look and preform ok?

 

If it were me i would not be buying wheels to suit a tyre, in fact the opposite, i would be looking at a XJ staggered set up on 20 inch wheels and fitting Michelin pilot sport
Your XJ will look a dam site better in this format and fill up the rear guards, and if you are driving a 5.0 SC it will help a long way to getting traction transfer to the road pavement, my 2c

 

, except for the Michelins unless the extra cost is worth it to you. For me, the Continental DWS-06 is a better choice and is less expensive. I've been very pleased with them.
