I can get a really good deal on a set of Michelin Super Sports but was wondering if they will fit and will be ok for my F

FRONT SIZE
225/35R19 (88Y) XL
REAR SIZE
265/30ZR19 (93Y) XL


The tire size and load rating is slightly different in both cases . will this setup be safe?

 

I would not run those tires. They are significantly smaller diameter than the stock sizes which means rim damage is more likely if you hit a hole in the road.
