Your car weighs a lot more than a normal Focus. In addition to considering the effects of heavier GAWRs and the proper tire load index, you might also want to think about your electric steering assist.
From the Focus Electric Modifiers Guide
, section 1-4.
NOTICE: Do not install an off road, aggressive tread or incorrectly sized tire. Any of these may cause elevated stress to the steering system. This can cause the power steering system to overheat and shut off the power assist, which can affect the safety and performance of your vehicle.
