Will these tires work for my Mitsubishi?
IT WELL COME WITH INSTRUCTIONS AND PICTURES TO SHOW HOW TO INSTALL IT
They will physically fit, but your current tyres have a Z speed rating You need to check if your car needs that, and I suspect it does. The tyre fitter should know the answer and it will also be in the owners handbook.
I did a quick search and found the original tires were 215/50/17 but multiple sizes can fit the same vehicle. The correct size tires can be found on a label in the drivers side door jamb.
