I have a 2008 ford p71 and wanna get new new tires?

I was looking at the primewell sport ps860 but their 235/60/r15 they can onto the car with no problems but the actual crown vic steel wheel will not support that tire is another white letter tire out there i can purchased
My last choice is getting chevy rims with 9c1 hubcaps and getting my primewell tire please help thanks

Added (1). The crown vic tire size is 235-55-17 with 17x7.5 rim

The Primewell Sport PS860 is a POS tire. Cheap Chinese junk. For about the same cash you can get a much better quality tire such as the Continental TrueContact or the General AltiMAX RT43 for just a little over $100 or so a tire.
