A popular replacement wheel choice is the ZR-1 style wheel that is made with the proper 38mm offset for the 84-87 C4's. This wheel is a 17x9.5 and you can mount a 275/40-17 tire. Use the same size tire and wheel on all 4 corners so that you can rotate the tires for longer tread life. The 275/40 tire has almost the same diameter and tread width as the 255/50-16 so you won't have any issues with the speedo or odometer.
You can get a 17x11 wheel and use a 315/35-17 tire but that size is getting harder to find. The "real" ZR-1 wheel has a 36mm offset and it will fit on the rear of the early cars. But you lose the ability to rotate tires.
A good wheel brand are those from AFS Wheels; they advertise of eBay so just do a search there for "AFS Corvette wheels" There are some other vendors that will have the same design too. I have two sets of AFS wheels; one set for autocross with Hoosier A6's and another set for track use with Nitto NT05's. Never had a problem with them and they really don't take a lot of wheel weights to balance.

I have an 85 with auto trans and 3.07 rear, with 275/40/17 all round on 9.5 inch wide rims. the speedo displays the same as my gps
so perfect. Chrome wheels look good, depending on the color of your vette.
You can get 88-96 wheels with adapters OR the correct offset wheels, they do have The A mold wheels with correct 84-87 offsets at corvette central.
