I have a 1988 Cutlass Supreme with stock 14 inch wheels. I'm upgrading to 15x7's. I purchased a set of 442 Rally SSIII wheels and will have them mounted next week. What size lug nuts must I use? Can I reuse the stock lug nuts?

the nut size will not change, i'm sure those will use the same style acorn nut, if not got to the parts store and ask they''ll have what you need

I believe the wheel centers are actually the same for both 14 and 15 wheels, they just changed the outer barrel part of the rim , made the inner part deeper to accept the same wheel center section so your new wheels will not know the difference.

X2 The centers are the same for both 14 and 15" rallys. Just get tires that match the stock 14" diameter. Stock 442 is 215/65/15 which is a 26" diameter tire about 8.5" wide.
