First gen wheels?
Front Iroc rims are the same and the factory rims if I recall. The rears are wider. My biddy has a set on his 93 excab and been running them fine for years. He just complains about the cost of 16 inch tires.
also would anyone know if P245/50-R16 tires would fit on them or what size could I run without rubbing problems?

What size tire are you currently running? If you have 235's I would suggest something along the line of 255/60/R16 or 255/65/R16. Either of these will be very close to the same diameter of 235/75 or 70/R15. I "believe" the backspacing of the IROC rims are the same or very close to your stock rims so I don't think you'll have much, if any, of a rubbing problem.
Front and rears are both 8" wide. Rears have more backspacing so they'll sit in farther than the front on an S truck. 245/50/16's will be fine. 1st gens had smaller tires stock (same as truck size) than 2nd gen 2wd Blazers. I have a set for my 2nd gen Blazer but found I need one rear as the lip has a chunk missing.

You only rub at full lock when you're dropped anyways. It's only a minor problem when making sharp turns in a parking lot. I've had numerous dropped vehicles and it's never bothered me. Trying to get money to drop my Blazer now.
