Stock Tire Sizes

[GhettoPop]

I'm looking to put new tires on my stock 90 GT wheels, the original tire size is 225/60 15. Here are some options I am considering:

BF Goodrich Comp T/A ZR - 225/60 15
BF Goodrich Radial T/A - 225/60 15
Mickey Thompson Indy Profile F70-15 or G70-15

OK here are my questions. First off, which size mickey's will fit my stock rims? Also, since the stock size is 225/60 15, can I simply up it to 245/50 15 w/o any problems? If so, how much bigger can I go w/o running into problems? I'm not looking to buy different size rims, fabricate my wheel wells, etc, I want to keep the stock wheels.

Also, does anyone run these tires on their ride, if so, how do you like them? I'm a HUGE fan of white lettering, so if anyone has comments on these tires, or any other possibilities, I'd really appreciate it. Thanks.
