Tire Issue
Ok my question is simple and short, would having 2 different size tires on my 96 GT cause any major issues with the differential? I recently had a blow out on my driver side and had to throw one on there just to get around since it is my daily driver, I am running a 295/35/18 on the driver and a 285/35/18 on the passenger... I could see how maybe running a hire profile on one side would cause problems but they are both the same profile one is just a bit wider than the other, should I be ok or should I get the other 295 on the passenger? Any help would be appreciated.

The "profile" is a ratio (aka the aspect ratio), and is the ratio of the tread width to the sidewall height. So even though your tires have the same profile, they have different tread widths which makes the sidewall heights different.
The 295/35-18 has a loaded diameter of 25.35", the 285/35-18 has a loaded diameter of 25.08"; this is only a difference of a 1.07% so it's not a devastating unbalance. It's not enough to trigger the t/c or mess up the ABS (is you have same), however it will cause the LSD clutch packs to work and accelerate their wear to some extent.
I wouldn't drive 10k miles like that, but a couple hundred or less won't screw anything up.
