Ok guys, you've went over this millions of times need some help. Getting different opinions from lots of people. What is the widest size tire I can put under my 87 mustang gt with a stock 15" turbine wheel? I want to keep the wheels, BC they are in great shape. Once I buy tires that's it no going back after I order them. It's a pain in the ars trying to send tires back.

The widest I've seen was 255/50-15, but they bulged out. I wouldn't go bigger than 245/50-15.
Agreed on that...

However, it is very difficult to find an H speed rated tire (130 MPH) in some of the larger sizes.
It took some wrangling to get a decent set of 225 60-15 H rated tires for my 89 Mustang. There are very few manufacturers that still make that tire.

You may say that you don't need a 130 MPH tire since you won't be driving that fast. The catch is that the H rated tires have stiffer construction and you can really tell a difference on in driving at speeds above 60 MPH. The rear end of the car feels wiggly on corners and banked turns. That went away when I took the tires back to Sam's and had them put the H rated tires on all 4 wheels.
