Your thoughts on putting 225/50/16 tires on my 89

I found a good deal on a set of 4 225/50/16 tires. Is this a good size tire to use on Thunderbirds? Let me know your thoughts on this size tire.

Why? The factory size (for supercoupes) is 225/60/16. A 225/50/16 is 24.9" in diameter while a 225/60/16 is 26.6" in diameter. a difference of 6.7%. Your speedo would be off by 4 mph at 60 (it'd read 56 while you were going 60)

If you want 225's go with the 225/60's.

I just found this tire calculator and see that the 225/60/16 will be almost the same size as I have on the car. Oh well, so much for my great find on the 225/50's.

For 16's id recommend 235/60/16's. They give a little extra height to fill up the stock fenderwell and have a little bit more width too, and my speedo seems to still be dead on or at least it's close enough for government work...
