thats why i originally suggested 245 55 15's if you look up a couple posts and even said 50 would be too short
245/50/15 is NOT the right size. It will be a full 1" shorter than stock

245 55 15 or 245 50 15 we already went over this

RE: 87 GT tire question
you want to get 245/55/15 and your speedonmeter will be fine. The sidewall, radius, and circumferance are within tenths. Therefore your speedo will be correct.
the width difference
225/60/15= 8.86
245/55/15=9.65
Your answer
When your going 65 you will be going like 64.95 actually.

RE: 87 GT tire question
I think I solved this question in the first post
...if you hope to come close cause that's all you will do..quit worrying about being off a few mph on your speedo...dang[&:]the world won't come to an end!!..grab a set of pony rims = 16 inch and 245 50 16's like I said in the first post..you'll gain two things...1 you'll get rid of your gay 15 inch wheels and have a more sport look and your speedo will be very close = #2..done end of point!![sm=closed.gif]oh and it'll probably be cheaper than the odd sizes tires you seek if you can even find them
