Hey guys, im new to these forums and new to being a mustang owner as well, just bought a 68 last week. Im really excited, i got a great deal.

Anyways the first thing i want to do to it is get some new tires and wheels, because i noticed a rather substantial crack in one of the tires rubber and dont wanna risk it.

I was thinking a width of about 250-265 in the rear and 210-220 in the front. What im wondering is: what kinda of space do i have to work with on these 68s? Right now it has a pretty ****ty set of AR 14" rims with 205/70/14 tires on them and it seems i have plenty of space in the rear bit it looks a little cramped up front.

Right now i plan on putting some AR 17" rims all around but im not sure what do do about back spacing, because i really dont wanna order rims and then have them sticking out too far past the fender. Does anyone know anything about what type of backspacing would be ideal for a 265ish rear tire and 215ish front?

Thanks in advance for any advice you have.

get a wheel with a ~4.5" backspacing and youll be good.

if the wheels have a bigger BS, then you need spacers. i have 05 bullits on my stang and i need 2" spacers in front and 1" in back.

but AR or vintage wheel works offers custom backspacing. i myself am gonna get the vitnage 45's, 17x8. they need no spacers cause they have a bigger lip due to the correct backspacing.

this will help you a lot

Hey thanks, i thought i read somewhere that someone had done a wheel chart. Yeah i do like those Vintage 45s. I can't decide between AR's Torq-Thrust or the Vintage 45s...they look pretty similar. Is there much of a difference between them?

Would i have to cut out the wheel wells if i put a 275 tire in the back of my 68?

Theyshould barely fit with a 17x9 wheel with the proper backspacing.

Nice little chart! Just saved it.. thanks

jonward786

Yeah really handy chart there, thanks man.

Starfury

np It's an old chart, and the VMF has it posted on their FAQ section.

Dodgestang's charts are much more in-depth and cover various suspension mods, but I like this chart for basic guesswork.

I've got 17x7 front 17x8 rear Vintage 45s on my 68 coupe. not sure if yours is cp or fb...
Here is a pic just for reference since you said you are considering these rims.

Wow man, that looks amazing...my 68 is a similar color and i was skeptical that the gray would look good, but it looks awesome on yours. What width tire you have on there?
