I'm converting my 68 from drum to disc and the manufacturer recommends 15in wheels what size tires would you recommend to still have clearances thanks in advance!

One thing you may want to consider is the brake drum diameter. 13 inch tires and wheels take much less braking force then 15 inch due to the reciprocating weight. 9 inch drums associated with 13 inch wheels will get hot when braking a 15 inch wheels if the weight is greater.

Widths of the rims you're contemplating would help.....

I'd consider 15x7, with more than 4" backspace, and 215/70x15 all around. Maybe 215 or 205x60, if the 70s are too tall.

on stock rims 15X7 4.24BS 205's will fit easily, as will 215's
up front you *might* be able to squeak in 225's if you keep the profile(aspect ratio) low and don't lower the front end considerably. you *may* have to slightly trim the lower front corner of the fender for clearance.
out back, with most stock rear ends you're not going to have any problems until you get up to about 245. height isn't so much of a problem as the quarter panel being your limiting factor-- if you want to keep the tires tucked underneath.
here's a list of widths and more info that can be helpful on determining what widths you're working with.

if you've deviated from a stock set up, generally you can use that information to extrapolate the numbers that you would need to select a rim and backspacing. but it sounds like you're not doing anything too exotic, so if you pump the search feature with enough info you should be able to find the info you're looking for.
as an aside, i don't know what kit you're upgrading to, but some aftermarket kits don't play nice with all 15" rims-- reproduction rally wheels and cragars come to mind. so double check before you buy!

Ok, so, I've posted parts of this list a few times, normally in response to some of the really inaccurate charts and lists that are out there and posted too frequently. It's not my list, I sourced it from the internet but I can't remember where. Since the time I downloaded it several years ago...
