All i need to know for Cragars on a 73??

[Kramersdodge]

I am planning on bumping up to 15" Cragar SS direct bolt wheels for my '73 Charger. I have had issues figuring out what size tire I can fit because of the limited backspacing. I really don't want to have to custom order, since that doubles the cost per wheel. Available is 15x7 with 4" BS and 15x8 with 4.25" BS.

Anyone have wheels similar in size to these? Any idea of the largest tire I can slap on these without clearance or rubbing issues? I have read a member here, 68RT4me had same size wheels but the BS was 4.25 and 4.50, respectively. I amd WAY too paranoid to order my wheels until I know what im getting myself into!

Any help would be greatly appreciated! Thanks in advance!

I used to run 15x8.5 centerlines with a 4-7/8 backspace with 275/60/15 and it was a perfectly centered fit in the wheel well with no rubbing. I think your set up will be fine.

If you really are paranoid, get a level, straight edge, and measuring tape, take the wheel off and measure for yourself! Just remember that a 15x8 wheel is actually about 9 inches wide. Account for the sidewall bulge by checking specs from Tirerack.com

I had Craggars SS unilug, on my 73 for several years and 30K. miles . No problems except the pain of unilugs. Look good. Not close to rubbing,

275/60-15 BFGs  on 8x15 rear
Back spacing was what ever Jegs sells that is about in the center of the wheel. I should have written it down , what you mentioned sounds about right. I still have them, if you live in central Ohio drive over and try them on.
