Need help w/wheel sizing for 68 Coronet

[jerry]

I want to go with the wide steel rims and center caps. Can I go as large as 15x8 in front and 15x10 out back?
Thanks

Depends on the backspacing. I just put 15x8.5 with 3.75 backspace and 275/60 tires on the back of our 69 Bee, and I don't think I could have gone any wider with that backspace. To get 15x10 without any mods, you will need at least 4.5 - 5 backspace. I think it can work, but make sure you measure because it will be very close. As for the fronts, I think 15x8 will work with 4.5 backspace.

10 X 15 will work on the back with 5" back space.
A 275. 60 x 15 tire is the widest tire you can go with out having rubbing problems.

for the front, you can go definitely fit 8" wide rim wiht 4.5" bs.. u can use a 10" wide wheel in the back, use 5.5" bs as a starting point. you could probably tweak 5.25 could work too
