Backspacing question?

[TooT]

I'm gonna order 15x10's for the back but i need the backspacing so they wont stick way out of the bed and look goofy. the tires are 295-75's. i wanna keep them nicely tucked within the bed oh and about the front....would 15x7's look silly on the front? or how about 15x8's? help me out folks!

I am pretty sure my Cragar's are 4.25" backspacing and they are 15X10's.
Here's the best shot that will give you a profile of that.
Someone will be able to verify that is the correct backspacing though - it is standard.

I measured some 15x10s on the back of my truck (Havent bought the correct ones yets). For the WIDEST tires I could find that would fit under the bed, I came up with 5 1/2 inches of backspacing to tuck the wheel under the bed, but not mess up the look (track width). For the front I came up with 15x7s with 3 1/2 inches OR 15x8 with 4 1/2 inches, depending on your preferences.

Heres a link to the tires Im gonna use, and the mock up wheels I was using.

Those look good but they are still sticking out a lil more than i want them to. maybe a little more like jay said would be perfect. here are the tires with 8" ralleys thats on it now. 295-75's

Oh and here is the video of me breaking those new tires in.

If you can get your hands on a set of 15x10s, bolt them up and start measuring. Those tires that I want are actually 14 inches wide at the bulge. So I measured where the bulge would be in relation to the body, and that how I got my measurements.

RatRod67 has a sweet setup on his truck... measurements and #s are here

Couple of more pics I found...

I put some Impala SS wheels on which are 17x8.5 with 5.125 backspace. The tire I have on the rim is close to the inside of the inner wheelwell on a fleetside. I don't think I would go any more than that...they might rub around corners. If you do get them on post some pics...

So 5.00 backspacing would be about perfect? those pics are better orange, thanks!

I have 15X10 on my 72. 5 inch backspacing.

5 inch back spacing seems to be about right , but with the factory panard bar ( coil spring)the rear axle may not be centered between the wheel wells, so check that first.

I didn't see a year mentioned, but the 67-69 rears are about 3/4 inch narrower on each side than the 71-72 rears, 70 could be either. That 3/4 inch can be made up in the offset if you have an earlier rear.

It's a 69 shortbed.
