Question 1967 tire size and BS recommendation

I read through the sticky re the 67 tire sizes and am a little confused on what to purchase.

I am looking at purchasing some 15" convo pros and was wondering what width and BS to use? I have a 1967 RS SS with a 12 bolt.

The tires I will be running are 225/60 on the front and 255/60 on the rear.
I will be lowering the car around 3" on the rear and roughly 2.5" on the front.

Would an 8" rim with a 4.5" BS on the rear and 7" rim with 4.25" BS on the front be OK. Should I add some more backspace to bring the wheels in more as I am going to lower the car? Maybe another 1/2" ? More / less ?

The wheels I am looking at are below.

Thanks guys.

Re: 1967 tire size and BS recommendation

I just checked the centerline website and the 15" convo pros come in the following sizes.

15 x 7 - 3 3/8 BS
15 x 7.5 - 5 BS

15 x 8 - 4.5 BS
15 x 8.5 - 5 BS

So the wider rim looks like it would sit more inwards due to the larger BS.
Not sure about rubbing issues with the tire sizes given?

215/65/15 will fit on front. Sorry I forgot front backspace. 15x8-4,5 rear with 255 will fit fine. I think front is 3,5 bs

So the smaller backspace will still be OK even though I am dropping it quite a bit? 3 3/8 BS on front with 7" rim and 225/60/15 and 4.5 BS on rear with 8" rim with 255/60/15.

I ran what I posted above with a 2"drop front and 1.5 rear drop with no issues on steel rally wheels. 255 in rear is perfect with you drop. I'm sure someone else here will chime in

3" on your rear is to low.

225/60 fronts may be to wide at 9 section width.

Indeed the way to go. That's what I run but with a 215/65/15 on the front. Car is lowered and no rubbing except on a large dip in the road at speed I'll get the slightest scuff on the outside of the front tire from the top of the fender well. That is with 400 lb springs, I have 500 lb springs to swap in and I'm confident they will cure the slight scuff.

Thanks mate. I have 550 lb springs on the way. :-)

For the rears would it be worth going to the 8.5" wide rim with 5" back space?

The wheels I am looking at only come with a 3" 3/8' back space in a 7" wide rim. As yours have a bigger back space and rub on the bigger dips, I am guessing these would be worse. They do come in a 7.5" wide rim with a 5" back space. Would the larger back space fit the front OK?

I think they may rub on the inside when turning.

Can anyone confirm that a 7.5" rim on the front with 5" back space will be good or no good?

A 7" would be the way to go.
