235/60/15 on front of duster?

With these 15x8 rims with 4 inch of backspacing it looks like I might even have trouble fitting 225/60r15’s....If I cant even run those then I will sell these wheels and look at different options.

A 15x8" with 4" of backspace and BBP disks is a terrible wheel spec. The outside lip of that rim is like 1" further out than the 18x9's I run. Even a 15x8 with a 0 offset is 4.5" of backspace, and that's still terrible. With a 15x8" and a 4" backspace you'll be hard pressed to get anything to clear, even stretching a narrow tire on there. A 225/60/15 is the narrowest tire that should be mounted on a 15x8". You need a different rim up front.

They will work, just needs a little work.

Fenders: 68 Dart
Suspension: Stock rebuilt '74 with boxed LCA and "340" TBars and +73 BBP disks
Ride Height: 11" from level ground to the front K-member bolt.
Rims: Crager 10 D Window, 15x7 - 4.25 back space
Tires: Cooper Cobra GT - P235x60

The 4.25 back spacing will but the rim about 1/4" from the zerk fitting on the upper ball joint. Now the work part, you need to do the following:

Measure 1 3/8" forward from the current lower strut rod bolt hole. Make a mark and drill it out. Adjust the strut rod to the new position. This pushes out the lower front corner of the fender and depending on the car, it may be all that needs to be done.

Next mesasure 1/2" towards the front from the lower front corner of the fender. Make a mark.

Next measure from that same lower front corner, 1 1/2" upwards. Make a mark.

Now take a cut off wheel and connect the marks. Your tires will now clear and nobody will notice.

At this ride height you may need to take off the upper fender strut bar and gently bend the tab up or the tire will hit them.

A 15x7 with 4.25" of backspace is a stock spec BBP rim, so there shouldn't be any clearance issues.

Could you include a picture of your height measurement? Which K member bolt are we talking about? The K-member to front radiator support brace bolt or the forward K-member to frame rail bolt?
