235/60/15 on front of duster?

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.
