MuuMuu101's 68 Dart, A Learning Process...

But I kind of want to go to a wider tire. A 265/35/18 seems like it would have worked with an extra +3-4 mm spacer on top of my +5mm spacer. But almost approaching half an inch, I think I'd want to install longer wheel studs.

^^^^^^^ Must do!!!!!!!!!!^^^^^^^^^^
And, when you get out that far, you want hub-centric spacers so you don't get a wobble.
