I have moved the springs in 3 inches with the shackles and hangers.What size tires can I safely run now with 7 inch stock wheels on my 69 dart?Thanks Kevin.
Did you mini tub it ? You cant go very wide on a 7" rim and if the wheel wells were stretch you did gain that much. Maybe another inch tops.
I know guys that run a 325-50-15 or 28X13.5 on a 15X10 rim with mini tubbed cars. Other wise in the stock wheel well you should be able to stuff a 275-60-15 in it at the most. I measured a 255-60-15 fitting perfect in the stock wheel wells on a 15X8 rim with 5" back spacing after moving the springs.
most tire shops wouldnt even mount a tire more than 8" wide on those rims. theyre kinda picky anymore, liability wise. im running 275-50-15s on 10" rims with a mini tub and relocated springs and a narrowed rearend. the work isnt that hard to do but it takes some planning and some $$$$, but the fat boys out back do look cool.
