I have one brand new Michelin LTX MS in the 215 size and 4 new in the 235. Would it jack up my ABS if I just bought another 215 and ran them in the front of my dually and ran the other new 235's in the rear? If it is a no go I will just buy two more 235's and just use the 215 as a spare but I would rather save $200 and not have to? There is approximately a 4% difference in cirmcumfrance between the two sizes.

The truck is in my signature!

long as your not a 4x4 you should be fine dont think it will jack with the abs

 

I figured I might as well try it first before spending any money so I just left the original Michelin 215's on the front and not buy any at first. I had the 235's installed on the rear and drove for about 100 miles both on city streets and the interstate and there where no issues whatsoever!

I just figured I would update this thread for anyone in the future. As long as you have only a Rear Wheel Drive there are no apparent problems running different sized tires (at least between the two sizes I have listed here)!

and you will get better fuel mileage with smaller tires on front as the truck will aways be going downhill...

 

LOL, you know I could actually feel the slope in the bottom seat cushion and was thinking I might need to put a couple of spacers under the front mounting points to tilt the cushion back a bit.
