K specs show M6040 ft tire size (4wd) as 12.4x24. the stock fronts on my 7040 are 9.5x24. Can I switch to the 12.4x24 on fronts (AG) w/o damage to: 1) ft differential/ axle 2) 4wd 3) limited slip 4) warranty? will they fit on existing wheels? could use more traction w/fels & wet conditions.thanks bb
