Hello folks. Have a 755 mfwd backhoe/loader with turf tires sized 33x12.50-15 rears, 23x8.50-12 fronts which are cracking with age. Need to replace but would like to find a tire with just a little more grip than a turf tire without changing rims. One observation that I have made is that the tire size spec'd for the 755 is 31x12.50-15. The tires on the unit now are spec'd for the 855. Not sure which size to go with. Any recommendations or comments would certainly be appreciated.
