I purchased an l3000dt about a year ago with r4 10-16.5 front and 420/70-24 rears. So that is not the correct size tires for the tractor, l3010, 4310 etc had them, and the ratios are off a bit from the factory ratio. So I am getting the correct ratio for that tractor to be .67(7-16, and 11.2-24). So I am thinking of putting 8-16 AG and rims on front(Rc 91) to go with the 420/70-24(rc 136). And maybe in the future putting 12.4-24(rc 135) on the current rims that are 12" wide. Anyone see any issues in doing this?
