On the L3130, yes it’s 4x4 & hst and FEL, can I put r4 on front and leave r1 on back? Will it mess up the gear ratio or is it ok? Not sure any r4 are listed in my owners manual. What size is compatible to the 7.2-16 r1 on front now? Local tire dealer can get me 2 of the 7.2-16 new but there almost 200 bucks each. May just have to bite the bullet on that price unless could get r4 that’s compatible for similar money or a little more including rims for it. I like the way the r4 do on front of my mx5800 when using loader is why I ask this. Only one manufacturer still making that 7.2-16 according to the tire dealer is reason price so high. Guess supply and demand at play there
