It depends... 13.6's were something of a compromise tire on MFWD's because many times the front did not lead sufficiently however... a change to 14.9's will put the front lead just slightly over the acceptable range. It should fall in the 1-5% range. Depending on the transfer box your tractor has... it will probably hit just under 1% with the 13.6's and just over 6% with the 14.9's. At least that's the numbers I get on my Ford... but the Case may use a different ratio. Another thing to consider is that many, if not all ZF transfer boxes were simple multiplate clutch setups rather than a dog clutch that was used by other manufacturers... and these multiplate setups always have ~some~ drag in them, even when released... so you're always going to have a considerable whine about it when going down the road... and that will be worse with larger fronts. So... you may want to consult the tire data book that's found on the tire manufacturer's website (for that exact tire) and then get the drive ratios and calculate what the lead is now and what it will be with a change before you decide.
I've been thinking about the same changeover on mine but I'm a little reluctant to buy 2 grand worth of Michelin rubber when I don't know how well it will work. I know a guy that has made this change and it works fine for him... BUT the tractor hardly ever sees asphalt.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
