Disadvantages of "going up in size": The tires may not fit if you go up too big
Advantages of "going up in size": You gain increased load rating. That means greater "safety margins" as the tires age. Typically ST tires "degrade" about 10% of their capacity per year, so the more "initial reserve" you have, the longer the tires will "stay above the actual axle weight". At a price of $1 per tire ($4 total) between 205 75R14 LRD and 215 75R14 LRD tires, the decision (at least for me) is clear. YMMV
