Personally, I see no downside in having extra weight carrying capacity. In my opinion, they are less likely to blow. If one does go flat, the remaining one that is temporarily carrying the full load will be less likely to also blow.
Note: You should never intentionally overload your rear axle.
Safe travels!

No downside other than availability and price. Sure, if one needs the added capacity, great. But based on your last statement, that's not likely unless one is actually overloading the "real" axle capacities (aka the 10-11klb range) of the vehicle.
And if the extra capacity is needed, barring some obscure tire clearance issue on the RV, there are other options that are of similar or same capacity and not an obscure Euro tire size (albeit not as obscure as years past with the amount of Sprinter type vans running around.
Overkill is fine, it's one person's own money vs peace of mind I suppose. Just pointing out the (not obvious to everyone) differences and costs/challenges for little to no real world gain.
