And 55psi isn't a big deal. Search Google for "Factor of Safety" - it's one of the few engineering terms that's to the point in what it is I've been having trouble finding the FoS for modern tires, but bias ply tires were designed with an FoS between 4 and 11 with optimal FoS at 7. That's 7 times what's rated on the side. And, no doubt, modern tires at least meet this criteria. I'm not worried

Plus, added benefit of less tendency to hydroplane (something important to me given my location).
