Do I need new wheels with higher load rating tires?

[Macaclje]

I have a 2007 TM 2720. I'm planning to get the 14" Goodyear Endurance tires with the higher load rating. I was going to have them mounted on the original wheels, but I've read through the other tire/wheel topics here and there is some mention of making sure the wheels are able to handle the higher pressure. I'm not sure how to find that out. Is it marked on the wheel somewhere?
Thank you!
