My vote is just to replace both tires with the flat free type. Saves the hassle of when they go flat again. I did that on the wheelbarrow and don't regret it at all.
You may come to regret that yet.
Right now we are working on my house and have two wheelbarrows. Mine where I looked at a flat free tire, balked at the price and compromised on a slime-filled inner tube for about $15, and one that a contractor has with a flat-free tire several years old.
The barrow of choice for every worker is mine because it is much, much easier to push. For one trip of a few feet it doesn't matter, but for all-day use nothing beats a real pneumatic tire.
I suspect that the flat-free one do not age particularly well.
