This is my first post on this forum. Just upgraded from a B8200 to a BX2670 and I had a question about tire psi since the tires are a LOT smaller than my B8200. I ran about 8psi front and 5psi in the rear on my B8200 but I think that might be way to loo on the BX especially when using the front loader. It has turf tires and I mow 5 kinda bumpy acres so like the extra cushion the low psi provides, I'll do a little work with the loader here and there. Anyone have advice on this? Thanks!
