Sean and I both went with Michelin XPS Ribs.
I went with 225 and Sean got 235 size tires.
The 235's are rated higher since they are taller and wider than the 225.
The 245 tires is the same height as the 225 but is 1" wider if I remember right.
Also both went with Eagle Alloy wheels.
Do you have your axles flipped or trailer raised?
If not, the 245's will probably rub on the inside.
My 225's did on my stock height FS3000 I had a couple of years ago.
Hope this helps.
