Yes Billsta the 245/75-16's do fit, even with a little bit of room for expansion, but they are as big as you can go. Any taller wont fit in the wheel well, any wider the cover wont close flat. The 265/75-16's are an inch taller and about 20mill wider l think, so to big for the wheel well but a size l would of liked if it was standard.
Going from 245/70's to the 245/75's while it's only an inch taller they do look a little thinner, but i'll get use to it.( razer blades should only live on something else).
