So my Marauder is coming due for tires soon, still have tread but the shopping has started.

Current tire size is 255/45/18's up front and 265/50/18 in the rear.

I cannot a rear tire in that size. I was aware that Nitto quit making the 555 in that size, but I cannot find any tires in that size.

What size tires are folks running on stock wheels?
