    Largest tire for a Sierra Trail Boss?

    I am looking at buying one, but from reading here the tires are small. It looks like the brochure Mike posted it comes with 16" tires? Am I reading that correct? Is there enough room to step up to say a 18" tire? Also is the rim 6" or 8"? Hard to read what size it stated it came with.
    Thanks in advance.

    The stock tires on a Sierra Trail Boss are 18".

    Original tires were 18x9.50x8. With the original Tera grip tread, that leaves you 3 inches between tires, and about 2 1/2 inches between top of tire and tub. I've seen pics of one with what I am sure are larger tires. I think you could probably get 19s on without any troubles, but would be careful before going 20.
    It's all just nuts and bolts.
