Just Ordered

[Hellz]

the H2 will fit a 37 inch tire stock. there might be some rubbing, that it seems to vary from vehicle to vehicle. 2 identical h2s with same tires, one will rub, one wont.
So if you have any kind of a lift, you will be fine.

as for trimming the plastic. im sure it is going to let water in some areas, but kinda late to be asking that now isnt??

you could do the heatergun method.
find the rubbing spots and heat it up till it is pliable and form it so it stops rubbing. the spots that rubbed for me was the back part, very bottom.

here is the area you will most likely rub.
as you can see, i didnt trim mine far enough, and well.. things worked itself out.
