Oh I know it. The cost of the TIRE isnt so much the issue. Its the 5 rims that I already HAVE with a good back space. That is why Im looking so hard at the 15 in part of this equation. Dont wanna re buy a new set of rims if I already have em. Conversely... The BFG MT's are still in pretty good shape too and I may end up having to run those any way depending on the funds and save up for the 37's.
Unless someone want to buy my 35's!?

Actually, the cost of the intercos is surprisingly in expensive for the tire.
What I have found
TSL SSR 279.00
Irok 303.00
Trxus 282.00
That is per tire of course.
Its just a matter of deciding is all. Not a life threatening issue. I do have the 35's that I can wheel with like I said. I dont actaully NEED the 37's, but I sure do WANT em to fill that big ass chop job I did on the rear 1/4.
