Looking closely at your Photobucket pics, it's clear you have custom made one piece drop center rims up front. I didn't look that closely before my first reply, so your 4.5" statement is no doubt correct. I still think the 6.00" is the narrowest you'll want to go, but would suggest you check other sellers to ask the question. Places like Universal Tire, M.E. Miller, and Lucas Tire may be able to give an answer. Stu
