I hate trying to compare other internet impressions, too many unknown variables. But if we stick to
@Cblaxx19's setup and Icon's site as saying 5.25 backspace on 18" wheel should fit with 34x12.5 tire, then something isn't right? His tire size is an inch narrower so should be clearing with 5.6 backspace stock wheels.
I sympathize here and appreciate early adopters for this reason. Maybe some clarity from Icon is needed if that's not what they're trying to convey should fit, or maybe understanding what tire they're basing the 12.5 section width on as it could be far narrower as
@FaKtor34 suggests?
