No. A +6 on a 9" wheel will give you 1/2" more poke (and 1/2" more backspace) than a +6 om an 8" wide wheel. As the centerline (and location of the hub) remains the same, the extra 1" in wheel width is divided equally on each side.
I didn't see it anywhere, but what rim are you running?Might depend on the tire design too? Some have more sidewall tread than other and that would make it appear wider.
I was balancing extreme flex and shock clearance with tire poke. If you are willing to relax or more one of those items, you can get by with much less. RIght now I've been playing with the SDi E-Clik shocks and they really need 4.75 to use full turning angle.
I knew I didn't want it like my YJ where 40% of the tire is outside the fender!
The front vantage point is not great, but the rear shows almost the entire tire tread being inside the fender? 38x12.50 Ridge Grappler.
