Your tire width and wheel backspacing?...pics?

Trying to decide what width tire to go with for my 2010 JKU. I know I'm gonna take a hit on MPG...whatever. I don't want to replace with pocket style flares. I'm going to have 4.5" backspacing on my wheels and trying to figure out how far the tire will stick out from the fender. I know it'll be illegal in MD if it sticks out at all. I'm cool with it sticking out a little.

Basically, what I'm looking for is people with stock fenders and a pic from the back so I can see how far they stick out. What width tire and backspacing of the wheel would be helpful (and you can throw in your lift and tire type too if you like).

I appreciate everyone's help.

Thanks for the pic. Love the duratracs (that's what I'm going with). Think I'm looking to go wider than 10.5 though.

Yes the 33's are about another inch wider. Just want to make sure that you are aware that it will make your ride more sluggish. Even from going from stock 32's to these I notice a small drop in power and about a 1.5 mpg reduction.

Richie do you have a shot of your Jeep from the side?

Anyone know how far a 12.5" wide tire and 4.5" backspacing wheel would stick out of a stock fender?

I would say 1-2 inches. My 10.5 wide ones are pretty much flush with the edge.

Cool. That's basically what I was looking for. Thanks.

I'd guess a little more, just because of your planned backspacing.

I effectively have 4.5" bs (6" bs minus 1.5" spacer) using the standard BFGs (10"), and would estimate the tires stick out about 1". So, if I were to add 1.25" of width to each side (for a total of 2.5" more width) that would be about 2.25" outside of the fender.

Just a guess though.

I see. I think I'm gonna go with 305/70R16 duratracs. Tire calculators says that's 32.8" tall and 12" wide, but Goodyear's website says it's 33.1" tall and 12.2" wide. Anyone know which one is more accurate?

This might help.
