if you had the right bsp maybe, im just curious why an 11" wide rim?? whats wrong with a 10"..most tires would look better on a 10"..i have 17x7's up front and 17x8's in the back and i cant tell the difference unless i really compare the lips of the rims..
just asking

Call me mid next week, and you can come by and measure the inners free space, and outers.
I have TT II's 8" wide # 505-7863 rear which are 4 .75" back, which makes front to lip 3.25" 4.75+3.25=8"
Tire is 275 40 17. With 3.25" front the tire is close to the lip, but works.

I measure I can still get 1 .5" to the leafs and inner wheel well. So add 1.5" to my 4.75 back, and you have 6.25 BS. But TT II's only come 6.5 back, 3" front with a 9.5 rim.

This is .250" too far back, and will hit the spring, and inner well. Easy, then just add .250 spacer to move the rim out from the leaf and you now have moved the 6.5 to be actually 6.25" back.
Keep in mind, the 9.5 originally had 3" front, but you have added .250" with that spacer, so you are now 3.25" front, just like mine, almost at the outter lip.

My 275 tire section width is 10.9", with 10.2 to the ground.
a 295 is 11.4 section width, with 10.5 to the ground.
No matter how you measure, the max tire section width you can fit without tubs, moving the leafs is about 11.2 comfortable, as you only have max 12" in the tub area.
For me, I am going to stick with the 8", and maybe consider a set of MT Street, or BFG drag radials for summer non rain use.
These measurements get way too close for hard cornering with sidewall flex with a 9.5 rim.
The BFG-G Force I use have side walls so hard, it took 3 guys, and 120 PSI to mount them, the side walls are like solid steel, and do NOT flex. I would not try a soft sidewall with a wide rim with literally no extra clearance.
Give me a call on this issue, its not that easy a choice.
