Potential mild pinch weld rubbing. My friend had 17x9 MM 951 with 4.5" b.s. with BFG MT KM 35x12.5x17 on a PC stg1 lift. Mild rubbing at the pinch weld ... small amount of trimming, but he didn't grind his steering stops down, so perhaps he would have needed more at the weld.amerrill130 said:

Me personally, I would stay away from anything with a negative offset! JMHO 
In general your opinion has merit, but maybe you can explain why ... there are some applications/reasons where a negative offset or at least a smaller backspacing can be a better option.yscty said:Me personally, I would stay away from anything with a negative offset! JMHO
Some advantages to having a more deep dish wheel ...
First, with negative offsets, for example, the new and popular American Racing Teflon coated Thug, (and its fraternal twin, the chrome Cannon), are offered in a positive offset 17"x8.5" but someone on here had to use wheel spacers! Calipers were rubbing because of the rim design. And just the other night someone else had the same issue with an 18 of a different brand! So cut out the pinch weld using Kartman's method or grind the brake calipers? ... Caliper grinding probably isn't a big deal, but I know that the pinch weld mod for sure isn't bad, and your Titan will not break in half.
Second, with a positive offset, if you have a wide tire like a Nitto Mud Grappler, 13.2" wide on a 10" rim in a 35x12.5x17, or 12.8" on a 9" rim. [Or the Toyo MT at 0.1 inch narrower], you could be in trouble with spindle rubbing, especially if you have a 2wd and have the PRG CST 4" spindle pkg. The 4.75" b.s. that CST recommends for the 4" spindle makes sense for very wide tires and rims.
Third, the stability you get with a wider track matters ... especially for disco/poser lifts of greater than 3 to 4.5 inches. Lol Best way to get a wider track w/o a longer axle shaft.
Fourth, it just looks better ... JMHO. If you look at my sig pic. and can visualize my wheels sticking out an inch to an inch and a half more, wouldn't it look better? Even with the same skinny 285 tires, it would look better. It's just the way it is.
When I go after market rims I will likely go for an 8.5" w/4.5" b.s. or a 9" w/5" b.s. ... which are a -6mm offset, or a 0mm offset respectively. Both will stick out and rub the same amount.
