Trimming the tabs alone will give you ~4mm extra clearance which may be enough for the 305/30/18 18x10.5" ET40 to work that bentom2 and I have been talking about.
I don't have a choice unless I buy 4 more rims. I have the SM-10's now and the only size they have in 10.5 or 11" is the 19x11 ET44.

I did the math:

Front setup is the 18x10 ET33 with 12MM spacers and 265/35 A052's.

Tire Diameter=25.4" /Sec Width=10.6

Going to 275/35 NT-01 = 25.55 & SW 10.91" so almost identical diameter and .31" overall ....0.155" more inside and outside.

Rear setup now 18x10" E33 with 295/35's

Tire Diameter=26.2 with SW=11.8

Going to 19x11" ET44 with NT-01 305/30/19's

Diameter=26.26 (same) and SW=12.32 (0.48" more) or 0.24" inside and outside.

With the 44 vs 33ET's 33mm=1.30" 44mm=1.73" , So 0.43" more inboard.

So 0.07" further out with the rims and the tires would be 1/4" more.

I've got the camber shim kit and can take the tabs out and roll them also.

I don't want to add anymore Neg camber than needed in the rear. I'm at 2.0 right now...

Sounds really tight...
