2.5 years, 0 problems... But I have it relatively centered between the upper & lower bumpstops. I would suggest running little (if any) crank on your t-bars... Erik's right, the stress on your steering can be fierce.

Bigger t-bars don't place any less (or additional, for that matter) stress on your CV's - Doesn't do a thing... They simply hold your vehicle up easier & holds a set ride height without as much fuss.

Fwiw, it is possible to run 33x12.5's with just your t-bars cranked... Rubs a little, even with the body seam flattened & the mudflaps removed... Not too bad though. Ran that way for 2 years before throwing on the bl. I imagine 33x10.5's wouldn't do too bad, so long as they're on a wheel with less negative offset than the stock wheels.
