2007 Silverado Classic Steering problems

HI

I have created an issue and have no idea what to do to fix it. My Silverado HD2500 4x2 (6.0L, auto) came with 245x75x16 tires on 6.5" wide wheels. At 6700 miles, I changed to Hummer H2 chrome wheels (17x8.5) and put on Toyo A/T tires, size 265x70x17. It all fit perfect and looks awsome.

The wheels have a negative offset causing the wheels to stick out farther than the factory stock wheels, hence the turning radius is different.

Unfortunately, when I turn a corner, the steering wheel does not return to center. The steering feels heavy. Is this a function of the bigger tires (I have done this many many times on Fords)? Or, the offset difference on the wheels?

Is there anything I can do (outside of changing back to the 16" stockers) to correct this problem OR do I just live with it? How much damage might this due to my steering system?

I did crank up the tire PSI to 65 in the front and 50 in the rear. It did help some, but not much. Also, I did NOT mess with cranking up the torsion bars, and did not change the alignment.


Thanks in advance for your help.

Dave the dummy.

Larger tires, and rims can cause a few issues, ABS can be affected as well as vehicle speed sensor, and as you found out, steering linkages and gears. Put originals back on it, most if not all tire shops won't increase tire sizes aby more. If they know what there doing!

The bigger tires with the offset wheels will also cause excessive stress on the wheel bearings. The wheel alignment is also greatly affected.
