I looked at my stock front rims and sure enough they have a different offset to the SS112's So part of the answer may be that the ITP wheels are NOT a direct replacement for the stock Suzuki rims. I have swapped the Swamplites on to the stock rims, and I will test ride soon to see if this has cured the problem.......
Most shops don't know F-all about different offsets or backspacing for aftermarket wheels. This also includes tire shops that sell aftermarket rims for auto/truck applications. The farther you deviate from the stock backspacing/offset the more problems you will have with vibration and handling. Backspacing is the measurement from the mounting face to the back of the wheel. Offset is the measurment of the difference from the center of the wheel the mounting surface. 0 offset means that the mounting face is exactly in the center of the rim. You can have the same backspacing on two different rims but with different offsets due to the rims having different widths. The aftermarket rims probably have less backspacing then your factory ones. This will amplify any vibrations and make steering harder. It will also increase wear on the front end components most notably the front wheel bearings! Hope this helps.
