Do Bigger Tyres Make That Much Difference

Sorry, I cannot comment on the stud length.

Guys, this is the correct method to measure Wheel Offset... Stoney your correct but I though this might make it easier to visualise...

The wheel's offset is the distance from its hub mounting surface to the centerline of the wheel. To determine wheel offset:
Position the wheel on a flat surface and measure its overall width.
Divide the overall width by two, then subtract this result from the backspace value.

Offset = Backspace - (Rim Width ÷ 2)

The offset of a wheel can be one of the following three settings:

Zero offset:
The hub mounting surface is even with the centerline of the wheel.

Positive offset:
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front-wheel drive cars.

Negative offset:
The hub mounting surface is toward the back or brake side of the wheel's centerline. "Deep dish" wheels are typically negative offset.

Note, don't get confused with rim width as stamped on your rim and your width of wheel measurement when calculating offset...Cheers TOMUCH
