Calculate values such as rolling circumference differences, speed deviations, changes in ground clearance, tire diameter, rim width, track width changes or the use of spacers for adjusting the offset (ET calculator) and find out which tires or wheels are best suited for your vehicle. You will also receive a helpful graphical representation.
On many Gigabyte boards of this era, you might find an ITE IT8620 or similar controller. The SIO is the "traffic cop" for basic functions: it monitors temperatures, controls fan speeds, and most importantly, handles the power sequencing logic. If your GA-H81M-S won't turn on, the schematic for the SIO is where you start looking.
Based on the motherboard's block diagram, the system is centered around the Intel LGA1150 socket and the Intel H81 Express Chipset CPU Interface

Note the difference in rolling circumference:
Rolling circumferences are generally approved in the range +1.5% und -2.5% g. Please check with the responsible inspector beforehand.
