I have the wheel size from the website and I'm pretty sure it's a 4/110 lug pattern but I think I need the offset so I can get wheels as close to stock as possible? I read I think brute Force wheels fit and some other brands have the same size
All wheels have the size,width and offset cast or stamped into the back side..usually on a spoke like the pics show. The offset is usually metric which can be translated using many of the tools found on the web.
In this example, which is the rear of a ZForce, the wheel is a 14X8.0"..or we just care that it's 8"s wide:
And that the metric offset is +46.5 which is the amount from the center of that 8"s that the mounting surface is off set to the outside which increases the amount that goes inward:
Using a converter, you enter the width of the wheel, then the metric number. The converter then gives you a number in inches. That number is the inset or the first number of the common offset. In this case it is 6.33". So, 8"s minus that number will give you the other number you are looking for, the outset. From this we see that this wheel is a 6.33+1.67.
You will never find an aftermarket wheel with this offset but you will find something close like..6+2..or a little more outward and less inward like 5+3.
Now, take one front and one rear off and get those numbers off the wheel. Google "Offset Converters" and get your answers.
