It is cool. What is NOT cool is the fact that so many members will ask

What will fit better?

instead of using a calculator and figuring it out.

Nice links, but one should also know how to calculate tire heights with this:



I don't use an online tire size calculator.

Reported rim width (mm) X tire aspect ratio X 2 (top and bottom sidewall) X (1"/25.4mm) plus wheel height equals total wheel/tire height.

285 * .3 * 2 / 25.4 + 18 = 24.7" tall

Easy to do without the internetz, like when you're at the tire shop and they are trying to tell you that a VDC-equipped car will work with a 275/30/19 rear tire and your 255/35/19 front tires.

Default Need to find replacement rim(s)

When I bought my Z it had 20x9's on Front and 20X10.5's on the rear. I have trashed one of the front rims and cannot find a replacement for it (AXIS Shine Gunmetal). Pic is attached. What I really want to do is replace this rim but it has been discontinued and the company has since gone out of business. Does anybody know where I can find this rim? If not I will have to buy rims all around in which case I will need to know the proper offset for the new rims. With a lowered Z, what would the proper offset be for 20" staggered rims?

The damaged rim
