Appliance wheel backspace, offset

Post by Linda »

Does anyone know the backspace and offset of the Appliance wheels listed on the WIKI? These are the common 14x 6 for the Roadster.
Thanks

I do not know, but you can figure this out yourself by measuring your wheel

If you want to measure your offset, it can be done with wheels on the car (much easier with the wheel off.

It is easiest if you have a small "L" square or two. You first need to measure the section width of the tire. The easiest way is take the two squares and make a "C" and slip it over the tire and then take your measurement. From tire rack, I looked up 175/70x14 at 6.7"(170.2mm) on 5" rim...They say to add .2" for .5" on rim width change....so you should get about 6.9"(175.2 mm) for a 5.5" rims..... Take a straight edge across the outside of the tire and measure down to the mounting face about 3" or 75mm ....might be easier on the rear.

Take 1/2 the section width and subtract the measurement to the mounting face. That will give you the offset. 175.2/2-75=12.6 or (.5")

EDIT: I measured the distance between the mounting flange and the drum (I had one off the car) and it's ~1/8" or 3 mm therefore if you measure to the drum, subtract 3 mm or 1/8" because your measurement is too large by that amount.

I'll see if I can do this with the wheel on the car.
Thanks
