Wheel Spacers : What Size?

Monday October 18, 2010

Ok, so this our round 2 post on wheel spacers. About a month back we did a blog post with some basic info on Ichiba & Kics Wheel Spacers. After that post we’ve been getting a lot of questions about sizing and how to choose the correct wheel spacers for specific applications. This follow up post will help you choose the correct size wheel spacers.

The biggest question we get is “what size wheel spacer will give me a flush stance”? Now a flush stance is relative to personal perception, so what we may think is flush may not be flush to you… with that said this is a very hard question to answer. Take a look at the picture below and use this as a measuring guide to help you get an idea of what you’ll need.

The widest point of your tire and wheel combination is usually the tire sidewall. Using a ruler with the straight edge flush to the sidewall of the tire, measure the gap between the tire to the inside lip of the fender. This will help you determine what size spacer you would like. Also keep in mind that stretching a narrower tire on a wider rim and/or rolling the inner fender lip will allow you to get A LOT more aggressive with how large of a spacer you can use.

Another question we get is how does mm calculate into inches, so here are the popular spacer choices with the corresponding size in inches next to it.

5mm = 0.1969 inches
10mm = 0.3937 inches
15mm = 0.5906 inches
20mm = 0.7874 inches
25mm = 0.9843 inches
30mm = 1.1811 inches

Lastly is finding out your bolt pattern, thread, & center bore size. The best way to do this is to check out www.BoltPatternGuide.com. Now this guide is not a complete list and leaves off a lot of newer cars so if you are having trouble finding your specific vehicle please contact us for assistance on this one.

    I have a 2005 Nissan Xterra that had 265/65 R16 tires that are stock. I have put a 3′ inch leveling suspension kit on it where it is 3′inches in front and with shackles and Pro Comp shocks on the rear giving it barely 3′ inches also. I replaced the tires with new Dick Cepecks that are 285/75 R16 which is basically a 33 inch tire with 11.2 width (wanted more thought it was 12.5). I have a 6×4.5 bolt pattern and a 6×114.3 hubcentric with centerbore at 66.1. I have no gap at all between outside of the tires and fender as they meet flush. I am rubbing when I turn my tires hard just backing up or turning out of a parking stall. Can I run 1.5′ or 2′ inch spacers all around? What is the advantage to running different sizes up front and at the rear and why? Please tell me what to run up front and in rear. Thank you.
