Blue dot of Rims

[Wangtang408]

Hey Guys, I have noticed that I have blue dots on my stock 19" sports wheels, I removed the dots on my 19's and don't have a pic but I just saw these 350Z wheels and they have that blue dot as well. Is this normal, anybody else out there have these blue dots?

Yes I have them too - one dot on each wheel in the exact same location. Dunno why.

It appears to be paint and I never tried removing them because I have chrome wheels and I feard it would leave a blemish on the finish of the chrome.

Thanks for confirming Larz.

From the web:

"Apparently every tire, no matter how good or expensive, is slightly out of round and has small variations in sidewall stiffness. And every wheel is, likewise, out-of-round by a small amount. What they try to do is match the hard spot/high spot in the tire with the low spot on the wheel. The low spot on the wheel is where the blue spot is. Then I noticed the blue spot on the wheel is directly opposite a red spot on the tire - obviously where the high/hard spot on the tire is."

Another Mystery solved.

wingFeather, just noticed in your profile car list that you got your hand on the highly sought after Nissan Cube. Congrats on the purchase. That car is talked of highly in this forum!

I was going to post something similar, but you got to it first. Thanks!

Yes, this is the reason, and it is good to get any tire replacement person to follow this ... it allows smaller weights to be used to do the final balance.

Not a major issue. Another approach is to line up the tire dots with the valve location ...

Yup! I have been living here since 1989.

Where did you buy your M from? The dealer (if so, was it Frontier Infiniti)? Or some other place?

Nah bro, flew down to Palm Spring to get my M, ain't too many Ms around here, matter of fact Beshoff Infiniti (down the block from my house) send me an email offering 110% trade in due to high demands. No way Jose, only had my M since March 2013. Riding it til the wheels fall off!! LOL
