And the folks with the newer "snowflake" 16" wheels too!

Additional Information Out of some discussion on the Facebook group, it was noted that on 500s where the wheel bolts would be covered by a wheel center cap (like below), there may instead be a traditional one-piece bolt only made of steel. In this case, it is likely you will not experience the sort...

I’ve previously gone over other subtle details of the wheel attachment method for the (modern) Fiat 500, including the use of wheel bolts, the locating studs, as well as the choice and a non-exhaustive history of the 4x98 bolt pattern. Another topic of interest, which I can offer some comments on f...

Why 4x98? Although I haven’t yet discovered specifically which was the first car to use 4x98, perhaps the strongest “blame” as to why it has survived so long can be cast upon these two: https://upload.wikimedia.org/wikipedia/commons/8/83/Fiat600.jpg https://upload.wikimedia.org/wikipedia/commons/a/...

Very through write up, but why 4x98? The metric system loves the nice even multiples of 100. Why wouldn't the engineers? That is a fantastic question! And I very much think the same about multiples of 100. At the moment I have not figured out or found a compelling design reason for this choice, but...

Rotor/Wheel Locating Pins – Why? You remember the point I made above with having to align the holes in the wheel with the holes in the hub when using wheel bolts? Now imagine you’re an assembly line operator and you have to do that on every single car down the line. Now imagine you’re on that line ...

Wheel Bolts vs. Wheel Studs I won't go into the extremely basic explanation of what wheel bolts or wheel studs look like, but rather the more technical aspects dealing with the comparison of bolts and studs. Overall, this really seems to be a matter of preference and perhaps historical practice and...

Not sure the precise best subsection to include this in because I don't know if we have a "general" tech area, but some discussion on the Farceberks lately prompted me to think of how to technically explain the seemingly weird interface of the wheels to the wheel hub of the 500 along with ...

Lol, looks just like my current daily setup only with white paint instead of "hyper black."

I will definetely vouch for the Indy 500s, for any interested parties, they are really good tires for summer road driving and moderate spirited driving.

Welcome! I think you're not terribly far away from me (Quad Cities).
