Not wanting to assume( you know), is the Fiat 500 bolt pattern 4 x 98mm? Thanks.

Hi fiatdad, welcome to the forum! Yes, the 500's bolt pattern is 4x98.

Hi, Thanks. That was fast.

Are we absolutely sure that the bolt pattern didn't get changed to 4x100mm? I'd be absolutely stunned if they gave us a 98mm bolt pattern - considering the fact that to my knowledge there isn't a single other car on the market here with that configuration... I guess I'd like to know what your source is; I realize the euro spec does use the 98. Might have to find some "wobbly bolts" I guess.

Sorry to sound contrarian but...

Are you sure? If you look at the photograph at the top of the forum site, the US fiat looks to use a 5 bolt pattern on the Sport model in any event.

Now I could be wrong but it looks that way in the photo.

Looking at this photo below all the stock 500 wheels, including the sport wheels, have a emblem cover over the wheel nuts:

The only photo I have seen showing the bolt pattern is from the Mopar 500 at the Detroit Auto Show

Oh, you're right, never mind then.

I should've known that.

I don't know why Fiat would change the bolt pattern just for the U.S. market.

I may be wrong but I think the 4 x 98 has been a Fiat standard for decades, think the 850, 128, X1/9 and other used it (of course in 13" and 14" versions). Did they ever use any other? 4 x 100 does sound familiar, was that used on Alfa's?

Jim M. is right about the 4 x 98 being a Fiat "standard". Does anyone know if the 500 uses lug bolts or studs? I used to hate those lug bolts on the X1/9. I changed them to studs on my race cars.
