View Full Version : 500e Wheel Offsets

Have searched countless hours on this, but does anyone know if the 500e uses the same wheel offsets (ET35) as on the other 500s? I know the fronts and rears are 5.5x15 and 6.5x15 respectively. I am taking the approach that anything could be different such as offsets/clearances/etc.

Welcome to the forum.

I do not know the answer to your question however someone here should be able to answer sometime soon.

Welcome to the forum. I've been checking but haven't found anything in my archives. The offset specs may be behind the center cap or somewhere on the backside of the wheel.

Thanks all. I'm sure it's cast on the inside of the wheels, but I don't have the car yet. ;) I am already scoping out something like the Abarth wheels (HOT) or maybe sticking with 15" as there's more selection of (no pun intended) sticky rubber in 205/50R15. Would really love to fit some 225/45R15 on there. Maybe even 6.5 front and rear. I guess I'll have to be patient until I get the car and check all the clearances!

I don't want to sound like a party pooper here, but...

The whole point of the 500e rim design is to make them as aerodynamically neutral as possible to conserve energy. Same goes for the low rolling resistance tires.

Adding wide sticky tires and trowing off balance the aerodynamic harmony may not be the best idea when you have an already limited range.

:) You assumed I care about range, and I don't. :)

I care about fun, and the more fun I can make this car, the more it will get driven.

All you say is true.

But I too would love some sticker tires and less plasticky rims. And if one is replacing the rims, why not go wider for even more traction.

Please continue to share what you do and try. I agree that sacrificing a bit of range for fun factor is worthwhile.

Slight wheel spin might be mitigated by more stickiness. (Or slower acceleration but what's the fun in that.)

I'm just getting used to cornering and suspect that's really the aspect to tackle, until someone hacks the firmware, allowing us to adjust the power response in the 45mph to 60mph range.

Will do! If all I wanted was a soulless commuter transportation appliance, I wouldn't have picked the 500e :)

If I can make this a blast to drive like other hot hatches, then the more I will enjoy it. The suspension is quite soft, so I think first things first, is to ditch the low-rolling resistance "skinny" tires. I don't think the suspension can properly handle 17" Abarth wheels and low-profile tires. The first thing I did with our Volt was put on some sticky rubber and tweak the suspension. I'm really tempted for R-compounds, but I think that will be overkill, and I will just opt for some RE-11As or Yoko AD08Rs as a good "compromise".

One of the guys at Fiat USA has a 500e and autocrosses the car and does well with it. He figures with a set of coilovers the car would really clean up.

Very cool. I'd be tempted to AX the little 500e, but that's about the only time I'd get range anxiety. It's got a 53%/47% F/R weight distribution and is very narrow, so I would imagine with some bigger/sticky tires and MUCH stiffer coilovers, it should do pretty well. LOL... with slaloms, you could practically go straight. :D This will be my commuter/grocery getter car, so I'm just looking to infuse some more grip as the first step.

I guess the coilovers could really help the body roll feeling when cornering. It's the tallest car I have ever owned (leased) and the height plus the roll has really given me pause a few times. Still getting used to it, understanding the steering, etc.

I should know but what is "FIAT USA"?

The front suspension is identical to the gas cars, except for the springs. The rear suspension is from the Abarth, minus the roll bar. I hated the excessive wheel clearance so I gambled and installed a set of take-off Abarth stock springs (there are plenty of them available here for cheap). With the extra weight of the 500e, the ride height now is about the same as an 1-2" lowered Abarth. It was necessary to trim about 1" off of both the front and rear bump stops otherwise the suspension travel is compromised. The stock electric springs are 13mm front and rear, and very tall. The stock Abarth rear springs are 12mm and about 1.5" shorter, and the stock Abarth front springs are 15mm and also about 1.5" shorter. This combo sets the car almost exactly level. Stock Abarth wheels will fit the car no problem.

Thanks very much for the nice technical post! You are talking my language. ;)

How is the handling on the Abarth springs? With 15mm F and 12mm R (for a front weight bias), do you feel there is understeer, especially without the rear Abarth bar?

Was surfing your posts. Your ride height looks PERFECT. :D

Not sure if I will do suspension mods (initially :) ) as I haven't decided between lease or buy. Good to know the Abarth 7" wide wheels and 205/40R17 will fit no problem. I wanna shoehorn 225s on there :) Not sure if there's space. I'm pretty anal that it really fits and doesn't stick out or rub. Was looking at aftermarket wheels, and here's my collection of "big" wheels for a normal 500:

8" ET 25
8" ET 20
7.5" ET 35
7.5" ET 30
7.5" ET 30
7.5" ET 30
7.5" ET 30
7.5" ET 20
7.5" ET 15

Those never say what the tire sizes are, though. Biggest I've seen documented is a 215/35R17 on a BBS 17x7.5" ET 30. Seems reasonable as there is not much inboard clearance. I think somebody was getting some rubbing on 215s.

Looking to lower the suspension and change out the wheels as well.

Would love to see pics of your lowered 500e!

If I recall correctly on my 500e, the offsets are the same front and rear, with the extra width on the rears on the outside. I would have no problem running matched, wider wheels on the 'e', particularily when you would be running lower aspect tires (40 or 35) anyway if you go to 16's or 17's. From what I can gather from various sources, one of which I met who actually did some development work on the 'e', the wider rear rims stretch the tires a bit more, effectively making the tire sidewalls stiffer, which helped minimize polar end swapping in sharp turning maneuvers at speed which can happen if the tire sidewalls deflect, which is more of a problem with the 'e' because of the heavier and more rearward weight bias due to the rear-mounted batteries.

I know this is an old thread, but I can tell you the front 5.5" wide wheels have an offset of 35mm and the rear 6.5" ones have a 28mm offset.
