Giulietta alloys on 159

There's a simple question, will 2010 Giulietta alloy wheels fit on 159?

I've compared both specs and there most probably will be a difference in the backspacing, assuming that ET is 41 on both platforms.

Any suggestions? Will they fit on 159, 1.9JTDm?

My understanding is that the PCD is different - the 159 has common PCD with Saabs and Vauxhall/Opel and the Fiat Chroma, but not with anything else from Fiat Group.

IIRC the Giulietta shares the same fitment as the 159/brera/spider

You may be correct Cobra - 159 is 5 x 110 PCD with a 65mm centre bore which is the GM standard hub.

Traditional Fiat is 5 x 108

In July someone reported seeing a Dutch Giulietta with 159Ti wheels - who will be the first to try the swap?

We will pick-up the Giulietta on Thursday so I'll try it on the weekend

Except the fact, that Giulietta uses 18x7.5", but 159 uses 18x8" wheels. Then there will be 0.5" (6mm) difference in backspacing and wheels could touch brake calipers on 2.4JTDm models.

I've got an after-market 18x7.5'' on my 159 and its fine

The calipers on the V6 & 2.4 JTD are bigger so 7.5 probably wouldn't fit

Isn't the TI a little different to the lusso?...

I have just bought a lusso and I want to see if the 18" cloverleaf will fit mine
And I also want to see them on a lusso 150 2.4

What about the rolling circumference difference of the standard tyres of 4%. Is that considered an issue when swapping wheels between Giulietta and 159.
I'm considering putting my 159 wheels on a Giulietta. Should a change tyres to prevnet the 4% difference or just ignore it?

Just bringin back this old thread. I'm curious to hear if someone has an answer to the above question?

I just switched to a 159 2.0 jtdm. Loving it so far. Unfortunately I had to let my Giulietta go. So sad to see it left there at the dealer's parking lot
But the 159 is a beautiful thing

I kept my winter wheels. These are original Giulietta 16" alloys with winter tires. Will these fit my 159 and should I worry about the slightly smaller tire?

I dont think 16'' wheels will fit over 330mm brakes but why dont you just try then and report back.

16" may fit over 305 Brembos, but not 330 Brembos. 17" needed.

Re the Giulietta wheels on a 159, worth noting that the G uses M12 bolts, but the 159 M14 bolts, so the bolt holes on the G wheels may need drilling out.

There's a set of Giulietta Turbine wheels on eBay at the moment with winter tyres fitted. Was almost tempted until I realised the load rating was too low for a 159.

Thanks guys.

I guess it is not worth trying out then. I have my winter tires stored elsewhere. They are not at my house. Not easy to get them just for trying.

I guess they will go on sale then.

also have installed giulietta 18" turbine rims on my 159 with 305mm brembos.
the only issue is the M12 hole form giulietta that you need drill out M14 159.

Hi, did anyone drilled bolt holes on Giulietta 17" alloys to fit them on 159.
I'm concerned for safety, will it be safe them to drive if they aren't perfectly centered/drilled. And how was to behave in drive, is there any issue since 159 is lot heavier.

safety should not be affected at all. wheel is centered elswhere, by 65mm diameter hole and corresponding element on other side. wheel screws and alloy holes are shaped the way that again screws will go straight.
holes needs to be bit bigger than m14 (15mm?), they cant be tight.
i never did this myself, but know that in Poland a lot of alfa forum members drilled giulietta alloys.
