If you are talking about these, they are 19" wheels that appear to be for the I4 with performance pack.

According to the specs we've seen so far, there is supposed to be a 17" wheel. And on some of the GT photos, there is an 18" wheel, which appears to be have only been seen as digitally edited.

 

My favorite so far.

 

Yes these, I think up near my OP someone had said these might be smaller rims, but if they are 19s they're a no brainer! BEst looking of all we've seen imo.

I wish Ford would relax the wheel combos, so that you could order any wheel on any model of the car, if you're willing to pay whatever premium that includes. I get how they package things now to try and get the customer to buy more but it still irks me. I'm sure it won't stop people from changing wheels later on.

 

Top to bottom
20 inch premium wheels (ecoboost and GT)
19 inch (GT option? car that had them on was a GT and it had summer tires on it) EDIT: these were nero A/S
19 inch (ecoboost performance pack)
19 inch staggered (GT track pack)

 

They are all-seasons on that wheel - P Zero Nero

 

I'd be looking to the aftermarket as the stock Mustangs wheels have never overly appealed (Boss LS and Brembo wheels aside).......

I love the looks of these. Very similar to the 20" wheel already seen (which is already similar to the Boss LS).......just with a little Morr

 

Those work nicely with the 2015 styling!

 

ahh good catch, i thought i only saw P zero, didnt read the next word, i should have just looked at the treads... makes more sense in the wheel hierarchy now

 

I just received my 2015 GT Premium with the 20" rims and 265/35x20 tires. I chose that option since my wife can't drive a stick and the PP is not available with the automatic. I was a bit disappointed until I saw my car (in the flesh) with the 20" wheels and I am 100% satisfied with the wheel/tire package. These wheels are spectacularly beautiful, give great handling, and I just saved myself $2500 in new wheel and tires.

 

I opted for the 20" with 265/35x20 Pirelli tires. That wheel is spectacular. I ordered an auto GT Premium and the PP is NOT available with the auto tranny. I got lucky with the choice and I love these wheels...and I won't upgrade either!

 

Something is confusing to me about the wheel options.

An ecoboost premium comes standard with the 18" "Magnetic gloss paint/Machined Aluminum wheels.

Then you have the 18" "Foundry low-gloss paint/machined aluminum wheels" available as a $155 option. No additional package required.

If you go with the base ecoboost, though, it comes standard with the 17" "Sparkle Silver Painted Aluminium Wheels". With the exact same 18" foundry wheels available as a $155 option.

Seems fairly crazy to me, the same price to pick those wheels even on the premium, which has obviously nicer wheels. Makes me think that you'd actually kinda be paying to downgrade your wheels!
