2015 Mustang GT Premium w/PP
So I'm currently rocking the 2015 Performance Package tires on my Mustang GT Premium. My current tire sizes are 255/35 ZR19 96W on the front and 285/35 ZR19 103W on the back. I'm looking at purchasing the gloss black SVE R350 wheels here:

Will my current tires fit? I'm also trying to decided whether to just go 19x10, 19x11, or 19x10 in the front and 19x11 in the back. Thanks again for the help!

19x10 square is the most practical setup.

10/11 staggered front/rear kills your ability to rotate wheels (you won’t anyway with your current staggered tires) and handling balance won’t be as neutral as 10 square, but its an easy fit if you really want an 11” wide rear tire.

11 square is possible, but that 255 front tire won’t fit the 11” wheel and you need extended studs and 25mm (slip on) spacers and probably camber plates to fit the 11” front wheel properly. 11” is good for road course work, its overkill for the street.

Hi @NightmareMoon ... I need some advise. I am almost ready to place and order for my new wheels.
To be honest i was tempting to go staggered 20 x 10 and 11 but your comment got me thinking as in my case it is a daily driver and no track at all.

Like the idea to go square so i can rotate tires. Will you see any issue of i go square but in 20" or should i stay 19"?

Also i am set on the Vossen HF-3 and seems that i can only go with their standard specs on their rims and offsets but i don't like poke and love the concave on both rims (front and back). This is why i am more inclined to the 20 x 10 but the offset of +45 have me worried on the front.

Thanks in advance for your lighting and advise.

Here are the standard specs of the Vossen rims in 19":

19 x 9.5" 5x114.3 +40

And here in 20:

20 x 9" 5x114.3 +32 / +38
20 x 10" 5x114.3 +45
20 x 10.5" 5x114.3 +45

Appreciate your feedback.

With a 5mm slip on spacer up front the 20x10 ET 45 would be fine for a square fit. (Maybe fine w/o it) Its not as aggressive as say a ET35 but the difference is only 1cm.

ET40 and ET35 are common offsets for square 10” wide wheels for our cars. ET45 is close and with a 5mm front spacer would be the same as an ET40. On the rear an ET45 would be just fine.

Thanks. I really appreciate it but i will try to avoid the spacers. Would yo go 20" or stay 19"?

Well, I’ll admit I don’t have first hand experience with 20” wheels on these cars.

In general, 19s are a good compromise, just mind the wheel weight and sidewall thickness if you go 20s. Too heavy and/or too short of a sidewall and the ride will suffer. IMHO 19s look great if they’re a good offset and flush with the fenders.
