While these fit? What tire sizes are recommended for this setup?
Thanks

wow,
looking at these 20's in Pirelli's and Michelin's will give you a headache!
245/35/20 Front
285/30/20 Rear
(stock diameter 26.7"- 26.8")
255/35/20 F
295/30/20 R
(tad taller at 27"-27.2")
Pick your poison-Pirelli & Michelin have multiple dimensions of each of these tires.
Watch for how many /32" and traction temp. AA A (compound needs to be the same on front rear)
also where the tires are made,,,,that seems to make a difference in the actual size.
Bridgestone
Hankook
Yokohama
Lot's of other's offer only 1-2 dimensions of tire.
Good-Luck!

Well, this is what Front: 20x9.5 +45 with 255/40/20s and
Rear: 20x10.5 +25 with 295/35/20s look like on a 2010 Roadster (stock setup).

Not doubting you about stock set-up,,,just haven't seen another ~Z~ come with 28" tall tires from factory.
Appears that they fit though;any particular brand or model tire you like? also were you gonna lower your car any?

[jchammond]

Pirelli has 255/35's & 295/30's that are right at 27" tall & vary in width by origin of maker...5-7 tires the same size each. Germany,Italy etc....any particular tire brand you like?

please excuse my ignorance on tires and wheels. i just bought a 2016 touring. it came with 18" wheels that i despise. i would like to put 19" wheels on the car. i am only considering using a stock 370 wheels just, want them in 19". is my suspension basically the same on the touring model as other z packages? i am curious if they will fit without any modification? i also like the looks of some of the cars i have seen on here with spacers. at what point do you have to have camber kits that i have heard mentioned?
thanks

[Trips]

Yes,

They will fit just make sure the (offset) are within spec.

Depending on the offsets It may or may not need spacers

Keep the tire size to stock sizes IF you're not going to do anything fancy.

Only if you want to go with a wider wheel that will stick out past outside the fenders. Camber wil tilt top of the wheel, thus fitting it back flush with the fender.Lowering the car wil also have a tendency of cambering the wheels in, so if you decide to lower the car, you might want to go with wider wheels or larger spacers.

Stock 19" 370z wheels will only require an alignment at a regular old shop.

As stated above, camber kits can be used to increase negative camber when you have wide wheels that won't clear the fenders. They can also be used to decrease negative camber on lowered cars that will maintain toe/camber specs and increase tire life and straight line performance/grip.

But again, you won't need them if you're just using a stock wheel and are not lowered. Cheers.

alright guys. i need a confirmation on something.

is 3% the maximum tire diameter difference FR to RR? Will say 3.1% throw a code?

any speculation on whether or not an ECUtek tune can take care of the problem?

I'm running 275/35-19 PSS which is 26.6" and 345/30-19 PSS which is 27.2". With no issues.

yea, you are teetering right on the edge which is what even gives me hope, haha.

i have this hairbrained scheme about going 19"FR and 20"rear. I also want to run some serious rubber, but so far the closest i can come in terms of diameter, and keeping sidewall more or less the same, is 3.1% difference FR>RR (285/30r19 FR | 335/25r20 RR). my preferred tire selection would actually put it at about a 3.4% difference (285/30r19 FR | 345/25r20 RR), which i expect would definitely cause weirdness. obviously a wonky traction control system makes the idea a no-go.

edit: there are other tire choices that come closer, but i was hoping to run some 325+ on the RR. however, i like the sidewalls/diameter sizes of some of the narrower options.

sound's like you're after the ZR1 wheel set up,,,could be wrong-but i was thinking that 335/25/20 only came in run-flats.
Factory Diameter setup's are 325/30/19R & 275/35/19F ,The Michelin PSS tires are probably some of the widest tread ones.
"Rusty" has that Bad-Azz look!!!
i was thinking Pro-Street look 345/30/19R & 255/40/19F MPSS on 8.5 & 12" Forgelines.
or 295/35/19F on 10"wide wheel.
PS...."Rusty" also has unlimited funds!

You are spot on. the 285/30r19 FR and 335/25r20 RR setup is with PSS ZPs (run flats) same as the C7 vettes. I am not keen on the idea of run flats, but you can't argue with the handling success of the vettes.

Last night after spending some time with tire calculators and searching TireRack I also came across an alternative 275/35r19 FR | 305/30r20 on regular PSSs that would work better (2.2% diff FR>RR) and also fill the fender wells more (i.e. larger diameter than the wider ZPs mentioned). This option wouldn't create any problems with the TCS, but I lose width in the rear. It also has the advantage of being the same width as RS3 tires I will run as track tires.

So the 275/305 setup is currently my top choice if i decide to go 19/20. I expect the narrower rear tire won't have a major impact on traction. So, the only thing I lose is my spot in the "370z Wide Tire Hall of Fame", next to Rusty.
