Guys I have a question regarding staggerd setups. As you can see from my sig below, I have a Q50 Red Sport and am currently getting the Infiniti "performance wheel package" which was offered in the 2014 - 2015 Q50 RWD models which consist of Ray Eng light weight wheels (370Z wheels). My question is regarding its staggered set up which from the factory the wheels are 19x9 front and back but the tires in the front are 245/40 and the rear 265/35. I'm planning on using the same set up but just wanted to confirm if this will work seeing as I have an AWD car and it won't mess up my ride. Granted this will only be used in the summer as I have a completely different winter setup. Other option is to use 255/40 all around maintaing the "square" set up. I'd post this in the Q50 forums but boy that place is just crickets..

So the wheels are square front and back, but tires are staggered? According to the tire calculator, the difference is 1.57% between front and rear tires. The general rule of thumb for AWD is to stay within 1%, but I've heard people tell me different and say it can be within 3%. I would stay within 1% to be safe, but to be even safer you could just run the same tires on all 4 (and why not, since the wheels are square). You could get away with 1.57% but you could see some VDC/Slip lights at higher speeds or hard cornering.

Goonz, here's a list of the best 19" AWD combos, getting well under !% is best and will insure you have no issues~

19s
225/45 & 255/40 0.06%
235/40 & 265/35 -0.37%
235/40 & 275/35 0.67%
245/40 & 275/35 -0.52%
245/40 & 285/35 0.51%

So if you have those tires included w/ the wheels it would be best to replace teh fronts w/ 235/40s or replace the rears w/275/35s. That 1.5% of those OEM sizes will probably trigger the AWD light at speeds over 80 mph (assuming your AWD system hasn't changed much since the G system)

The wheels did not come with tires thankfully so I'll be getting those shortly, without a doubt I'll be going with the Michelin PSS as I had an excellent experience with them on my previous coupe. I fear 275/285 may be a bit much for the 19x9 wheel perhaps in terms of fitment? I feel I should stay at the 235 fronts and 265 rears to keep it all in the 1%. Or I may just go with the 255/40 set up all around but if I'm getting summer wheels/tires then shoot I want staggered set up lol.

Oh, I missed that all four of those wheels were 19x9, the 255s would be the best mount on that width FWIW. And being able to do a true 4 tire rotation will make those summers last at least a little longer.

Yea I think I may go that route, I love the staggered setup and the look but I probably wont benefit due to my AWD. I mean I have to ask, is there anything wrong with going the staggered route?

No, as long as your not running too stretched or too pinched on the wheel mount. It would be better to run staggered tires on staggered wheels since you'd have a similar tire mount front & back. Ideally a 235/265 stagger would be best on a 8 to 8.5 front 9 to 9.5 rear.

Also, ideally it's best to have the slightly taller diameter in back since the rears wear faster, this will get your diameter variance closer to zero over time. If you start w/ a slightly shorter rear tire your variance could exceed 1% as they wear.

Might as well get a set of wheels that's actually staggered if you want the staggered look. Putting a 235 up front and a 265 in the rear on the same size wheels will just look weird as the rears will look more pinched than the fronts. If I were you, I would put 255s on all 4 corners on these wheels, otherwise I'd look into staggered aftermarket wheels and go with a 245/275 setup that won't mess with AWD and will look more uniform.

That's so odd though because that's how this package was offered from Infiniti on a 19x9 wheel with staggered tires (245/265). In any case I'm thinking sticking to 255/35/19. Michelin just released the newer version of the PSS called the PS 4S. I hope the 255/40 and 255/35 isn't that big of a change on all 4 wheels.

this is the label with these wheels

I'd lean towards the 255/40/19s since your OEM based size is a 245/40/19, the 255/35s would be almost 3/4" shorter (over 2.65% different than oem), the 255/40s would be a bit less than a 1/3" taller (1.17% different). This shouldn't cause any issues except a bit of speedometer difference, and should maintain the OEM ride.
It is interesting they did run staggered tires, I guess they were going for a sport pkg without having to invest in another wheel size, lol.

BTW, those 19x9" Rays are a nice setup, should be stronger and lighter, and look great too, a big WIN all around!

They look great, they aren't cheap by any means and many say to go after market route in terms of Vossen and etc but I'm not lowering my car so this was the best option in my mind. 255/40 all around in Michelin PSS have been ordered.

Never, I mean selling when the lease is over. Man the quality on the Rays forged is sooo on point!

Soo sexxyyyyy
