255/35/19 and 295/35/19 on a G35 ?

[MP1ce]

Hello Everyone!

I just purchased myself a set of 19" Avant Garde Matte Black Wheels
They are 9.5 wide in front and 11 in the back with 20/18 offsets respectively
I am thinking of putting 255/35/19 Michelin pilot super sports up front and 305/30/19 pilot super sports in the back.
I have a red 2003 Infiniti G35 with brembo Brakes.

I would greatly appreciate any suggestions!

Just realized that 255/35/19 and 295/35/19 would prolly be a better bet
Can someone help, are they going to rub?

I didn't remember the OEM wheels specs, but use 18x7.5/8 +40.

You should be able to measure and compare.

Wheel Comparison:
Your proposed front wheel will stick out 45.4 mm farther than your old wheel.
Your proposed rear wheel will stick out 60.1 mm farther than your old wheel.


Rear Tires:
Package is 3 mm (0.1'') closer to suspension/brakes components. Acceptable for most cars.
Package will stick out 47 mm (1.9'') farther. Make sure that you have enough room under the fender. If not, consider narrower tires or higher offset.
Will fill out the wheelwell by extra 6 mm. Acceptable for most cars.

Front Tires:
100% clear (leaves even more room than OEM)
Package will stick out 35 mm (1.4'') farther. Make sure that you have enough room under the fender. If not, consider narrower tires or higher offset.

Factory 18" specs are 18x8 +30mm offset

What exactly does the wheel offset means, my offset is 20 in front and 18 in the back. What exactly does that mean?

the more i research the more i think that 295/35/19 and 255/35/19 is a good bet, the diameters are almost identical, i will have to roll my fenders no matter what from what i understand. The only issue that i'm failing to figure out is whether this 295 tire is going to rub against any suspension components.

See the section concerning offsets.

That setup will work with 255/295 tire sizes. Hopefully you are going to lower the car because that back setup is pretty aggressive and will need a bit of negative camber.

i got 245/35 on front and 275/35 in back on 9.5 and 11 inch racing harts on my car and its perfect i wouldnt go wider cause mines close to both sides with the 275s , u could roll the lips but i think 285 would be close after that

So i went with the 255/35/19 and 295/35/19 BF Goodrich, the car is in the shop getting a bunch of suspension work done to it, ill post a picture when it is ready in about two weeks.
I appreciate everyones input!

I have an Injen CatBack, Injen Cold Air Intake,

Work being done at the moment:
1) kinetix intakte manifold
2) megan racing Header(with straight pipes together)

I need to replace one of the shocks( i have a K sports coil over set)
But instead i want to buy an entire new coil-over set, because im not really too happy with what i have, Can anyone suggest a good value for the money deal, budget: $1500

Also after bolting all these aftermarket parts on i heard that a good ECU tune
can make a huge improvement. Is this true? Can Anyone suggest a solid ECU Chip?
budget: $1000

Shoot a email over to Mike at tunerzstore.com for ECU tuner. He can hook you up.....or just wait as he will probably respond here.
