Hey guy i recently order a set of 19x8.5 and 19x10 vossen cv1 stagger setup for my 2009 g37xs sedan and im currently lost on what perfect tire size to get can anyone can please give me some help im currently on the stock 18 inch wheels

 

Depending on your offsets and if you're lowered, or plan on lowering would have an impact on what sizes would be best. No drop and your wheels/tires will be out a bit compared to a dropped G. Hopefully your offsets are in the +35-45 range.
I have 245/295 setup on my dropped RWD. I would say a 245/275 or 255/285 setup would be a nice combo.
Use this tire calculator to find the best F&R tire sizes and keep in mind your new diameters F&R need to be within 3% +/- of your stock tire diameter and should be within 3% of each other from the front to the back.

Sorry for putting it in the wrong part but i was planning to get 245-40-19 & 275-35-19 but i checked the rpm and one is 781 and the other is 761 so thats whats stopping me from getting it atm

 

Anyone need help asap please still on my winter tires

 

Have you thought about 20" wheels?

I'm running 20x9 with 245/35/20 and in the rear its 20x10.5 with 285/30/20 on my G35x and have had no issues.

 

Can i get the link to that app?

 

Those sizes are very close, only .14" difference and 0.52% from each others' diameter, that will be fine.
Ideally though, if you can change to 20s the combo that CRV has above would be perfect, the 20 wheels cost more but the tires are cheaper so in the long run the 20s end up cheaper (assuming you go through a few sets of tires).

blnewt has been very helpful on my quest to find and fit wheels on my car.

But i agree thats the main reason why I opted to go with the 20's. When you compare the pricing of tires between the 19s vs 20s, it just makes makes sense and your wallet will thank you.

 

I am sure if you ask Diego@Vossen here on the forum he will be able to get you headed in the right direction. GL

 

Op Just Contact Diego with Vossen... he's the Guru of the Specs of our cars he help me Dial my CV'5s Squared and its on the Money ... though I may go from my 255/30 to a 265/30 after I run these down...lol

 

245/40/19 & 275/35/19 will be perfect. Those are the recommended specs.

 

Hi Diego,

I'm new here.....

So does that mean that my stock rim/tire on a 2010 Journey Sport that has the 225/45/19 and 245/40/19 will accept those larger tires (245 and 275) on my same rims? tx

I just bought this car four days ago and lthe original? Bridgestone Potenzas are shot.

 

Many G owners have used those sizes on stock wheels so yes that would be fine also.
