I have 19x8.5 front & 19.9.5 rear wheels. For tires, can I do 245/40/19 front & 275/35/19 rear with no issues/problems? Or should I go with 245/35/19 front & 275/35/19 rear? Your thoughts??

 

If you own a 350Z you will want the 245/35 and 275/35 combo , if your driving a 370Z the 245/40 and 275/35 is what you need. Your call

 

all four of my rims are 18 x 9.75 and in the front i have 255/40/18 and in the back i have 275/45/18. no issues whatsoever

 

that sir, is ridiculous. terrasmak has told you all that you need to know

 

I'm not the OP, just giving my opinion on my tire set up and i have no problems. I actually have a better handling on her.

 

Do you want a cookie? The OP is running 19's and if you actually had the tire sizes you listed you would have problems. My bet is your rear is actually a 275/40-18

 

buddy, i dont know why you're talking BS. I posted the sizes of my tires, i have no problems.

 

Those would work, but the 275/45 REARS are 1" taller than stock dimensions..that would result in SLOWER acceleration and almost a 4% error in speedometer. Also VDC would prolly be triggered if you had it.
275/40 is a much better choice...also handles better because of less sidewall flex.
BTW...you have 9.75 wide rims? Never heard of that?

 

Please post a pic of those tires on your car, make sure your rear tire size is readable in the pic.

 

+1 ... Run that setup with my G, Except I run 275/30 rear.

 

I am looking at putting some Enkei PKR's on my stock 04 350z, 18x8.5 with 245/40 on the front and 18x9.5 275/40 on the rear wanted to see if anybody had any experience with this setup or had any thoughts/suggestions? Thanks for the input.
