Hi everyone, first off I have a 2003 350z Touring with stock wheels and tires size 225/45/18 front and 245/45/18 rears. 45mm offset all around

I just bought some new rims Rota DPT 18x9.5 front and 18x10 rears. 35mm offset all around.
I want to put the stock tire 225/45/18 and 245/45/18 on my new rims. Is it possible and is it gunna be a stretch and if so, is it ok?

second, I want to get some spacer to make it a lil more flush then usual. What spacer should I go with, I know 10mm spacer will get my wheels back to stock offset specs so should I run 20mm and 25mm in the rears will that cause any rubbing?

Please take the time to help me with these question and all advice and help appreciated. Thank you

 

http://www.1010tires.com/wheeloffsetcalculator.asp stock specs are 18x8 +30, now just figure out how much further you want them to stick out.

Hint with the tires you want to run "large spacer"

 

I will let you figure this out on your own... Terra got you off to a GREAT start...

 

After getting your tires, you can choose spacer by:

1) Mount tires & get alignment sans spacer
2) Use a metric ruler or caliper to measure from the face of the top of the tire out to where you want it to be in comparison to the lip/fender
3) Determine if you need to roll fender to get the look that you want

Buy spacer based off of your measurement, because a calculator is only going to be so accurate when your drop, alignment & personal preference can make a difference.

 

For wheel-tire width see: http://www.tiresandco.ca/equivalency-tables-advice.html

 

So any suggestion on which spacer and according to the tire width link I cant run 225/35/18 on 9.5inch rims?

 

I was thinking running 245/40/18 front and 275/40/18 rears
Anyone think thatll be good on stock springs? And do you think 40 offset on the tires is good for 35mm offset on my new wheels?

 

275/40/18 : Actual speed 100.0 MPH. Speedometer will read 100.07 MPH. Cant get much better than that.

 

255/40 front will also work great, stock height or lowered those the a set of the proper tires for the car.

A very common wheel combo is 18x9.5 +15 front and 18x10.5 +15 rear, use the link i posted and work the numbers a little to figure out what specers you will want.
