Thx much to those who are serious. I understand I'm being kinda nooby but I've gotta learn some how. Thx again.

you learn by searching, not being spoon fed the answer.

18x9.5 +15 off front, 18x11 +15 rear.

im planing to buy tires size 255/40/18 front and rear 275/40/18 and i was wondering if this will rub, or should i go with 245/40/18 front and 265/40/18 on the back. At this moment the car is on stock suspension but i would like to drop it with eibach prokit. thanks.

There are resources and sources here on this forum (besides the ability to ask questions) that are very helpful.

Try this: https://my350z.com/forum/tire_rim_calculator.php

Read the FAQ.

Also, support the vendor/advertisers on the site. Ask them product questions and they'll be happy to answer in hopes you'll buy from them (as it should be..... But also, don't waste their time if you have no intention of buying from them.) I have personally done biz with at least three of them in the last two months. Free plug: Tire Rack - lonnnng time customer, THMotorsports, ConceptZPerformance.... They've all been great!

The new TSW Bathurst wheels have caught my eye. My 350z has no suspension mods and is at the stock ride height. The Bathursts I'm considering are 18x9 30mm and 18x10.5 27mm in the rear. Would I run into trouble with 245/40F and 275/40R tires? I'd like to keep the stock ride height because in my opinion my car rides rough enough as is, but I'd like to avoid silly amounts of fender gap. Thanks!

you should be fine at stock height but going that width the shoulder of the tire is going to be rounded (aka slight stretch) terrasmak will be able to lead you better than me

Wow thanks for the quick response. I'm definitely not a fan of the stretched look. Maybe I'll just put 18x9 all around with a wider tire in the rear.

i ran 9.5 width on all 4 corners with a 255/40 front and 275/40 rear and they were pretty squared up

Hi Guys,

Would like to upgrade the wheels for my 08' Z.
More interested in those with concave spoke.
Can anyone suggest some (18" or 19")?
I tried tirerack.com but they seem to have very limited selections.
Thanks.

The biggest variable with your question is budget. No one can suggest anything without knowing how much you are willing to spend on wheels and tires. Also, check out the vendor classifieds, specifically the wheel and tire section for good deals on wheels for your Z.

you need 5x114.3 lug pattern and you can get up to a 9.5+15 in front and rear without rolling or major suspension work..... do some homework

Stock 350z no spacers w/brembo
18x9.0 5x114.3 +35 front
18x9.5 5x114.3 +35 rear
245/40r18
Also would they work with 15mm spacers? Thank you

travlee

essentially you would be a +20. 245 will be stretched on the rear and okay on front

nvmynismoz

Thank you

but if it were me i would get something that has a better offset, closer to a +15

nvmynismoz

Would you prefer a 18x9.5 +22 all around instead? Thank you

its not about me... i am just advising you to what would look better without spacers
