Hi guys I just got into some g35 wheels and was wondering what size of tires should I use my car is not drop so any suggestions thanx
Rite now had a week old set of 235/45/18

 

235/40r18 is closer to the correct height.

 

I have some 245/45/18 rims and tire new take offs from a 2011 Max. They fit but are big. Next set I'm going took to a 245/40/18. Discounttire.com has a tire size calculator on their website that gives you dimensions, revs per mile and even what to expect your speedo to read depending on the change in size.

 

Here's a nice tool as well:

BTW ... I'm running 235/45/18s on 18x7.5s.

If I'm not mistaken the off-set is +40

 

or 2000-2003 OEM 17" rims with 235/45/17
