Hey guys i just bought my first infiniti (G37X) and i wanted to upgrade the wheel size from 17 in to 18 in. I have 245/40/R18 winter tires and i was wondering if they would fit on 18in wheels on a G37X.
Also the wheels im buying have an offset of 45 would that pose a problem?

Thank you for the help, excited to start the infiniti life!

Yeah the wheel im buying has a width of 8 but would i have to get an offset of 45mm or less because i also thinking about running 255/40 on it.
Im honestly new to this whole offset thing

Would an offset of +40 work?

Thank you for all the help, last question i swear lol.
Should i buy the tpms that comes with the aftermarket wheel or do the OE ones work?

Would a wheel width of 8.5 with an offset of 40 be too wide ?

Or +35mm offset
