hey guys. i'm not too familiar with the whole tire sizing and what will rub with certain setups.

i just purchased some 350z 18'' 5 spoke wheels. The fronts are 18 X 8.0 and the rear are 18X8.5. i was curious was tire size i should be looking for that i will be safe and not rub or minimal rubbing. the diameter of the wheel/tire combo i have now are 24''. i'm lowered 2.25'' all the way around. i used the tire sizer in this thread but i just wanted to ask some of you pro's out there.

i didn't know whether to go with 235s or 245. maybe a 40 ratio wall?? i'm just not sure. its a 97. lowered 2.25'' and my current tire is 225/50 R16

Thanks guys!

24" is too small, stock diameter is 25.3". 235/40s will get you exactly 25.3" and I wouldn't go wider than that if you're that low and don't want to rub. Rolling fenders would help...

i'd go 225/235-40 combo, but that's me.

you mean 225 for the front an 235 for the rear?

Use that to compare overall size

well i've got a way to calculate overall size. i'm just wondering like the widest tire i can go without rubbing.

right now i've got about 2'' of wheel gap in the front and 1.5ish in the back. if i went with the 235/40 then it would be about 3/4 inches less wheel gap front and rear. and if i go with the 245/40 then its about an 1'' less wheel gap. i just would like to get as much wheel gap away without rubbing when i turn. those 350z rims have +30 offset in the front and i think +33 offset in the rear. so would 245's rub for sure? i don't mind so much about the speedometer being off...its been off ever since i've had the car.

I am lowered about the same amount as you and have the 350z track wheels. I am running 245/40/18 in the rear and wished I had gone with 235/40/18 cause I rub on the passenger side.

ok great! thank you Arisotezza18 for that info. i guess i'll be looking for some 235/40R18's! yeah i got the 35th anniversary wheels! i can't wait to put them on!

do you have anymore pictures of your current wheel/tire combo on your car?? thanks!

edit: nevermind i found one of your threads. love the wheels!

here's his car to show the drop and ya the 235 40 18's would work great kevin..

thanks Jaymi for posting that up! yeah i'm getting excited about those rims gotta find some tires....
