370z MEATY TIRE THREAD

[1LIFE]

Thanks a lot brother!! I'll have to study your posts awhile and it will click.. Definitely very helpful, ive never took the time to learn offsets. I actually have Nismo's also and running 305/30 w15mm spacers and 255(way to narrow)35 w 20mm.. the rear is slight bubble with slight stretch front, I don't mind the look. Maybe I should consider 12.5 Ill just copy all sizes

Well I tried to line the top line offset but it keeps reformatting when I try to post.. Wheels are SSR Executor CV01 super concave dish

I use this chart; pretty accurate/ remember that a wheels width is measured from inner bead to bead- so overall width is usually 1" wider than specs... That will help you... Also on this chart- it shows back spacing in inches/for the + & - offsets....hope this helps.

a little better understanding; it can drive you crazy- with custom wheels; you don't won't any spacers.... Gotta pin the tail on the donkey! Don't forget to upload any pics/ I'm interested in same configuration- just lack of $$$ rite now- off to work & have a good day!

guys ...whats the widest tire choice i can go with on oem 19" sport rays without any issues. i have 20" spacers in rear and my car (2009 370z base) is at standard height.


Any recommendations? Tire/dimensions/make

I'm no help, cause I got base 18's... But if you scroll through this thread-you will see a lot of different combos. Just be sure you are using same diameter tire in front or drivability malfunction will occur. I run 245/45 & 275/40 on factory 18's...8" on front & 9" on rear. Both tires are 26.7" diameter..they work great. (Hjust for example) . Have a good day & im sure you will get some comments.

[jchammond]

Can't believe nobody else has posted/ so I'm gonna give it a whirl.... Not sure about your spacers though.

notice these are Michelin Pilots, a bit wider than other brands... This option is 26.3" diameter.3"-.4" shorter

big boys in Michelin.. Same diameter/ would go in rim but will most likely bulge somewhat

Cutting it in half, adding another piece of aluminum, then welding all the aluminum back together (which I don't know how familiar you are with but it's very difficult for someone to do properly and will never be as strong as it was before it was cut) is an iffy process. Those wheels are not recommended for anything but a show car that does not drive at high speeds and just sits most of the time for show.



On steel wheels it's more acceptable (although I would never drive on a wheel like that), but on an aluminum wheel it's just out of the question for me...I wouldn't pay anyone to ruin my Nismo wheels and make them extremely dangerous to drive on...a pothole could easily crack or seperate that aluminum weld. It's better to just spend the money on new wheels and do it properly. Although honestly I don't see the reason of going with 345 over 325 or 335...There's barely a difference.

thanks for the info, u changed my mind.

I've just been reading so much about ppl not having any problems even with track cars and drag cars that I figured it was fine.

but for tire width going from 325 to a 345
I guess it's the same reason ppl go from 285 to a 305.

wider wheels more traction after super chargers installed for me but so far I think I'll still go with 325 on a 12" wheel just because I don't want the fluffy balloon look
