I just got a 2003 g35 sedan, I dont know much about wheels to be completely honest and I want to get some bigger rims for my car (at the moment I have the stock 17s by 7.5 i think). I like the look of the coupe 19 inch factory wheels but it seems that they are wider(8.5 i believe), when I was looking at the website for the new 07 sedan an option is to get the 18s that are 7.5 in the front 8.5 in the back so I am guessing having wider wheels in the back does not do any damage but is it ok to have anything wider that 7.5 in the front? basically I want to know what size rims I can put on a 2003 sedan? do bigger wider rims do any damage to the car? is there max width? do the front ones need to be thinner?

thanks, sorry if this is a basic question I just want to get an answer I can trust i dont want to have someone who is selling them to me lead me into somehting because of the price instead of what is good for the car

 

No they will be fine many people run the wheels on thier sedans. And welcome to the g35driver

 

You'll be fine, im running 8.5 front, 9.5 rears its fine.

 

I have a 2003 sedan with the coupe 19-inch wheels and stock suspension. Because the coupe wheels are wider than the stock sedan wheels (8.0 inch front, 8.5 inch rear), they will stick out further and be close to flush with the fenders. This doesn't create any problems, but you have to go with slightly smaller overall diameter tires to keep from rubbing the rear fenders. I originally went with a 255/40-19 on the rear, but the fenders rubbed over speedbumps. So I changed the rears to 255/35-19 and it doesn't rub at all. Some people go with the 245/40-19 on the rear and then just roll the fenders to make it work, but I'd rather no bend anything that isn't necessary.

As for the front, I originally mounted 245/40-19s and they worked good, no rubbing at all, plenty of clearance. But because I went from a 40 series tire in the rear to a 35 series, I changed the front to a 245/35-19 and it works fine. You have several options as I see them:

225/40-19 front
245/40-19 rear with rolled fenders

225/40-19 front
255/35-19 rear

235/40-19 front
245/40-19 rear with rolled fenders

245/40-19 front and rear with rolled fenders

(My setup)
245/35-19 front
255/35-19 rear

If you have any questions or want pics of how the setup looks, let me know by PM.

 

I have had 8.5" wheels on the front of my car since a few days after I got it.

One good idea is to upgrade your power steering cooler. I got one that is the same size and specs as the nismo one for ~$35. The extra weight and drag from the wider tires can put extra wear on your PS system so keeping the heat down is helpful.

 

GREAT INFO !!!!!!!!!! Thanks...

 

Good summary of options.

My setup:

245/40/19 F&R without rolled fenders, lowered on Eibach Pro Kit (1.1" F&R drop).

I was actually surprised that I don't rub with this setup because many people do with a 40 series tire when they lower their car. If you do plan on 40 series it would be wise to also plan to roll the fenders as it is a possibility you'll rub. Or better yet just go with the 35 series tire to avoid rubbing.

Coupe wheels on the sedan look great, go for it!

 

The coupe 18's are 18x8 +30 front and rear and fit pretty flush. I have them on my sedan.

The coupe 19's fit well too.

 

Really appreciate all the help/info/tips, Im glad I joined this site, I am going to go for it and get some coupe 19s for it, I may wait till the spring to put them on though (I live in NY so not great for winter).

Thanks for everything

 

I just put on the M45 sport rims with 245 35 19's all round. I have a inside clip on wheel weight hitting something in the left front when I make a hard left hander. I have some 5mm spacers coming that should take care of it.

They look unreal, I love em'.

 

To gixxersteve,

Hey thanks for all the info, if you could still put some pics showing what the set up you have
245/35-19 front
255/35-19 rear
looks like I would really appreciate it that. also how long do these tires last as far as mileage, and what brands or specifics should I look for when getting tires I will only be using them in the summer probably.

thanks man

 

My daughter has a set on her G35 sedan from an '06 coupe. They not only
fit but look great toooo! There's a few sets for sale on our Marketplace...

 

hey Texasscout, do you have any pics of your car with the M45 rims, I know someone sellign some and Im trying to decide btwn the g35 coupe 19s or those,

thanks

 

I had the 19" Coupe wheels for awhile dropped on 350z suspension. I only rubbed on huge dips and only on the passanger side for some reason.



More Info on the PS cooler. Where do i get one?

 

roll/shave the rear fenders and u can go as low as u want.
