Considering upgrading to OEM coupe sport 19s vs my sedan sport 18s, but unsure about weight gain. Does anyone have these specs for both cars' wheels?

thanks

 

OEM 19" 10 spoke G37 Sport wheels & tires

Front:
Wheels: 19"x8.5". Cast aluminum. Made for Nissan/Infiniti by Enkei. Weight: 26.5 lbs. Bolt pattern 114.3 x 5 Offset +43
Tires: Bridgestone Potenza RE050A 225/45/19 92W. UTQG 140AA, weight 27 lbs., tread depth 10/32"

Rear:
Wheels: 19"x9". Cast aluminum. Made for Nissan/Infiniti byEnkei. Weight: 27.5 lbs. Bolt pattern 114.3 x 5. Offset +45
Tires: Bridgestone Potenza RE050A 245/40/19 94W. UTQG 140AA, weight 30 lbs., tread depth 10/32"


For the sedan:

"24 lbs for the front and 25 lbs for the rear"


Not 100% on the sedan wheel weight. That's what I found with a quick search.

 

Just a few pounds heavier but 100x better looking, I'd do it in a heartbeat

 

Thanks! Are the offsets compatible? I've seen pics and they seem to look ok but I can't seem to find what the sedan wheel offsets are... searching again...

 

The Sedan's OEM 18's are not the best looking wheels IMO

 

sedan wheels are 18x7.5 w/ +45 offset in the front and 18x8.5 +50 in the rear.
Tires are 225/50/18 and 245/45/18.

sport coupe is 19x8.5 +43 26.5lbs and 19x9 +45 27.5 lbs
tires are 225/45/19 and 245/40/19

ive got them on my sedan and it looks like they came on there from the factory. offsets are perfect.

 

Good deal, thanks.

Debating between stick with OEM sedan 18's and shoe on PSS's, try to find some OEM coupe wheels and shoe on PSS's in the factory fitment size, or third- get some avant garde M310s in 8.5/9.5" widths and shoe on PSS's in coupe factory fitment (225/245). Between two and three, I feel three wins unless I can find coupe wheels for significantly less than a grand.

The first will yield the best performance and ride, but isn't as pretty. Tough one, because I'm usually a form follows function kind of guy.

 

IMO 19s or 20s will give you better performance (all things being equal) due to the stiffer sidewalls, now ride is definitely firm, but I love it that way.
I'd jump on those coupe wheels, you should be able to find some in your budget. Those ugly 17&18" wheels on the current G sedans really take away from an otherwise beautiful car IMO.

 

Indeed, but for clarification I'm coming from the perspective of weight savings when I say the stock wheel and tire combo will probably be the best performer. This is particularly true in that I'm primarily considering stock tire widths

 

A couple of pounds of wheel weight DOES make a difference. Try to offset it with a lighter tire.

C&D did a report some time ago - measuring the effect of larger/heavier wheel/tires. Basically - as wheel size went up, weight also went up. As weight went up, performance and MPG went down.

Found it: http://www.caranddriver.com/features...d-tires-tested

When it's time to replace my RE050's - I'll be looking for a high performance but LIGHTER tire.

Also - anyone know the weight of the Journey 17" wheel??

Thanks

 

Really, you think these are not very good looking?

 

Yeah, these are so ugly...

 

Those aren't the ones on the 2010 MY but I agree they aren't the most attractive...

 

Indeed!

I'm going to go with pilot super sports
