I am looking at an 18inch wheel package for an 05 x.

the package includes 225 45 18s.

I was wondering if anyone can comment on the handling characteritics of going from stock 17s to this size and if there were any negative effects. I know I will have a stiffer ride.. I was wondering about gas mileage, drive issues...

thanks

 

I went from stock 17s to 235/45R18 wheels and tires on my 05 X and the ride is great (don't even notice any stiffer ride) and the handling has greatly improved, especially going from the Bridgestone All Seasons to a summer performance tire.
My wife agrees with me that there were no negatives with this swap they were all positive results . As long as you keep the same size wheel and tire on all 4 corners.

Hey Wayne, just wondering, was there a difference in offset? I read somewhere on this forum that the offset of the stock wheels is 45mm. Also, did you lower your car?

Steve I stayed with stock height because we are driving over closed roads on occassion during the winter and we need the ground clearance then. I live an area of horizontal snow (bad drifting and whiteouts).

As to the offsets, The stock 17" is 45mm and the optional 18" Infiniti 05 sedan sport wheels that I recently acquired are also the identical 45mm offset.

Thanks for the info. Even w/o the drop, your car still looks great.

 

Wayne, I want your wheels !!!!!!!!!!!!!!!!!!!! I might have to take a trip up to Canada and ****** your wheels while you are not looking Just Kidding!

Is anyone selling their 05 model 18inch sports wheels? By the way, how you get the offset information?

Also, can you post a bigger picture of your car with those wheels? Is there a lesser fender/wheel gap with the 18's now?

 

Bobby, the offset info for those wheels is in your Owner's manual, I got the wheels complete with the tire pressure sensors so everything still works great.
The wheel gap is the same since the tires are basically the same outside diameter , just lower profile and wider.
Did you click on the pic Bobby, to make it larger, I have to reduce the pic sizes so they will post here , I don't know how the others can keep them larger.
Wayne

 

I gotta check the manual then. Yup I clicked on it but still kinda small. Not sure how some people post huge pictures. Where is the tire pressure sensor located? Mount into the wheels?

 

The tps is mounted on the inside of the rim with the valve stem.

About the pics, I found out how to post larger pics here, but they (Godzilla, the site owner) would prefer them the size that I posted. I respect that and understand that if everyone posted full size it would take up too much space.
If you want bigger pics Bobby, send me your email addy via PM.

I took off the OEM 17s and replaced them with 18x8" Moda R6s and 245/40 Yokohama AVS ES 100s. Ride is not much different, but handling was improved a great deal. The wheels are 45mm offset. I would have gone with a 38mm, but I bought these wheels for the 03 Max SE the G replaced. No rubbing issues at all.

 

...

 

I have the same setup as you 05 18's on an 05 X. Anyway if we get a flat I think the width of the spare may be an issue...I have the full size spare 17x7 215/55/17.

Anyone have any input on this?

 

I am curious too. For you guys that moved onto 18inch wheels. You can't use your spare 17inches when it goes flat right? Otherwise, one of the wheels might not be touching the ground much.

 

RichK, pardon my stupidy with "offsets" on the wheels. If you have gotten 38mm vs 45mm what is the difference? Perferrably people want positive or negative offsets?

 

Mikeee2,

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel.

As for the 17" spare the the overal diameter is the same as the 18".

215/55/17 = 235/45/18
