Bought new wheels/tires but is this right ?

[mrbtd]

Purchased some wheels for my daughters 2008 Altima Coupe. After a bunch of research here I decided 18 x 8 with a 35 mm offset with 245 45 18 tires all the way around.

It does not look like I will rub anywhere but I am sticking outside the middle of the fender by almost 1". I reviewed hundreds of pictures with larger wheel and tire configurations and never noticed this. I am thinking it is because of the angles the pictures are being taken but would like help confirming it is OK to run it this way.

did you get the correct bore size? if you didn't, the wheels wont fit on the hub correctly. 18x8 +35 should not stick out at all. verify that the back face of the wheel mounting surface is flush against the hub. If it is, then you should be ok.

The factory specs of the 18" OEM wheels are as follows: 18x7.5 (45mm) offset with 235/45/18 tires. The setup you purchased for your daughter's coupe is more "aggressive" than the OEM specs. The wheels you bought are .5" wider, and the offset is 10MM more negative (protrudes from fender) and the tires are 10MM thicker. However, the setup should not result in any sort of rubbing under normal driving conditions--- if I understand your post correctly.

If you want to ensure the coupe will not experience any rubbing on 18" wheels, the easiest and safest method is to simply ensure that the aftermarket wheels you purchase match the 18" OEM specs. When a person decides to upsize wheels they have to make adjustments to address factors such as wheel size, width, offset, tire size, and ride height to ensure proper fittment. You simply cannot purchase what fits a wheel(s), and/or what wheel will mount to a car and expect the same look across the board.

Thanks for the help guys. I did realize it was a more aggressive set up and that is what we were going for. I wanted to stay with the 18" for ride quality and after comparing images and offsets for example 9" or 8.5" with varying offsets I thought I had it right to get a flush look.

I am going to remount one wheel this afternoon to get some better pics. I could of missed something obvious.

[mrbtd]

Here are some more images (click on image for larger). I confirmed the marking on the wheels and they are indeed 18 X 8 with a ET35 (I presume this is offset). Confirmed the hub size and it is mounting flush to the rotor.

Now I said "new wheels" earlier and I should of said new to me. They are second hand (eBay) I dont believe they have been misrepresented or anything like that because of the markings on the wheels.

OEM set up


You can see here they are well past the mid point in the fender

All looks right here

The wheel poke that you have shouldn't cause any exterior fender rubbing, unless the suspension were to be compressed to it's max threshold or if the car is lowered more than 1"-1.5". There's plenty of gap between the tire and fender lip. However, you may want to check the interior clearance to determine if the wheel/tire combo you purchased is going to rub any of the car's interior suspension components.

[mrbtd]

I did confirm the clearence in front and back and I am OK the thing that concerns me is the poke. Is this typical ? Figure to get it back to flush with the feners the offset would of needed to be about 60.

[seldomseen]

The wheel poke is fine, people drive with this sort of set up all the time. A +50 offset would give you a flush look, you could probably get away with a +45 to +47 too for a flush look. +60 would be to much and cause interior suspension rubbing.

[SanoSuKe]

This is very fishy man. +35 offset should not be poking out that much. No, this is not typical.

[AlexN09]

I'm assuming the offset is misrepresented. Have you taken your tape to measure the actual widths of the wheels? Perhaps you could google exactly how offsets are accurately measured and find the true offset of your set. It looks pretty aggressive to me.

[mrbtd]

Thanks all... I do understand the concept of measuring the offset. Not going to be easy to mark the center of the rim and then get to the hub but I will get it done this afternoon.

Again though since the wheel markings say et 35 and 18 x 8 I would think it's OK. I figured material would of had to be added to the hub to make it less than 35 and there are no signs of it.

Was thinking about the sidewall of the tire. I have a bulge there and I see most set ups do not. I understood that rim width does effect this but 245 45 on a 8" wheel looks to be in spec.

The tires are Nitto Motivo 245 45 18.

[seldomseen]

Based on the verticle picture you posted...the offset would appear to be +35, particularly when you take into consideration the the 245 tire series you have and the 8" wheel width. If I understand your post correctly, the tire buldge you're referring to is due to the 245 series tires. If the wheels were wrapped in 225 or 235 tires...the buldge wouldn't be as pronounced.

[mrbtd]

OK researched how to measure the offset myself and I did get back spacing of just over 5-1/2" and confirmed it is an 8" width. This tells me I am just under 1-1/2" away from the center of the rim (1.4 * 25.4 = 35.56 ) so I am going to say the offset is indeed 35mm. No way it is something like 30 or 25 anyways. I realize it is not a perfect measurement because of the tires being mounted but I feel pretty good about the wheel being right. Another thing I noticed is the stainless lip on the wheel is protuding at least 3/8" from the true edge of the wheel so that is making it look like there is more poke than there really is.

This leaves the tire buldge factor with the 8" width and 245 /45 tire and me determining what flush really is....

I am guessing that I will have about 3/4" less poke with a 235/45 tire (considering 1/2 of the width difference) and the buldge factor that would get me within a 1/4" or so of the wheel well which is the look I am going for. I knew going in that I would need new tires sooner rather than later so not a big deal to get that sorted later on in the summer hoping its safe for her to drive it now.

It seems you guys agree it is safe as is ? I know the speedometer is going to be slightly off while the 245/45 tire is on.

[AlexN09]

I would feel completely comfortable driving on that size as long as the tires themselves were in good shape.

[seldomseen]

The wheel setup you purchased is safe and can be driven on without issue.

[VTMike24]

Based on the additional info it sounds like you should be good to go. Your setup is fairly close to mine which is what threw me off. I run a 8.5" rim with +35 offset and 235 tires and I'm still not flush. I guess the 245 tire is the difference.

I have plenty of room with my setup and I'm lowered on springs, so I think you should be fine as far as rubbing while turning.

Purchased some wheels for my daughters 2008 Altima Coupe. After a bunch of research here I decided 18 x 8 with a 35 mm offset with 245 45 18 tires all the way around.

Back in the mid nineties when 18" wheels were considered big. We used to wrap 18's in 215 series tires to accomdate a slammed look. But then the 225 series became the newer standard to improve ride quality and reduce wheel damage.

[BamaCoupe]

This is odd; I too like VTMike have 18" 350Z wheels on my car (just different style; Anniversary vs. Track wheels). My fronts are 18x8 30mm offset and rear's are 18x8.5 with 33mm offset, and mine do not extrude the fenders and quarter panel. OEM is actually 235/45-18's rather than 245/45-18's though, but you're extruding more than 5mm (10mm total; 5mm per side of wheel).

[seldomseen]

He said the wheels were stamped with the specs...therefore, it's unlikely the information is bad. And based on the picture showing the wheel fittment vertically. Everything seems to be as expected, and consistent with the wheel and tire combo that he has.

[BamaCoupe]

^ What? I just brought up that he did go with the wrong tire size, not anything about his offset being stamped wrong on the wheel. I'm wondering if the wider tire is causing the extrusion rather than the wheels; I’m wondering if the wheels are flush while the tires are what is doing the extruding, but like I said an additional 10mm of tire (a 245 rather than a 235) would probably not make that much of a difference.

BTW --- How's your daughter enjoying the new car?

BTW --- How's your daughter enjoying the new car?

Thanks for asking...She loves it. We bought it for her and both me and my wife drive it every chance we get.

Funny how changes happen...I ran across this site looking up a headlight issue and saw the images of new wheels and etc...I made the mistake of pointing it out to her and it was over from there, now the stockers are winter tires.
