Max wheel offset for 97-01 Q45?

[emoq45]

I'm looking at purchasing some wheels but they have a 32 offset. I looked at some website and the Q45 desired offset range is 35-45. Will these wheels fit without any problem or do I need to do some other stuff to make them fit?

Also anyone who has 18 in. wheels on their Q45 post em up! The wheels are 18s and I need to see how the size looks on the Q. Thanks!

To say for sure if the offset is "okay" you have to reference the wheel width. The 2 are combined to understand the wheel/tire relationship to the suspension adn fender.

Not to mention the tire you wish to mount. After all, the tire is all that contacts the road, nothing else.

Ok, I'm going to write a bit here because I once also wanted to know this and have learned so I'm going to pass the buck so you can teach somebody else. That way all the "will these fit?" questions that you see on every single car forum on the internet can finally be a thing of the past.

when picking a wheel there are two things to be concerned with... front spacing and backspacing.

definitions:backspacing is measured from the hub mounting surface to the nearest thing behind the hub that will interfere with the wheel. This is usually the struts/coils but sometimes can be other suspension components.front spacing is measured from the hub mounting surface to the nearest thing in front of the hub that may interfere with the wheel which is as far as I know ALWAYs the body. keep in mind nearly all fenders have horizontal lip that takes a few mm off your flushness if you don't have them rolled. now some cars like monster trucks... have no worries about the body interfering with the wheel thus they have infinite front spacing. Another thing to be concerned with is the front spacing for the rear is much easier to figure out as the rear wheels don't turn (usually). the front ones do however thus if your tucking tire and your COMPLETELY flush, you won't be able to turn without rubbing so you should probably be a little more conservative with the front offsets.wheel offset is the distance from the center of the wheel to wheels mounting surface expressed in +-mm plus being the mounting surface is closer to the body than the center of the wheel and minus being the mounting surface is further from the body than the center of the wheel. what this means is the lower the number the more wheel comes out from the hub or the more negative the offset the more wheel will be sticking out from the hub.wheel width is the width of the wheel expressed in inches... pretty self explanitory.

now you know what all the numbers mean you want to figure out what the font/backspacing is on a particular wheel given the wheel width and offset. thats also pretty simple math. lets take a wheel thats 18x9+40 and find the front spacing and back spacing...back spacing - take your 9 in width and convert it to mm. this can be done by going to google and typing int "9 in to mm". now divide that number by 2 and you have the distance from the center of the wheel to the back of the wheel in mm, now add your offset (which means lower the number if the offset is negative) and you then have the backspacing of the wheel expressed in mm, you can change back to inches of you want using google again. lets do this for our wheel... 9inches/2 = 4.5inches. 4.5 in to mm = 114.3mm. 114.3mm + 40mm = 154.3mm = 6.07inches.front spacing - most of the work is done, take your halfway point you did above which was 114.3 and this time subract the offset (which means the number is bigger if the offset is negative) and that is the front spacing thus 114.3mm - 40mm = 74.3mm = 2.92 inches.what that means is that you need to have 6.1 inches from the wheel mounting surface back and 2.92 inches from the wheel mounting surface forward.

now for you car... the easiest way to know the max front and backspacing available on your car is to measure it... but falk just bought a set of wheels and says they are pretty flush so lets take his sizes...his front spacing in the front is 96mm and the rear is 102mm his backspacing is front 132mm and rear 152mm.

so if you go by that then you can calculate your spacing of the wheels your thinking of and know, i'd be xmm further out than falk. or furthin in probably.

maybe falk can jump in and let us know if his fenders are rolled or if he has some extra camber and if he thinks there are a few more mm available in front or back.

sorry for putting in so many details and I hope this helped.

ohh and if anybody sees anything wrong please chime in and I'll fix this, I think we should revise it a make it a sticky along with a table of measured front and backspacings for various cars. (G50,Y33,F50 ect.)

As the post above yours states, you forgot the most important part, the tire. Wheels without tires are useless.

For quick reference, my 19" wheels are:

Front: 19x9 +18Rear: 19x10 +23

I had 18x8 and 18x9 a long time ago on my Q, they were effectively +20 offset with the 1" spacers I ran.

... I had 18x8 and 18x9 a long time ago on my Q, they were effectively +20 offset with the 1" spacers I ran.

So they were +45's?

Pics for reference so Ross could add them to the fitment thread would be great. And the tires sizes as well .+

Not to mention the tire you wish to mount. After all, the tire is all that contacts the road, nothing else.

And without the wheel, the tire would never be able to connect to the car ...

HEY WHILE WE ARE ON THIS TOPIC will 22x9.5 +30 offset 5.45 bolt pattern rim fit with maybe 245/35/22 tires or 255 or 265 anybody?

supposedly these are 22" inch rims

Im looking to put these on my q similar but 22's not 24"s

along with a kit hopefully if the deal for it gose threw

[NyRider]

I know I know dont knock me for wanting 22"s to all his own lets just say I have a drive way like this more pictures of this driveway herehttp://leenks.com/gallery499.htm
