Staggered Alloy Sizes

Hi Guys,
Wondering if someone can help me?

Looking to buy new alloys to fit my staggered set up but all the adverts I've seen display something along the lines of "The wheels are staggerd 2x8j 2x8.5j". I have no idea what this means ('ve Googled it but I'm still struggling), what alloy size would I need to allow for a proper fitting of the following tyres:

Rears - 255/35/18
Fronts - 225/40/18

Many Thanks

Staggered just means at the rears are wider to take wider tyres. 8" front and 8.5" or 9" rears will be fine. Standard is 8.5" rear. You look like you already have 18" wheels anyway though?
 
I do have 18's already but I really like the style of the MV2 & 3s....still deciding which I prefer.
Also the cost of refurbing mine which are in quite a bad state (laquer peeling and bubbling on all) I've been quoted at £350, so I thought why not just get new alloys instead for roughly the same cost (I was also told that the split rims could go again even after a refurb, I dont' really fancy paying out again when I come to sell).

Thing is 've never bought new alloys and have just become confused with all the terminology....stud diamater, offset, 8j/8.5j, part number etc. Have no idea what I'm buying...help!!

Cheers

Drop an email to http://www.alloywheelsdirect.net/ quite a few of the members have bought from them, including me
 
Your current front wheels are 8x18. So the wheel is 8 inches wide and has a diameter of 18 inches.
The wheel is 5x120. This means it has 5 bolt holes and the PCD (pitch circle diameter) is 120mm. This is the diameter between the centres of these bolt holes.
Both these figures are important because you obviously need 5 bolt holes to match your hub and the holes have to line up with your studs.
The offset of these front wheels is 47. In simple terms this determines how far in or out the wheel sits on your car so you must choose a wheel with a similar offset to your original.
Your rear wheels are wider being 8x8.5 so are described as being staggered. They are 8.5 inches wide and the offset is 50.
So basically you are looking for a set of wheels which I would suggest are 8 or 8.5 inches wide on the front with an offset of around 40 and rear wheels 8.5 to 9.5 inches wide with a similar offset. You can have the same widths front and rear if you wish. The wheels must be 5x120 to fit the studs.

Hope this helps.

Digging up an old thread as was trying to search for my answer instead of raising a new thread.

I'm in the market for some new 18" alloys after finding out my MV2s are replica so don't want to waste money on them getting them refurbed (which they are in desparate need of). I'm pretty new to all this so trying hard not to cock up when there's a fair bit of money involved.

I'm pretty happy now that I'm after genuine BMW (2nd Hand). 8 on the front and 8.5 on the rear and the tyre sizes to match.

The only thing that still confuses me is the offset. Buying 2nd hand, how can you tell what the offset is? Is it stamped on the alloys anywhere that I can get them to look? Do they vary within alloy makes (e.g. are their MV3 18" with different offsets) so I have to be careful to buy the right ones or are they standard for a particular model?

I've found some MV3's that I'm interested in but trying to make sure they'll fit.
 
Wheels are usually stamped somewhere with their offset (sometimes on the back so you might not be able to see it when it's on the car). Look for a number with the prefix "ET". So "ET47" would mean a 47mm offset, like your current front wheels.
 
The offsets of your new wheels do not have to be identical to the ones you are taking off as long as they are similar they will be ok.
Your best bet is to use this OFFSET CALCULATOR Just put your original wheel width and offset figure in the top and the new sizes in the bottom and press calculate to find out how the position of the wheel will be with your new wheels.
