Default Safe amount of offset on the wheels?

Hi all,

I'm still shopping for nice wheels, but I noticed that it is difficult to find nice wheels that have a 50 offset (my 15" contour have a 50 offset and according to internet, that's what Rover recommends).
I've been looking at a few wheels, and some have 30 or 35 as a offset and I even found some with an offset of 60.

I know you can use a spacer to compensate.

What would still be a safe difference in offset? Would 35 still be perfectly fine without a spacer? Would 30 be waaaaaay to much?

ET35 puts the wheel center-line further out from the hub, with ET60 you'll need a spacer (10mm) to bring it back to the original ET50

Personally I wouldn't go further out than ET35 and with ET60 rims would bring it back to at least ET50 by using a 10mm spacer.

So no more then 35? Because I don't think you can fit something that will correct 35 to 50... (??)

I got 18" alloys running ET35 instead of the standard ET50. It brings the wheels out towards the arch. You can't bring ET35 back to ET50 unless you machine the inner hub face of the wheel.

The more you bring the wheels out (by reducing the ET) the higher the load on the front suspension and bearings will be.

Okay.... well guys... to be honest I just bought myself a few wheels...



They are 18", look great next to the car. (apart from the BMW logo which needs to go!)

But... they are ET20

To give an idea about looks at different ET values. From a beamer site but principle applies.

I know how the whole ET story goes , but thanks for the explanation.

I ended up buying them because I got a really good deal on them. I'm just gonna clean them up, give it a quick polish and put them on a second-hand website. An ET value of 20 is just gonna be WAY to much for the 75. I'll destroy my wheelbearings and such with it.

But I recall that they often say that a ET difference of +5 or -5 is acceptable, I kinda hoped that the Rover was so well engineered that they could cope with much more than that . However, an ET of 20 when Rover recommends 50 is kinda pushing it .

Not only that, you'd need a hub adaptor of at least 20 mm to correct the stud pattern so your offset would be 0
