spare wheel mount for boost

I have just bought some boosts for my 110 but when I came to put the new spare on the back door I found it wouldn't fit the carrier already there which had the old steel wheel on it. The carrier fitted looks like this;

and the U shaped bar in the middle is too big to fit through the centre of the Boost alloy. Can I just take the door card off and unbolt the centre U shaped bar and use the three nuts to bolt on the boost or do I need a new carrier? Long term plan is to get a swing away anyway but sods law says if I leave the spare off I will get a puncture. The old tyres are 235/85 and the new ones 265/75 so don't think I could use the steel spare.

When a Boost wheel is used as a spare on a Discovery 1 it is held on to the carrier with just the three studs. So I don't see why when the U part of your carrier is removed the wheel can't t be fitted just using the remaining studs.

The rolling diameter of a 235/85r16 and 265/75r16 are near enough identical, so would guess that if the steel spare was good enough for the 235/85 then it should be fine for the 265/75 too

Cheers gents. Thing is, which I didn't mention for fear of appearing vain, is that the steel is tatty and the boost looks ace!

The u shaped bit is there to help support the weight of the wheel due to the flex in the studs.
I’ve seen disco 1 type carriers on the back door of defenders which would hold the wheel more rigidly.

Would not the width be a defining factor with regard to using the steel wheel ???, when the tyre width is changed, not the wheel diameter.

Like this-

Dunno what you would have to do to the door to fit it though.

Paint the steel ... easy ...

Once tight the wheel is supported by the back face of the wheel pushing on the mount plate. Simply remove the u shape bit and crack on. Mine was like that for eight years with no problems.

Another vote here for just removing the U shaped peice. Although I would be worried about the weight of any wheel that size on the rear door, and would look at a swingaway.

Not sure of your point exactly. Was merely pointing out that if the steel spare was OK for use with 235/85 then the diameter of the 265/75 tyre is pretty much the same. Bit like a space saver spare on a car is alright to get you on your way again.

The point is a bit redundant if the OP wants an alloy as a spare though

Realised what you were getting at after I had replied. I meant to use the current tyre on the steel wheel as a spare, not change it for the 265.

My point was , that even if the diameter is acceptable, then width of the rim may not be acceptable to allow the use of a 265 if it has a 235 fitted. Wheel widths change when the tyre get wider.

Sorry I figured that after I'd replied, I added a bit on the end of the last post.

I was just suggesting to use the steel spare with the original sized tyre as a spare, bit like a space saver on a car. Not swap to the 265.

Luckily found a mate with a swing away carrier going spare in return for a few beer tokens so will be fitting that when it warms up. Thanks for all the advice, much appreciated.
