Big brake spare wheel

With my upgrade to xc90 brakes on my 740, the spare obviously won't fit anymore, any suggestions?

I bought the xc90's spare, but it's 155/85r18, much bigger than my 225/45r17's, I also saw the s60 ones which are 125x80R17, still a bit big.

Anyone else running the 336mm setup?

buy a 12v compressor and deflate it?

I have that V70II/S60 17" spare. While the true size of stock tires varies between manufacturers and models, the spare diameter is close to the calculated diameter of a 225/45. If you are worried about the difference with a LSD, I would just swap the front wheel to rear and use the spare only in the front.

Alright great, I'll try to get one of those then, I own or of those compressors, so I might deflating it a bit a try as well!
