Right, I have an 06 E90 320D running 16" wheels all round Ditched the RFTs ages ago and rolled with a can of gunk in the boot until now. After 2 failed attempts using the gunk I have decided the only way forward is either go back to RFTs which i am not keen on the idea although the best tyre I can see is the Goodyear efficient grip RFT coming in at £95 per corner. I currently go for the same tyre in non RFT which are just about £30 cheaper, more fuel efficient & have better wet grip. However its gonna be a trade off as I will lose a fair portion of my boot if i buy a spare. If I do go the spare route what size would I need to buy for it to properly fit my car? I could however creat a false bottom of my boot so that i dont lose the floorspace, just depth from floor to top. Thanks Andy GoodYear Efficient Grip RFT GoodYear Efficient Grip
