There are numerous guides on internet that explain offsets This is very simple one....
http://www.raceandroad.com/technical-help/alloy-wheel-offset.html The problem I have had in the past (not on an Extreme) when I got the rim width size and offset wrong was that the wheels fouled on the suspension. I would sketch out the suspension, hub, wheels and wheel arches on a piece of paper and add in the dimensions for the reccommend set and then do the same for the wheel rims you are proposing. This should give you the offset required and show if they will fit in the wheel arches and still be clear of the suspension....

(before my tiny little brain goes pop!) I recently had the euphoria of getting my Xtreme through the IVA and swiftly moved my thoughts to getting all the bells and whistles added. It seems that nothing is straight forward but after much headscratching I have sorted everything but the alloys which are causing me a real headache (mostly due to my lack of knowledge). I'm banking on others having either been through the same situation or just being alot smarter than I am so that I can get advice to ensure I get the order right (its too much money for me to get it wrong). I currently have the Sierra donor wheels on. These are 14" rims with 185-65-14 tyres (curiously this is not one of the wheel/tyre 'options' in the build manual) and while I cant find markings on the wheel I believe them to be 6" wide with the Sierra standard 35-38 offset. I contacted Quantum to seek their advice and they duly responded with the reccommendation to fit 15" x 6.5" rims with 195-50-15 tyres and a 25 offset. Unfortunatly the wheels I am buying are 15" x 7", but this size with 195-50-15 tyres is an option given in the build manual, so should fit ok as long as I get the offset correct. This is where my brain begins to ache! The wheel manufacturer is offering the following offset options (ET15, ET19, ET20 & ET23) and while I understand the need to potentially change the offset from the Quantum recommendation due to the extra 0.5" width of the rim I'm struggling to work out which option is right, especially as the current wheels seem to fit the wheel arches fine but I don't know there exact specification for comparison. I am also wary that if I get it slightly out in one direction I could compensate with a spacer (although this could cause additional wheel arch fouling problems) but if I get it wrong in the other direction there is no chance to correct for it.
