but if the rims are wider surely that offset wouldnt be the same?
i.e ur adding an inch to the width of the rim so u need to reduce the offset?

not sure really whether they do it without telling u?
best to ask them for a price and wot offset ud get
end of the day it'll prob rub either way!

my theory is if ur fitting a rim that is an inch wider, would u need to get an offset of say et13 to position the wheel in the same position?
1inch = 25.4mm
or am i throwing the plot away?

basically to work out the offset of a wheel you split it in half (width wise) and then measure from the halfway line to the back face of the wheel that would meet the wheel hub. This number will be referred to as ET and the cupra's recommended ET for a 7x17 is ET35 to ET38. As a rule of thumb you can normally move +/-5 either way so if you car was recommended to run a ET38 you could fit a wheels that ranged from ET33 to ET43.
What confuses people is that as wheel diameter increases the width will generally also increase which will obviously increase the distance from the centre of the wheel to the back face of the hub.

Use this calculator, type in your current wheel stats and the stats of the new wheel you want, and it will tell you exactly how much clearance your new wheels will leave you with. Easy.
