alloy wheels fitment

[geeman]

While were on the subject of wheels, i found a set of 15 in alloys near me for aout £150, but the seller has only told me thay have come off a peugeot 106 so it has a bigger bore(65.1mm) and a offset of 20mm(i think) which im not sure if would be suitable?

if not, i have found many other alloys mostly which are 17in ones. I know that for optimum geometory, 15 in alloys are required, but would i encounter any problems using bigger wheels?

Thanks.
