Assuming the wheels are an Audi fitment and still 5x112PCD?
As JV says, they'll make your speedo slightly out and will physically be larger due to the 40% sidewall will be a fair bit taller on a 245 than a 225 which means that there will be less room under the arch in general.
I'd think a test fitment would be needed to make sure nothing catches but I reckon they'll be just about ok. That's quite a fat tyre for a Golf and if it snows heavy there won't be a lot of room in the wheel arch for snow and tyre.
Welcome BTW.
