Pass. Like I said, there are so many options these days for tyres and rims it just confuses the hell out of me. I know the exchange rate isnt great right now, but we do still get ~$1.40 for every £1, so its not that bad really- concidering UK prices it is still possible to import stuff and save money, or at the very least not loose out compared to buying from a UK shop/ online store; whatever the USA $ price is, swap the $ for a £ and thats about the price it is/ way it works out, so importing aint that bad, just gotta hunt out the bargains on the larger stores like tower or amain etc.
There is always ebay however, or the old wheeler-dealer-pirate-importer-ask an American buddie to buy it for you and mark the value lower then send them the money- method of getting goods from overseas... (works for me

)...
