AMT Custom slicks in UK?

[Gelfin]

I'm new to car modeling and would appreciate some help. Bought a 68 Dodge Charger, Revell. The only thing I am strugglin with is to find AMT tyre sets in the UK. The stock tyres are 7.5" & are just a bit thin for my liking. I've been hunting for some wider rear tyres, but not pro-street. Can AMT sets be found in the UK, or (here's the Q) where do u guys shop for muscle car tyres. I've been shocked by USA postage costs, so where do u guys buy from?

Any help would be appreciated as I've been trolling the web for two weeks with little success. The build is progressing & I will post it soon, but my undercarriage is waiting on tyres to continue. Thanks G.
