Hey guys, I'm looking into getting some new wheels for the upcoming summer and I am a complete amateur when it comes to fitment. The current wheels I have are 8.5j 19' ET45 with 235/35 tyres. I do want to stick to 19's but for some reason 9.5j ET35 with 225/35 has just popped into my head. I would like the wheels a little wider than 8.5 and with a little stretch, but I have no idea what I'm doing when it comes to this sort of thing and have no idea what the crack is with 'offset'. I have normally gone with what the chap says at southwest tyres when I have previously purchased wheels. Can I please have your input of what you think would be best. Thanks.
