So probably due to having gone over too many ridiculous Queensland road craters in the last 6 years, one of my rims has cracked and the tyre isn't holding air.
In short, it's fucked and needs to be replaced. Current rim spec is 18" 7.5" width, +48 offset. I'm having trouble finding just a single matching rim to replace it and I'm currently running my spare (I bought 5x of the same rim originally), so if I cop a puncture now I'm up shit creek.
What is the spec of the stock Spec B 18" rims (I have a 2005 non-spec B 3.0R) and is it likely to cause problems if I use one of these (or some other wheel) which doesn't have the same offset and width as a spare?
