just out of interest, i went and had a look this afternoon as i was reseating some bfgs a friend that were leaking round the rim , and looking at modular rims /land rover alloys and old series riveted rims i honestly cant see that much of a difference on the bead seat so i stuck a tubeless tyre on an old riveted rim and it seated fine, mind you that was with a compressor might be different with a foot pump it sealed and wasn't leaking i'll see what its like in the morning
