Thank you all for your comments and help. Several options to consider but I'll go for having the rim seals checked first as it sounds as if that'll sort out the problem. Thanks again, guys.

Anyone else experiencing what seems to be porous Speedlines? All four tyres lose up to 8psi pressure weekly, which started a couple of years ago with one wheel and a couple of pounds pressure. Puncture and leaking valve checks drew a blank and replacing a couple of tyres made no difference at all. Any suggestions for a solution as I'm concerned that one or more tyres could suddenly lose all pressure? My VR6 must be one of the last, registered Jan. 1996 and is on the standard/original 5-spoke "star" style Speedlines
