air leaks from tires

[W. Wells]

I have a SC430 with BBS rims. Lately air has been leaking from all four
tires. I asked the rim man and he suggested the pressure monitors in the
stems may be worn out. He said they usually last 10 years at the most. He
suggested to replace them rather than put in a rebuild kit. Any info from
other owners?

I think you should inflate the tires to the maximum indicated on the
sidewalls and submerge them in water or spray with a dishwasher detergent
and water mixture to find the source of the leaks. It is possible that the
wheels are porous or that leaks have developed where the bead meets the rim.

This is MY guess... 'cause I have been through this (they can be ground
smooth again). I have the most problem with the pair mounted in the front,
where all the weight is. Also 5/lb over recommended coupled with long trips

500mi, seem to seal things up for a while.

Normally 5 pounds over recommended is fine, but on the wide, low
profile OE tires (Dunlops in Canada) this is too much, and you will
find that the center of the tread will wear significantly faster than
the outside. 10-15% less life on a ridiculously short tire life just
adds insult to injury. :-)

how old are the tires?

Have the stems themselves ever been changed? They are unique to Lexus'
with tire pressure monitors and are a separate part.

Ask the shop to put each in the tub they use to check for leaks. You
should be able to tell exactly where it's leaking from.
