I would have thought since the 430 was a bigger car it would have bigger wheels & tires. So they're the same diameter as the stock LS 400 wheels?
edit: Just looked up all the info on tirerack and you're right they're very close. the 430 set would have about a .1" taller diameter but that's negligible.
OE 99 LS 400 = 225/60R16.
8.85827" tread width.
135mm = 5.31496" sidewall height.
16 + 10.6 = 26.6" diameter
OE tires on 2005 LS 430 18 x 7.5" wheel = P245/45R18
245mm = 9.64567 inches 4.34055 sidewall height
