All good points.
IF I can get a space saver, it's a no brainer. The LC500 comes with a jack, but no spare.
As for tyre gunk - I've not had great experiences with it. As for runflats, they won't handle a heavy impact on a pothole.
I've contacted Lexus UK to see if they can recommend something.
Question to you all. The tyre widths front and back are different on the LC. Are the actual wheels different?
Also, does the stud pattern ressemble any other Lexus vehicles e.g. LS?
