June 2023 UK technical sheet
Selected wheel packages in the dated Lexus UK technical sheet. Front/rear and F Sport differences must be preserved. Where the source uses RF, its run-flat construction is stated in the variant column. Lexus describes these sheets as media guidance; verify the exact car with a Lexus centre.
Check your exact vehicle. These are selected documented combinations, not a registration lookup or a complete fitment list. A tyre with the same size can have a different load index, speed rating, construction or manufacturer approval.
