Hi guys,

Ive got standard 18" alloys on my s3 currently, thinking of potentially upping to 19".
Does anyone know what size tyre fitment would best suit 19" alloys to keep the speedo as accurate as possible?

Im thinking going for 30 profile with the 19r may keep it relatively close to the standard, i currently have 225/40/18.

anyone had any experience?

225 35 19
