Didn't you post this before? And I answered it? And the thread disappeared. Or am I hallucinating?
Anyway the tallest appearing sidewall is the Avon SM MK 2 in the 5.00x16 size. Firestones are also available.
The 5.10x16 tires are actually low profile tires and are shorter than the 5.00x16 size.
Hope this helps.
