From their info pages.
Thanks for the information. In each case, the wall height is greater than the tread width meaning they are both (just) the opposite of low profile. But, as pointed out, the Blockley does have a "low-profile" look - and exceeds a 100% profile by a smaller margin than the Longstone.
Blockley wall height = 3.975". Tread width = 3.7". This gives a tyre wall height 0.125" less than the tread width = a profile of 90.4%
Longstone wall height - 3.665". Tread width = 3.6". This a wall tyre height 0.065" greater than the tread width = a profile of 101.8%
Whatever the literature says, in Hedd's picture the Longstone looks to be taller in wall height than the Blockley.
Optical illusion or perhaps very worn Blockleys?
You are correct - I transposed a couple of numbers and the correct calculation is shown. A picture is worth a thousand times an incorrect calculation!
