Quote from the guru of Land Rovers in Nova Scotia....
"NA spec series 3 came with H78 15 tires since in the early 70s 16 inch tires were like hens teeth this side of the Atlantic.
So the 225/75/16 would be closer to the H78 15.
the 7.50 16s only came on 109s with 6.50 16 fitted to 88s for much of the rest of the world.
If you have a NA series 3 88 the speedo will be calibrated for the smaller tire." -John Cranfield.
hope that clears things up, I assume that you are in the US?
