Harry your reasoning is correct, but he's going to smaller rims so he will actually be losing an inch on the diameter "with about the same profile" which means his speedometer will read faster than he's actually going.

This was what I wanted to know. Really wont matter much cuz I won't exactly be speeding around in this truck anyway, but good to know I'll actually be going slower than speedo says. No plans on dropping a V8 in her.
