The idea is to be as close as possible to real speed so coding it definitely helps. A slight variance is one thing (2 km or say less than 3 mph). 10 km/h or 5 miles or higher as standard is definitely off for most to accept. Personally I like to have it that what I see is actually what I am driving.
Agreed.

Your might've missed my point, though (or not, just clarifying ): the increased tire width implies a larger tire wall which increases rotational circumference and inadvertently brought the native speedo much closer to actual speed.
