Wheelbase 777-300 A340-600 747-400

Hope you don't mind me popping over to this forum for a question.

Is the wheelbase length significantly longer on the 777-300 and 340-600 compared to the 747-400 or 747-8.

I noticed that in YVR that there is a taxiway turning restriction for 777-300/A340-600 & larger aircraft but then there are separate taxiway restrictions specifically for the 777-300/A340-600 only.

The last two times in YVR, they have given taxi clearances in violation of restrictions for our aircraft size.

Further discussion has brought uo the possibility of restrictions for 777-300 and A340-600 on taxiways based on a heavier footprint by these aircraft.

Thanks for the help.
