The proper torque for your lug nuts is listed in the owners manual given as a range. Apparently tight is good enough, however I torque mine to 80 ft/lbs because thats where my tire installer recommended. This figure is also within the given range.

Here's the link for the above mentioned service bulletin:
http://www.finishlineperformance.com...02-002-04.html
More important than the actual number is: 1) torque in star sequence (same as going around the wheel every other lug at a time), and 2) torque all lugs to the same value.
A decent 1/2" drive click-type torque wrench can be bought at Sears or other tool dealer. One such tool is:

"Verify customer concern."
No ticking - no concerns here!
I wonder if Mazda follows higher wheel torque range for all customers or just ones that complain about the ticking since this is not a recall?
I'll have to ask next time I go in for service.

I hate to ask this, but since I don't know the answer:
what type of socket is required to mate up to the 1/2" drive torque wrench when torquing our wheels? TIA

only about 14mils different.
I use a deep, 6-point 13/16" socket. I like 6-point because it lessens the chance of rounding the lug. Depending on how deep the socket is that you buy, you might want to pick up a short 1-2" extension so that your wrench clears the fenders when torquing the lugs.

well, 'cause this car is manufactured in japan with standard japanese fasteners, it's supposed to really be metric sizing for everything... but as you said, 0.014" isn't a huge difference, and if your 13/16ths is (really) well used, it probably squeezes on there ok.

At the risk repeating info already out there, always use a torque wrench on your wheels. Also, don't let anyone use an impact wrench to tighten your lug nuts unless it has the correct torque stick on it.
A torque stick is an extension that fits in-between the socket an the impact wrench. It prevents the impact wrench from tightening the lugs past a certain torque. It does that by flexing with each pulse of the impact wrench. At a certain torque, it's just going to twist back and forth absorbing the impact energy from the impact wrench.
Over tightening of wheel lug nuts can warp brake rotors, which is one of the factors that can result in that pulse we’ve all felt at one time or another through the brake, peddle.
Lastly, if they don't look like they know what they are doing, keep them and their impact wrench away from your car

appreciate the info. Will have to see what I can find. First I need a torque wrench to begin with. It is interesting the metric sizing. I've done the same math thing and one would tend to think the standard size wouldn't fit because it'd be too small. For some odd reason one of my socket sets is missing 13/16 and I have 2 3/4 - probably a factory error. I measured the inside of the lug wrench and it came up real close to 21mm - maybe an interior size of 21.5mm.

Just set mine to 108 per the TSB when I rotated the tires this week.
The standard lug nuts each took over 150 ft-lbs to loosen so I had to use a breaker bar. The locking lugs were on so tight I had to use a 2 ft extension on the breaker bar. The factory or the port must be using pneumatics set way too high.
Everyone might want to break their lugs free and then torque properly otherwise the first time the wheels need to come off someone might mess them up.
