Private,
While most people do not own a tire tread depth gauge, they should
undoubtedly have access to a penny. The penny is a simple (and cheap) way
to supplement visual inspection of the tread wear indicators.

I do not disagree, the point I was trying to make is......
Tires are a very important safety critical item and deserve careful
attention to maximize safe operation. They are a costly consumable that is
second to only fuel and aprox equal to oil changes in total cost. This
significant cost can be minimized by careful monitoring of inflation and
wear and by frequent rotations. Tire maintenance does not require extensive
experience or significant time and is well within the capabilities of most
any car operator. Tire inspection and rotation does not require a
significant investment in tools nor does it require a workshop. The only
tools that are required are a quality tire pressure gauge and a tread depth
gauge, both of which can be purchased for $10-25 total, a second set of 4
rims will cost $20-150. These small investments will easily pay for
themselves during the service life of any car and normally much sooner.
Many people will claim they are too busy and prefer to have tire maintenance
performed by others at time of oil change but I submit that DIY will be both
cost and time effective and give the added benefit of allowing inspection of
brakes, suspension and exhaust systems at the same time.
We both know that the primary cause of both tire failure and short tire life
is underinflation. I suspect we will agree that the most common cause of
engine damage is failure to check oil and coolant levels and that the
easiest way to obtain good engine life is frequent oil changes. Our cars
are a big investment and a substantial yearly cost, simple maintenance will
substantially extend service life and minimize total cost. IMHO depending
on others to do this maintenance leads to missed oil changes and
maintenance, depending on a garage or dealer to do all this work is IMHO a
guarantee of over paying for this work.
Good luck, YMMV
