tire question
Okay, I give up... how do you measure the remaining tread on a tire?
In the parts section I always see people with used tires with 5/10ths or 7/10ths tread remaining. How do you measure that?

Parts store and buy a tire tread gauge.

Two ways are possible. Some tires have wear bars, molded bars that span the tread but are recessed such that when they are exposed then it's time to reshod.
The old, tried and true penny method can be used in lieu of wear bars. Insert the penny so that Lincolns head is toward the tire. If the tread doesn't meet his hair, it's time to retread.

Tire Question
As a general rule measurements are in 32nds. of an inch. Most manufacturers consider the tire worn out when the remaining tread reaches 2/32 of an inch. You should be able to buy a tread depth gauge at any auto parts store. Tread wear indicators built into most modern tires indicate when the tire is ready to be replaced.

If you buy a used tire with 4/32 of usable tread left, then the tire has 50% of it's life left.

You can buy a tire tread depth guage at any parts store. Or, just go to a tire store and have them measure it.
