Measure the tread depth yourself, in 32nds of an inch, and that's how much tread is left. (It's impossible to tell from a photo, unless the photo has a ruler or tread depth gauge in it.)

If you know the tread depth, and you know how many miles you drove on them to reach that tread depth, you can extrapolate to calculate the remaining miles. To do the calculation, you need to know how deep the tread is when the tires are new - that's 10/32" for the Michelin Pilot HX MXM4 - and how deep the tread is when the tires need to be replaced - we'll assume you drive them down to 2/32" when the treadwear indicator bars are flat across and the tires must be replaced by law.
For example, let's say you've driven 30,000 miles on them so far, and the tread depth is 4/32". That means you have worn 6/32" off the tread in those 30,000 miles, so the remaining 2/32" of tread depth before you have to replace the tires should last you around 10,000 miles.

Yeah, it's probably about that. It's not down to 2/32" yet. It's easy to tell when a tire is down to 2/32" of tread depth. By law, all street-legal tires have treadwear indicator bars, half-inch strips going across the width of the tread that are 2/32" shallower than the rest of the tread. When the tire is worn down to 2/32" of tread depth, these strips appear as flat across the tread. The indicator bars are visible in the photo but the tire is not worn down to where they are flat yet.
By law, you need to replace tires when they reach 2/32" of tread depth. However, when they are worn (but not yet at 2/32"), their traction in rain gets considerably worse, and you may want to replace them before 2/32". The Tire Rack did a test comparing braking distances for new tires, tires worn to 4/32", and tires worn to 2/32". They found that braking distances on wet pavement increased by about 50 percent for the 4/32" tires and almost doubled for the 2/32" tires. You can read the full test on their website here.
