Expect Ferrari and Red Bull, as well as Mercedes teammate Valtteri Bottas, to go flat out to make him wait at least until Texas, the following weekend, to step closer to Schumacher's record seven titles.
Sole rival Bottas is 64 points behind and Hamilton needs to score 14 points more than the Finn.
That means a podium finish as the bare minimum if the 34-year-old is to seal the championship with three races to spare, and history suggests that will be no easy matter.
Australia's Renault driver Daniel Ricciardo, meanwhile, hopes to build on his sixth-place last time out at the Japanese Grand Prix at Suzuka.
"Japan was quite a crazy weekend, so to round it off with sixth place from sixteenth on the grid was awesome," Ricciardo said.
"We've been on a disappointing run recently so we deserved the result in Japan. We're aiming to carry some momentum now in Mexico."
Hamilton has not finished in the top three at F1 highest altitude circuit, the Autodromo Hermanos Rodriguez which stands at 2,285 metres above sea level, since he won there in 2016.
"I think Mexico is generally our worst race of the year because of the way our car is set up and it's going to be a tough one for us," he said after the Japanese Grand Prix.
Team boss Toto Wolff agreed: "The four remaining races are not going to be easy and we expect Mexico to be the most difficult one for us."
If the champions struggle in the thin air, as they have for the past two years, then Ferrari and Red Bull can scent an opportunity.
Red Bull's Max Verstappen is chasing an unprecedented Mexican hat-trick after winning in 2017 and 2018 while Ferrari's Sebastian Vettel and Charles Leclerc have started the last five races on pole position between them.
Since Mexico returned to the calendar in 2015, the winner has always come from the front row.
Last year's race ended without a Mercedes driver on the podium, while Hamilton was only ninth in 2017.
