Valley Forge Automotive Center will remain open for another season. Netflix has renewed Tires for Season 4 only a few weeks after the third season arrived on the service.
The renewal is particularly notable because the series started outside Netflix's production system entirely.
A YouTube pilot became a Netflix franchise
Gillis uploaded an early Tires pilot to YouTube in 2019. He, McKeever and Gerben later financed and produced a six-episode first season independently in Pennsylvania.
Netflix acquired that season for distribution in 2024 and then began funding subsequent seasons.
Season 4 completes a fairly dramatic reversal. What began as a small project looking for a home has become a recurring Netflix comedy receiving another order before the current season has had much time to cool down.
Season 3 delivered the show's best Netflix performance
Tires has accumulated more than 45 million views across its first three seasons, according to figures released around the renewal.
Season 3 also reached No. 5 on Netflix's English-language TV Top 10, the highest position the show has achieved. Netflix separately reported that the season debuted at No. 3 on the US English TV chart with roughly 2 million views.
Those rankings cover different measurements, but both point in the same direction: Tires is still expanding beyond the audience that followed Gillis into its first season.
Netflix is investing in much more than Tires
The fourth-season order also fits a broader relationship. Gillis and McKeever signed a creative partnership with Netflix earlier this year to develop additional movies and television projects.
The deal includes two new Gillis stand-up specials as well.
Netflix is therefore treating Tires as more than an isolated sitcom renewal. It is part of an expanding partnership with a comedian whose live audience has also grown dramatically, including a record-setting stadium performance in Philadelphia this summer.
The show has kept its Pennsylvania roots
Despite that increased scale, Tires still looks deliberately local. All three released seasons were filmed in Pennsylvania, using real automotive businesses and locations across several towns and cities.
Netflix says Season 3 worked with more than 250 local vendors and businesses and shot in West Chester, Philadelphia, Phoenixville, Oaks, Frazer and Glenside.
That practical environment helps distinguish Valley Forge from the polished, anonymous workplaces that can make streaming sitcoms feel interchangeable.
Netflix knows exactly which audience it is serving
The series centers on Steve Gerben's Will, an anxious and questionably qualified manager attempting to improve his family's automotive business while dealing with his disruptive cousin Shane.
Gillis and Gerben are joined by Chris O'Connor, Kilah Fox, Stavros Halkias and Thomas Haden Church, with a growing list of comedians and actors appearing as guests.
Netflix US comedy chief Tracey Pakosta pointed directly to the show's unapologetic comic voice and its rising Top 10 performance when discussing the renewal.
No Season 4 release date has been announced yet.
The important part is already settled: a sitcom its creators once had to finance themselves now has Netflix paying for another year at the shop.
