The　temperature　field　of　tires　has　a　significant　impact　on　the　cracking　aging　and　service　life　of　tires.　Therefore,　the　finite　element　simulations　of　the　temperature　field　of　the　mining　tire　were　carried　out　in　this　paper.　The　temperatures　of　the　key　parts　of　the　tire　were　measured　with　the　thermocouple　under　real　working　conditions.　The　deviation　between　the　results　of　the　simulation　and　the　measurement　is　1.3%.　In　addition,　the　function　among　the　maximum　temperature,　the　velocity　and　sinking　amount　of　the　tire　was　fitted　using　the　simulating　results　of　the　temperature　field　under　the　nine　types　of　working　conditions.　Further,　based　on　the　response　surface　method,　the　structure　of　the　1#　strap　layer　with　high　temperature　of　the　tire　was　optimised　by　taking　the　width　of　the　strap　layer,　the　distribution　density　of　the　steel　wire　and　the　angle　of　the　steel　wire　arrangement　as　the　independent　variables,　and　the　maximum　temperature　of　the　tire　under　steady　rolling　as　the　response　value.　Finally,　the　results　show　that　the　maximum　temperature　of　the　optimised　model　decreases　by　3.06 °C　compared　to　the　original　model.　©　The　Author(s)　2025.
