The short answer is nothing. Italy still has those crappy mountain passes and valleys all pre-ranged with heavy artillery, mined, and covered by some damn good guns. Even an M1A2 Abrams wouldn't make it through one of those hellholes.
D-Day doesn't happen any earlier, and the 90% infantry force facing the Western Allies still fights like hell, still bleeds the Allies in Normandy, and Market Garden, and the Hürtgen, and at Aachen, and any other chance they get.
Hell, it's possible some Allied offensives actually do LESS well. Cobra in particular would be a lot easier for the Germans to counter with a third fewer Shermans.
Secondly, Wacht am Rhine might go better for the Germans. There would be fewer operationally mobile armored units to throw in their way.
Your heavy tanks do nothing in particular to affect the basically non-existent German tank forces on the Western Front. Fixed defensive positions are few and far between.
