Allies have more side upgrades for infantry that cost fuel. Unless you skip all of these I would say Allies can get a tank out at a comparable level as Axis.
IF you can get away with skipping these Allies can get a tank out in a comperable time. None of OKW's side techs are necessary you can just skip them. USF you must unlock weapon racks and you must unlock grenades, and you must buy an ambulance. You can't skip any of those before teching to Major or your infantry will be easily out matched by OKW.
