England lost two players to the sin-bin in the first half and gave away a string of penalties but still managed to put together enough fluent spells to score four well-taken tries.
Tonks, playing at centre after starting the opening win over Italy on the bench, helped to create the opening score for Harlequins’ Chris York.
Hurrell gained a second successive cap on the wing, while Leicester scrum-half Sam Harrison was named among the replacements after being called into the squad when Ben Youngs returned to club duty.
