It was a forgettable day for the visitors, particularly given that they played the vast majority of the match with just 14 men after lock James Hamilton was shown the red card in the 16th minute.
Strangely, that sending-off had a galvanising effect on the battling Tigers, who played their best rugby in the immediate aftermath to give Leicester fans hope.
Having opened the scoring as early as the second minute with a penalty from Myring, Leicester struck with two quick-fire tries in the 20th and 23rd minutes, Sam Vesty and outstanding young openside Will Skinner going over for tries.
Tim Stimpson managed one conversion to enable Tigers to go in the break with a lead of 15-9 – Tykes having scored three penalties through the boot of former Scotland international Duncan Hodge.
But after the break, the Tykes – with Hodge to the fore – seized control of the match, giving the Tigers a torrid time of it and racking up 30 points in a devastating last 30 minutes of rugby.
Back rower Dan Hyde began the rout with a try in the 50th minute, Hodge supplying the conversion and then kicking a penalty in the 57th minute to stretch his side's lead.
While Leicester could muster only a single penalty goal from Stimpson in the 60th minute, Leeds cut loose, Ponton, Cardey and then Hodge going over for tries to hand out another defeat to the Tigers.
