Mad Town's Jota is stronger than Kang Ho Dong?

On KBS's 'Our Neighborhood Arts and Physical Education' on August 2, the members went to see the athletes at the place they work out and practice.  There, they saw a heavy 300 kg (~ 661 lb) tire that they would push upwards.

First, Kangnam, Jota, and Yoon Hyung Bin tried to pick up the tire, but it did not move, so they all gave up except Jota, who tried to pick it up by himself.  Clearly exerting a lot of strength, he ultimately was able to lift and push up the tire, surprising everybody.

Here, Kang Ho Dong joined the group late and made his own attempt, but failed.  Jota showed how he did it, lifting the tire once again to shock everyone a second time.  Taken aback, Kang Ho Dong said, "What are you?" and tried a second time.  This time, he managed to lift up the tire!  Looks like he's still got it.
