Warren Gatland’s men take on the South Sea Islanders with Tipuric one of only four players to retain their place from last week’s comfortable victory over Argentina.
Leigh Halfpenny, George North and Rhodri Jones are the others who start again, Tonga set to provide a typical South Sea Islander test.
“I played against Samoa last year, luckily enough I didn’t try running straight through them as I’m not the heaviest,” said Ospreys flanker Tipuric.
“All the Pacific Island teams are physical and watching a few games from the weekend, it shows they put their bodies on the line and don’t leave anything out there.
“When you play physical games in international rugby you don’t just ache for one or two days, you ache for a week. We’ll try and take their strengths away from them and attack their weaknesses.”
With 11 changes in all, there are plenty of men in the Wales side determined to impress on Friday. Tipuric remains on the openside flank with Andrew Coombs and Ryan Jones joining him in the back row. The latter leads Wales for the 33rd time.
“It’s a fresh challenge for some and we just want to keep winning which is the main thing,” said Tipuric.
“We’ve got a target to win three out of four and we’ve got to do that.
“Andrew’s playing really well this season, it’s a chance for him to impress this weekend. He’s played blindside so much over the years, I remember playing against him in the Premiership when he was at Newport and I was at Aberavon.”
On Jones, his regional teammate at the Liberty Stadium, Tipuric added: “Ryan is a natural leader. He’s been great for me over the years, coming through the Ospreys I’ve been able to learn a lot from him. He’s a great guy and thinks about the team and not just himself.”
After dismissing Argentina last Saturday, Tipuric is set to feature for Wales for the third consecutive weekend against a Tongan side who were beaten by France last time out.
“You’ve got to keep your head but at the same time you can’t take a backward step,” Tipuric said, as he previewed Friday’s encounter.
“Playing for your country is great and to do it three times in a row is pretty special.
“As long as we’re winning I’m happy but I don’t think I’ve ever had the perfect game and I always push myself to keep improving.”
