Hey!!

So classic new driver.. Mis judged the curb and hit it. Tyre damage on the far side front wheel. Was going no more than about 10mph as was turning around having gone the wrong way (Newbie!)... So the damage is on the sidewall of tyres that are less than a month old... I don't drive long distances oftenbut will be driving about 60 miles this weekend. Need to know if i need to get the tyres replaced beforehand. I know that when you replace on tyre you have to replace them all i think if i'm correct... Im not 100% sure... Have put two pictures up...

Is this okay do you think?
