Sick of expensive tyres brand not sticking to there sale pitch and story’s to get ppl to buy

Shocking tyres I have sp sport maxx TT My complete inner sidewall has bulged or bubbled the whole inner wall now i drive a 4wd car i can’t just replace 1 the have less than 2000k on them now i have to buy 2 or 4 this is disgusting the whole inner side wall damaged no signs of hotholes nothing why is the Tyres dining this I’m so angry it’s going in for a test they better replace all 4 with better tyres my kids could have been in the car that I’m sure in a manufacturer error I hardly drive the car. Should this not get sorted out SocialMedia is a big platform this tyre is so dangerous and the not cheap 4wd car no ill have to look at getting 4 tyres I really hope and pray Dunlop do the right thing and replace all 4 with better tyres!! Should the tell me i will have to buy new tyres I’ll make sure I tell everything to everyone I know. Test at 9 am hopefully they can see manufacturers error and replace them all,
