2 years ago i bought 19" RS6 reps with "Clear" 235/35/19 tyres, although they have worn nicely and are a reasonably good handling tyre i have found them all to have hair line splits on the inside walls, is this something that could of been avoided like correct pressure etc.. or is it because they are just a low quality tyre with wrong load rating?

have looked at Falken FK452 on a wheel package I'm eyeing up but worried I may have the same issues 12 months down the road..

anyone with any similar issues/stories?
