The Hankooks fitted to our Lunar Delta were cracking after 2 years plus we had one side wall blow out with them. This was about 6 years ago and I had checked the tyres prior to leaving the site.
Much earlier about 20 or more years ago with Dunlop I had 2 side wall blowouts, now steer clear of them also. I was not the only one to experience this as all our company cars came with Dunlop tyres and the cars were checked every Monday morning.
However my choice as both manufacture's probably have improved by now.
