I bought 3 pairs of Dunlop steel-toe workboots in the mid-1990's, because they were going out cheap. I didn't need them immediately, but I thought I'd "stock up" for when I did need them.
I never even got to wear them. Within about 18 mths, the rubberised soles had turned into a gooey globby mess, that just fell off the uppers.
So I ended up with a set of 3 perfect leather uppers with no soles. I kept those new uppers for ages, thinking I might be able to organise new soles of some type for them.
No bootmaker would even look at them, so the uppers laid around my workshop for years, until I was evicted from it, ahead of workshop demolition, in early 2024.
So they went in the bin, in the huge cleanup associated with the move out of the workshop. What a bloody waste. I know now, why they were going out cheap.
Dunlop carried out some disastrous product moves in that era, and it still dogs them today. No Dunlop tyre I have ever bought, or acquired, has reached its full life without carcass separation, or just blowing out.
I just disposed of the last of 4 Dunlops I acquired on 4 wheels I bought to fit my Hilux about 3 years ago. They were almost new when I acquired them.
One separated within about 3 mths, another separated about 6 mths later, and the third separated about 6 mths after that. They just went completely out of round, developing huge carcass distortion.
The last one nearly wore out, but the tread started coming off on the inside, and that scared me a bit, because it was on a front wheel. So I ditched it for a new Bridgestone A/T697 Dueler.
I haven't actually bought any new Dunlops for about 40 years, I refuse to buy them. But I keep "inheriting" the darn things when they come on vehicles or wheels that I buy. They are total rubbish.
