Here at Tyre Reviews, we receive many different questions about tyres, but one question that comes up more than most asks if modern retreaded tyres, sometimes called "retread" or "remoulds", any good?
While we've not been able to test ourselves, tests from many years ago indicate that retreaded tyres don't perform as well as even a budget tyre. Car tyres typically aren't designed to be retreaded (commercial bus and lorry tyres are), so the retreading process can leave you with not only poor performance, but a product that could be classified as unsafe.
Naturally in the past few years there have been improvements in the car retreading process, and one brand in particular, King Meiler, has established a name for itself as "the" retreading brand.
To find out whether a modern retread can match a premium, or even a budget tyre, the Polish magazine "Motor" have tested the King Meiler HPZ against the premium Continental PremiumContact 6, and a much cheaper Debica Presto HP.
The results speak for themselves.
Dry
It's been a while since we've seen such huge differences in the dry between a premium tyre and a brand like Debica, which indicates that this version of the Presto HP certainly isn't the grippiest tyre on test, so for the retreaded tyre to be so far behind in both dry braking and dry handling, indicates a serious lack of grip!

Wet
Wet was a similar story to dry, except with larger margins. While the Debica stopped the car a pretty sizable 6.3 meters after the premium Continental, the King Meiler took a HUGE extra 24.3 meters to stop the car, again from 100 km/h. This means, where the car on the Debica stops, the car fitted with the King-Meiler tyres will still be doing more than 48 km/h!

The retread tyre also performed poorly in straight aquaplaning.

Environment
With the retreaded tyre both noiser, and less comfortable than the premium and budget tyres, its only positive quality was price. However, with the longevity of the tyre untested, is a 100 euro saving really worth all the negative qualities?
