2026 Auto Zeitung 18 Inch Summer Tyre Test
The Tercelo Sport D1 is the cheapest tyre in the test by a wide margin, but the results show why. It finishes last overall, scoring poorly in almost every area. On wet roads it has the least grip reserve in corners of any tyre tested, breaking away from the intended line early and reacting sharply to any lift-off or braking input mid-corner, with the rear stepping out aggressively and requiring large, fast steering corrections to catch. This kind of behaviour is demanding even for experienced drivers and could easily lead to a loss of control in an emergency situation. Wet braking distances are also long. On dry roads the tyre manages a passable handling lap time and the braking distances, while extended, are not dangerous. However, it also records the worst rolling resistance, the highest abrasion rate, and the lowest predicted tread life of all ten tyres. That last point is particularly damaging to its value proposition - the short life expectancy means the low purchase price doesn't translate into low running costs. The testers concluded that buying this tyre does not represent good value despite the initial saving.
