I have 20,000 km Ultrac Vorti 225 45 ZR 17 XL 94 Y tires and I am very happy with them, the car is on the road like a train on a rail. The tight curves, the winding roads, are a delight. ABS rarely enters the limit, ESP rarely enters, in corners it rarely creaks at the limit.
The combination of a relatively heavy car ~ 1600 kg, sports springs Eibach Pro kit, these XL tires is a success and I recommend it.
After 20,000 km, the tires are like new, although I didn't turn them, I think they have a wear of 1-1.5 mm. I didn't measure their wear but they are like a new tire.
To make a summary, on my part it gains the maximum grade at the acquisition price, handling, stability, traction, braking, wear.
It loses an important point in noise, starting with 60 km / h it starts to be heard, at 100-130 km / h it is already at the bearable limit (for my ear), if I exceed this limit it starts to bother me the sound produced when driving.
Due to the noise, I can't give them the maximum grade, but at the same time I recommend them to anyone.
We were able to compare using the same car these Vredestein Ultrac Vorti tires versus Continental Premium Contact 5 used ~ 20,000 km, Sport Contact 5 used ~ 20,000 km and GoodYear EfficientGrip Performance used ~ 18,000 km.
