After the PS3 and the PSS, I trust that Michelin can combine the best of both. Tire tests vary too. So far, 1000miles in with 235/40R18, certainly not regretting my choice so far, good and progressive grip, good steering feedback and not uncomfortable either. 300hp fwd car.
Thanks for the feedback, we look forward to hearing another review after more miles! :)
I cannot believe that 6 months after the PS4 came to market there is no single test where this tire is compared to competitors; makes no sense that non of auto sport magazines is not able to obtain it..
We believe Auto Express and EVO magazine are testing it in their tests this year, however their tire tests aren't usually out until later in the year.
How late is "later"? I´m also interested of a review of the new Yokohama Advan Fleva V701 and new Pirelli P Zero PZ4.
And I agree with Santorini11, I have this magazine and the conclusion of the PS4-"test" is like a feeling, not a objective result. And they wrote taht the PS4 would be in the top 3, this sounds to me like it would be the 3rd, but is the most expensive tire
Vredestein really seem to be letting things slip of late, their once strong performance has faded and the wet grip is increasingly being reported as poor... The delamination is not good! A bad batch is always a possibility but someone like Vredestein should have the quality control in place to ensure it doesn't.
Things seem to have slipped gradually since apollo bpught them, i wonder if the asian company are penny pinching and cutting corners while syphoning the r&d for their own tires...
Vredestein is here (Germany) most known for good snow tires, but summer tires? I drove some Vredestein many years ago, in the wet it was not really good and after some years the rubber was hard like stone.
Vredesteins winter tires are also not known for good performance on the wet, the Snowtrac 5 don´t made it to the final 18 of 50 tires in Autobild 2015 because the wet braking result was over 44m.
The Ultrac Vorti have very hard sidewalls, looks like it was hard for some tire dealers have a problem to fit it on the rim or damage it.
