I am happy that thee are better tyres to choose from these days. I haven't tried uniroyals, but I did see a set in the garage and the sidewall looked a bit flimsy, but no idea if this helps.
The vorti pressures that I have are 38 (F) 34 (R), and this seems really good. Attack a roundabout fast and add a bit of power. I am very happy with the result and they are still not squealing.
I am super happy with the Vortis, more than I was with the sessantas on my A3. I really can't see how they could get better, perhaps maybe for economy.
It's your money, your choice.
