Vredestein Ultrac Vorti 270/35 R18 BMW 530i M Sport Touring 250 miles April 2, 2020
Superb tyres; as good, if not better, than the likes of Eagle F1s and PS4s in my opinion. Having gone through various tyres in the past on previous BMW saloons 9E38s and E39s); I've always found they can handle very differently on tyres; better on premium tyres, but not much better than excellent mid-range tyres like RainSport 3s and Vred Ultrac Vorti's. I've also found the likes of the PS4s gert very hard and drone a lot when they're through the first 2-3mm of the softer rubber. For me, it's very noticeable and it goes against them. Having run 18 and 19" alloys and tyres on my previous BMWs; I've tended to always go for the RainSport 3s or Vreds; unfortunately Uniroyal don't do the rear sizes I want (I run 245/40 and 275/35 18" tyres); I could have gone to the tried and tested Nexen N'Fera SU1s, which again, I find to be an excellent tyre, about the best of any 'budget' tyre out there IMO. But, I wanted to go 'premium' but without the premium price, so I went back to the Vredestein's and do not regret it one jot. Excellent grip both wet & dry, superb handling, a slightly stiffer sidewall, so excellent feedback and smooth/quiet/comfy to boot. Highly recommended
