These tires were unfortunately fitted by a dealer when I bought a BMW 530D from them......
They are simply abysmal! In the dry they are ok ish (but most any tire would give some dry grip), however, in the wet, they are totally unpredictable,with no feedback, the only thing you can safely predict is that the wheels will spin incessantly (traction control or not)- and any corners have to be taken with a good deal of trepidation. In the hands of an inexperienced driver I fear that any car would soon be proceeding (probably sideways) towards the scene of a nasty accident. Incidentally, the noise from these tires is a constant reminder that they are total CRAP.
I cannot imagine that there could be a worse tire on sale. It certainly seems that you pay for what you get with tires, so do like I'm doing, and get a proper, branded set of tires fitted before it's too late!

Avoid these tires like the plague. I Recently bought a 3yr old Seat Altea FR Tdi which had these tires on the front and a set of Pirelli PZero Rosso on the rear. The Pirelli's are standard fit so I assummed the Triangles had been recent replacements. They were in good nick with plenty of tread so I decided to give them a chance despite having never heard of them and having concerns about budget tires on an FR. Very quickly I realised that the car was not handling or responding as I expected. I have use of a Leon FR of a similar age which is a great drive and handles brilliantly so I was initially dissapointed with the Altea. I did not have confidence in the cars handling and torque steer was terrible from the off. In the wet it was not an enjoyable car to drive. I never thought it would be the tires. 9 months later and the tires were worn to the point of needing replacing. I considered putting PZero Rosso's on the front too but have decided to go with Goodyear Eagle F1 assymetric 2's. The difference was amazing. The car now drives the way I would expect an FR to drive. It's early days but the Goodyears are impressing me all the time. Triangle may be half the price but they will last you less than half the time and will take away any driving enjoyment you have.
