Driving a 204 HP and 400 Nm BMW with 245 width rear tires on the wet can be a serious thing. Even we careful driving, I can perfectly remember that two friends of mine had a disastrous surfing experience when their BMWs went into aquaplaning on the highway at, say a little bit too much speed, ... but not that much (140-150 km/h they said). That is when you destroy a nice car because the rear suddenly intends to take the place of the front. Bad joke. Hopefully no-one got wounded.
So of course, you will just slow down under the rain. BMWs are absolutely safe on the wet if you do not make the stupid assumption that you are above physics. Use them properly. However, when choosing tires for this powerful and heavy RWD car, my very first criteria of choice was aquaplaning and wet grip. I could not prevent reminding about the stories of my 2 friends...
This said, I was truly amazed by these tires under wet conditions. Their aquaplaning limit is high, even with a tread down to the 1.8 mm limit (time to change them !). And the wet grip is just awesome. Press down the pedal and get the 400 Nm down to the rear wheels, it is quite tough to force the ASC system to get into action, even under very adverse rainy conditions. Truly impressive. I felt 100% safe during the whole lifetime of these tires, which, again, was the most important thing for me.
These Uniroyal tires did not disappoint me under dry conditions either. There are not sporty but they grip very well, with pretty good feedback. They are quite silent. Overall I thought they have made a good fit for my BMW E46, which is not a sports car, but a comfortable and fast (and too heavy) machine.
Now the wear rate. True, it is quite high. But it was not dramatic on my BMW touring either, in spite of regular fast driving in the mountains. The Rears made 28-30 thousand kms (down to the 1.8 mm limit). This is not a great mileage, but the price of these tires is very attractive (90€/ tire) , and the reviews will tell you that some very expensive tires do ALSO receive some criticism on wear rate in spite of prices up to 140-150 €.
Overall the balance is still pretty good.
Let me reformulate this: I guess this is OK... if you do not drive more than 25 000 km a year. Then above that mileage, it is probably unpleasant to change tires every 8 to 10 months...
Just bought another pair of rear tires, with a smile, for 185€.
