Bridgestone Alenza 001 RFT 

These tires came on my new BMW. I'd had Bridgestone tires before but not in an RFT. Was I ever surprised!!! I love these tires. Great high-speed cornering along with great stopping. I've driven high speeds in rains and not once did these tires hydroplane. I've stomped the gas pedal at stoplights during the rain and never spun a tire. Tis a shame that these tires are not offered in all-weather RFT tires with the 168mph rating. I'd buy them. They respond very quickly. Wear on them is great too. I am a stickler for tire pressures. I check my tire pressures several times weekly and if they're not at the factory recommended psi when checked cold, I make adjustments so they are. Due to the weather, I am now being forced to remove these tires and buy another tire that is all-weather instead of high performance summer. I'd gladly buy them again.

Tires came on a 2019 BMW X4 M40i. I must say that I am impressed with the car and tire combination. The stability and handling (wet or dry) is some of the best I have encountered to date. They are a little noisy and stiff but they are 20 inch low profile performance tires so I wouldn't expect anything else. All around a very well balanced tire. The only gripe I have about them is the hydroplaning resistance. Puddles about a half inch deep at 40 to 50 mph will send you all over the place. Overall, I would buy again but living in the PNW where it rains a lot, hydroplane resistance is a top priority for me. I haven't tried them in the snow yet but the recent freezing fog we had, they did well. Being that I have only put 2,000 miles on them I won't expect more than another 10,000 miles. You have to pay to play... Can't have a tired that does everything well and I'd rather replace my tires often knowing that the grip is there, vs having a more comfortable ride.

I really cannot complain about these tires since we dont have that many options to choose from. These tires have been great but would like to see some michelin tires available at some point. I did put 25k miles on the first set. I had them balanced every 6-7k miles. Now car has 31k miles total, so the new set has 7k miles, they seem to be wearing a bit faster than the first set, however no problems. Completed a road trip with a torrential thunderstorm for 500 miles and tires were solid, no hydroplaning at all. Will keep you posted as they eat the miles.

These tires came standard on my 2019 BMW X3 M40i with the 21" rims (245/40R21 front tires & 275/35R21 rear tires).
As you might expect, RFT sidewalls on such slim rubber results in a rather harsh ride. However, the tires are quiet and the handling is impressive under heavy acceleration and cornering. Sadly, they wear incredibly fast, and I'm on my second set of rear tires in about 24,000 miles (38,000 km), and they're nearly at the wear bars.

My front tires are another story altogether. I have had to replace 4 front tires due to pinch flats resulting in herniation of the sidewalls due to hitting potholes. One front tire was ruined when driving 30 mph and hitting a pothole. It bulged the sidewall. A second time we hit an unmarked cut across the road due to utility work, again at about 30 mph, and both front tires ruptured their sidewalls and blew out! Our X3 had to be towed on a flatbed. Our third episode was a pothole on the freeway at night, resulting in another blow-out of the sidewall and another towing by BMW roadside assistance. So much for Run Flat Tires allowing you to drive 50km to safety. All 4 ruined tires were essentially brand new, and were inflated to manufacturer's specifications. I am keenly aware that under-inflation of the tires will make pinch-flats more likely, and I am meticulous in maintaining proper inflation pressures at all times.

As soon as my current set is worn out - which won't take long because of the rapid tire wear, I am replacing my summer rims with 19", and increasing the sidewall width to fix this problem once and for all. My winter rims and tires are 245/50/R19 and they have performed flawlessly on our punishing Canadian winter roads.

Ten - 10!! Bridgestone Alenza tires for 24,000 miles of summer driving is crazy, and they're not cheap either!

I live in the Pacific Northwest (WA state) and haven't noticed any issue with hydroplaning, including heavy rain at a "spirited" rate of speed. I'm always shocked when I think it's imminent but nothing goes wrong. My tires have been pretty sticky in dry and don't cause me concern in rain/wet. I haven't gotten the tires to squeal, so that's probably why they don't seem to be wearing yet. Love the tires and the car!

I am happy with them and enjoying the smooth ride

Although these tires provide a decent ride and are fairly responsive, they are just too expensive to only get less than 16,000 miles wear. if you don't care to spend the money and keep replacing, the traction and responsiveness on the BMW X3 won't dissapoint.

I bought this tire as a replacement for a damaged tire that picked up a screw. It is the exact same tire that was damaged. The damaged tire performed in the run flat state exactly as intended as I had to drive about 8 miles with the tire being flat at speeds of up to 35 mph. For anybody purchasing run flat tires, this is a great looking tire that performs at or above average and well worth the lower price point from the higher name brands.

Love the tire hate the tread wear , I have gone through 3 sets of this tire maximum mileage you can get with these before you hit the tread wear indicators is 7800miles why can they make tire last a bit longer , they are very expensive and hard to find

I have had a terrible experience with the Bridgestone Alenza tires that came as OEM on my BMW X3 M40i with 21" rims and run-flat technology. The tread life of these tires is only around 6,500 miles and even a single puncture often requires replacement of both left and right tires for safety reasons. As a result, I have to eplace the tires almost every year. Additionally, the ride noise is quite loud, the grip when wet is bad and the ride is hard, which is what I would say is a common issue with the many run-flat tires I've had on other BMWs. I have decided to switch from Alenza tires to Michelin Primacy Tour tires. The Alenza tires are too expensive and suitable only for summer use, whereas the Primacy Tour, although not having run-flat technology, will hopefully last twice as long if not longer. If you like expensive tires that need to be replaced anually, these are the tires for you, look elsewhere such Michelin for better tires for your BMW.

Tire performance is ok but tread life is terrible. Came with my BMW and they lasted less than 15k miles.
