After 7200 miles on the runflat tires, my car is starting to sound like a monster truck. Sure, as long as I keep the L7 cranked up I don't hear it.

I'm trying to decided if I should bail out on these tires (and save them for the end-of-lease turn-in) of if I should bite the bullet and just wear them out (which shouldn't be too long).

Anyone else with runflats and some miles hearing an increase in tire noise?

I have approx 7500 miles and the Dunlop r/f are beginning to like a car with faulty wheel bearings!

And I am in the same predicament - to bail out or let them run out , but the noise is beginning to become unbearable .

It was one of my complain from the very beginning and now our dealer's General Manager is refusing to help. Co-incidentally I just had the disappointing words from him this morning .

I just burned through my first set at 20,000 miles and it got pretty noisy towards the end. The new set which just got mounted a few days ago isnt that much quieter, so like Rudy I just crank up the volume on my audio (which incidentally isnt too high - another thing see my dealer about).

I was thinking of getting a set of non run flats but dont know if the sports suspension ride would be compromised. Anyone with an opinion on this?

I'm having the same feelings.. I don't understand why these tires have to make soooo much noise. C'mon it's 2004 can't they make a good design anymore???

I am now looking in new rimms with tires or just new tires.. The safety thing is keeping me from changing them asap.

You will see a significant improvement in ride quality. You can also get Maximum Performance tires, which is a higher rated tire than the Ultra-High performance runflats.

The problem with the runflats is they are basically solid rubber. This compromises their ride and handling, and adds about 12 lbs of weight to each tire. Non-runflats will reduce your unsprung weight significantly, and will ride and handle better. I just don't understand why BMW specified these as OEM tires on the 545.

My car has Bridgestone runflats mounted and I have the same problem. Right now I put something like 12000km (+7000 miles) on them and I was starting to notice it as well, at first I thought I was getting paranoide but now, after reading this I am pretty sure that I am not.

Another issue is the traction when the road is wet, the slightest push on the gas pedal feels like the tires are losing their traction, maybe it is because they are so hard? I also notice this when it's dry and I drive on a road marker (white lines on the road).

Anyway I am thinking about getting rid of the entire car or not.

Johan, you're thinking of dumping the car because the tires suck?

Because the tires suck and the ashtray is full...

No, I think he had more problems with it than just the tires...
