As for handling, I challenge anyone to see if they can reliably tell the difference in a blind test on a regular road (not the track). Maybe the princess from the princess and the pea could.

Gotta pull it out and see if I can get reimbursed.

I'm pretty sure I can feel the difference between my 135is run flats and my winter run flats, and my summer tires. I wouldn't bet big money on it.

I'm going to keep the non run flats but when they wear out, as they surely quickly will, I suspect I'll go for a run flat next time, maybe even a high performance all weather, as it gets wet here more often than one might like. Will continue with real winter tires/wheels as well.

Or maybe the engineers in M division, since they still spec non-runflats on all M cars ?.....
Absolutely. There was a distinct and improved difference when I dumped the Pirelli run flats that were OEM and I went with Michelin Pilot Sport A/S 3+. I tend to drive with some spirit when conditions allow, and I've always sided with conventional A/S or performance tires over the hard and unresponsive run flats. A daily driver to some won't make a difference, but to those of us with experience and skill, it makes a world of difference, especially when you're pushing the limits of the car. I saw drastic improvements in wet conditions alone when I mad the swap.

Better than all RunFlats put together and will serve its purpose for daily drivers in all weather conditions. Having experience with both of these and its predecessor as well as those AWFUL RFT.

In the rain, yes. Dry traction, down on grip, but most wouldn't see the difference. I pushed hard on AS3's on my old GTI before getting PSS's to replace them. The PSS's had noticeably higher dry grip at the limits than the AS3's, but definitely down on wet grip, which is more important for most DD owners I'd imagine.. I always recommend the AS3's to the locals who want the best bang for buck performance tire, they've always come back raving!

Yes better is a relative term I should have appropriately qualified but yes to your point they're much better for a DD tire w roads by me at various times of year. Anything higher performance would be like paying for 8" of pussy when you've got 4" of dick.

That they do. I've tried to grow accustomed to it, but some days that's all I hear unless I crank the stereo. That's my only complaint about these tires. Dry, wet, and snow traction are every bit as good as claimed. I guess not all great things come without at least some detraction.

Very newbie here: I have a question re: 228i (normal) front tires beginning to show uneven wear on outsides. Rotate? Or not. (Non-Run Flat tires)

Also: What torque used for tire bolts?

Thanks

Aggressive cornering will wear the front tyre outer tread more than the rest, if it isn't too bad and the back tyres are the same size, rotation (front to back swap on the same side) will help to even out the wear, although there is a possibility of increased tyre noise due to the wear pattern after rotation.

Bolt torque is 140 Nm (103 lbft).

Be sure to drive at high speed if you change

I got regular tires on my 135 instead of run flats. They were totally fine until I drove 70 mph. Then my car wobbled side to side as if I was behind a tractor trailer. The tire dealer replaced them for free w run flats. I’m sorry, I can’t remember the make of the tires. But if you switch, I definitely recommend getting out on the highway sooner rather than later in case you have the same issue.

Was the car following the grooves in the road? It's called tramlining. I had none with RFTs. I switched to MPSS and have found that there is moderate tramlining on our grooved Tollway's. It's very unpopular with my passengers. Annoying for the driver. Disappointing and aggravating for the owner, which is me.

Nope, it wasn’t. I had to drive all the way from Georgia to South Carolina with it doing the back and forth. Had a death grip on the wheel. It could’ve been just that particular tire but we heard afterwards that it was a problem with using standard tires on a car designed for run flat. Thought I should mention it...some people might not get on the interstate for months when it’s too late.

Already posted how BMW highly frowns on replacing RFTs with non-OEMs. But tons of people have probably done this. Yes, could have been tire, or specific to 135, or both.

What are you running in your m240i?

Standard tyres are a factory option on the same cars that have run flats on too, there are no other changes other than the tyres. Low profile wide tyres with a flatter tread and stiffer sidewall are more likely to tramline compared with whether the tyre is run flat or not, a high performance summer tyre will likely tramline more than an all-season.

A death grip on the wheel and incorrect tyre pressure will cause the car to move around more, as you are constantly correcting out of phase with the tyre movement. A relaxed grip allowing the tyres to move a little without over correction tends to let the car track straighter, you just tend to feel the steering weight continually changing and telegraphing the road irregularities, as opposed to continually over correcting to the feedback.

I didn’t mean to start a conversation about which tires are best or how best to drive. All I know is I wished I’d done a trial run at high speed before I set off on a lengthy trip, so I thought a “heads up” might be appreciated. I never had trouble once I had run flats back on the car and the tire dealer agreed it was a problem with the tires, not inflation or driver error. I don’t know what I have on 240 - whatever came from the dealer 😃 Obviously I don’t know all that much about cars, or tires, just that I like to drive fun cars.

When you stated "we heard afterwards that it was a problem with using standard tires on a car designed for run flat", the person who made that statement didn't know what they were talking about. BMW sells the same cars with run-flat and non run-flat tyres on the same wheels sizes with the same tyre sizes and without any other suspension changes. The E82 135i when it was sold outside North America and the 2-series around the world and many other BMWs have both tyre options (SUVs being more limited in this respect).

A bad tyre could cause pull that you may have experienced, but it wouldn't be due to run-flat vs non run-flat. Tramlining as a characteristic can happen with any wide low profile tyre, irrespective of it's design. I expect the tyre dealer was happy to sell a set of tyres as opposed to getting to the root of the problem.

It is just false information that the current cars are designed or engineered specifically for run flats.

I'm glad you don't have the problem now, but if you want the best performance out of any sports car in the future, run flats and/or all-season tyres will be inferior to pure non run-flat summer tyres for non-winter use.
