M340i - Replace my run flats with non-run flats?

Hi everyone, my m340 I came with Cinturato run flat tires. I’ve noticed that the two front tires have multiple air bubbles on the side walls!!! So I’m thinking I should replace them asap.

In your experience, do you think it’s best to replace all of them with non-runflat tires instead? Are those any better? Which brand/model would you recommend?

Thanks in advance!

Literally happened to me as well smh, thinking about swapping out to non run flats since I'm going stage 2. Will have to eventually purchase tires within the 3 year lease

Definitely change them. Run flats makes the ride uneasy on bumps and I have changed mine to non run flats and I like them. Only downside is not having a spare tire but I have a pump in my car just in case and if I do run into a flat tire, I may need to keep pumping the tire till I reach a tire shop.

I ordered the car with non-flats + a spare and couldn't have been happier. Definitively get rid of the runflats.

Just on this - I've had my M340i X in for some work this AM and they did a complimentary health check - check tyres, suspension, brakes etc.

It currently has runcraps on from new. Front tyres 5mm. The rears: 3mm. So lost 50% of tread. I've done 4200 miles. No track days, normal road driving.

My MPSS4S on my previous M140i which was rear drive only lasted 12000 and I did like a spirited drive in that.

Madness although a food excuse to get rid of the runcraps soon!

It depends if you want summer, all season, or winter tires. For all season, I went with Michelin Pilot Sport A/S 3 +. Very good tires.

Late to the party here and new to the forum… I have run flats on the car and it was the only option. But I spec’d the spare tire with the intent of getting non-run flats. My only concern is bent rims. Has anyone had an issue with this? The autobahn is great but the secondary roads in Germany are terrible. Also, any recommendations on tires? I plan on swapping winter rims to summer tires and I’ve always gone for Michelin but I’m considering Vredestein.

I just replaced my OEM cinturato with a non-run-flat set of Continental DWS06 in slightly larger size (235/40/19) and am very impressed.

The car runs more smoothly over rough pavement and grips better, too.

I'm running Vredestein winters on my '16 GTI and am really impressed with them. Came from a set of Michelin Alpin's prior and while I liked the Michelins, the Vredestein price point and performance are a much better value.

I've got non-runflats on my '23 M340 and am going to be swapping them for Conti DWS06+s later this year.

For those that ditched run-flats and don't have a spare, are you relying on roadside service, or did you get a plug set/jack/air pump (or find an aftermarket spare)?

I always keep a tire plug kit and a portable tire inflator off Amazon in case of emergency in the trunk.

I got my tires through Tire Rack, which came with 2 years of roadside assistance for free.
