My 07 came with run flats, no spare. Do others switch over to other HP non run flat tires and if so do you carry a spare?

[GATORB8]

Many switch and report significant gains in ride and handling. Hit or miss on adding a spare, slime kit, or rely on roadside.

There are many threads on this try a little searching.
Also there are many useful sub forums here.

I changed from stock 16' rims on run flats to 18' rims with conti tires and ride improved! This just says a lot about run flat and how it destroys the ride man. Downside is yes, you need to have either a small spare, a tire stitch can or rely on AAA/CAA etc.

I got rid of the run flats and got some Bridgestone REs and expected it to be amazing.

It's honestly overrated. My ride is still bumpy. Potholes are still grenades. The car was fast then and fast now so idk.

Most people either get a spare tire or sign up with AAA like me.

Switched from run flats to Michelin Pilot Sport A/S3's. Car handles so much better especially with the M3 suspension kit installed. For backup, I have a plug kit as well as a VIAIR portable air compressor in addition to CAA in case things get out of hand.

RE11? Those are some of the hardest sidewalks non runflat tires around. So, I can see why it wasn't a big difference in that case. Very grippy tho!

^ This.

It is a PIA to carry a spare in the trunk and pointless as well. Being that most cars after 2006 have some sort of tire pressure warning - it was a DOT mandate for MY 2008 and up (All E9X's do) there is really no need to carry a spare IMO. Keeping the equipment noted above in the well of the trunk is all that is needed to keep mobile in case of a tire issue. I've run nearly 295,000 miles on non-runflat tires since 2007 and have had to use the inflation kit twice to up the pressure on a tire that was compromised. The TPMS gives plenty of warning of a low pressure situation, which can be rectified in an emergency with an on-board (carried) air compressor, or gas station air pump. I'm sure CrippledL also keeps a tire air pressure gauge as part of his kit as well and just forgot to list it.

If there is a catastrophic issue with a tire say from pothole damage, your calling a tow truck anyway since there is likely rim damage/suspension damage as well.

My 2 cents

[patents]

I put on a set of Bridgestone Driveguards. Seem fine to me. I'm not a racer, and I'm not picky about the ride.

If you stay on OEM size wheels, I don't think you need a spare. As others have said, anything short of a catastrophic blowout is fixable with a plug kit + compressor or slime. If you run low profile tires in a less common size, a spare may help but you still may not need to keep it in the trunk.

I have 20"s and last year blew out a sidewall on the highway. That involved a tow home since I could actually put my hand threw the blowout, obviously not fixable. No local shops had the right tire in stock so it had to be ordered. Took a couple of days. Didn't bother me since it's not my primary car, but if it's your only car, keep that in mind. Again, not a concern if you run OEM sizes since those will probably be stocked everywhere.

I got rid of mine once they went bad. The way I look at it, you're paying way more money for what? If the tire gets a hole you can patch it sometimes, but if not you have to replace it anyway. IMO the run flats are a waste of money. Also I don't carry a spare because I like to live dangerously. Plus our cars are heavy enough as it is!

[Frost17]

Switched from RFTs to A/S3's. World of difference, handles so much better. Feels like a new car.

[jt335i]

Ditched the OEM RFTs as soon as it was time and switched to non-RFT Michelin PSSs and now on my second set of PSSs. Made a difference in ride and handling over the RFTs. After I made the switch, I bought a used compact spare and jack via LKQ auto salvage and the lug wrench at my local BMW. Cost me $163 overall. Didn't need a complete kit that online retailers charge $300+.

RE760s or something. That's interesting man. I noticed it to be very stiff but grippy. Maybe next time I'll get something else.

[tunachris]

I ditched the RFT as soon as they wore out. Carry a space saver spare, plug kit, and an air compressor. Went to Michelin PSS non-runflats, biggest mistake I ever made. Now I am spoiled rotten, and no other tire will do. Trouble is, I go through rears in about 15,000 miles and fronts in about 25,000 miles. Can't rotate them, so if and when I get rims, i am going to match the front/rear size.

[Bubba11]

I ditched the run flats years ago due to the harsh ride. I always carry a spare in my trunk since nobody seems to have my size in stock. I blew a month old winter tire today so it helps that I can swap it on now rather than wait 3 days for them to get on in the shop.

[Ponedude]

I was told by the tire shop that RFT's can only be repaired if the puncture goes exactly straight into tire, if there's any angle to the puncture, tire is done for. Shopping tires right now, i have a 07 328i sedan sports package, 2 different sizes on front and rear. I was told the bigger rear tire size has been discontinued and no ones making that size anymore let alone finding in stock. Im in colorado and they had to get them in from California. Anyone else run into this?

[ttthai]

I removed my run flats as soon as I could. I run Continental ExtremeContact DW in the summer and Bridgestone Blizzaks in the winter. I keep a patch kit, a bottle of slime and the BMW mobility repair kit in my trunk. No spare for me!

[tcphoto]

The original owner of my car replaced the run flats with Michelin Pilot Sports, I'll probably buy a spare and throw it in the trunk.

When I bought my car new in 07 I thought it was a little harsh but now I still have run flats and it doesn't bother me anymore

Run flats are over priced garbage that you get 1/2 the tread life out of and pay 33% more for.
