New Michelins

I just replaced my OEM 215/40/18 front tires with 225/40/18 Michelin non-Run Flats, and the OEM 245/35/18 back tires with 245/40/18 Michelin non-Run Flats. This is on my 2009 135i with M Sport package, and the replacement tires are Michelin Pilot Sport All Season tires.

What a HUGE difference in ride quality and quietness. I got 25,000 miles out of the original run-flats, but would have swapped them out earlier if I had known what a big difference they would make.

Best of all, my local BMW dealer did the mounting/balancing swap for $120. Thanks to others on this forum who pointed me in this direction.

I have a 2009 135 Vert with the sport package...just got it in December, and the tread on the OEM run flats is still good...better than 50%, but I have no idea how many miles are on them. I'm debating on whether to keep them till they need to be replaced or go ahead and ditch them for some non-run flats. I know I'll be happier with the new tires, but it's hard to get rid of good tread. Decisions, decisions.

My question is what are you (or others) doing about flats or other potential emergencies? There's no room for a small spare in the trunk like a 3 series, and I've been told that sealant/compressor kits won't work if the seal on the rim is broken. They will work ok if a tire is low, but not a flat. I drive a lot in the mountains, where there are lots of pot holes and rocks, etc. and I'd hate to spend hours stranded waiting on a tow truck.

Do you have a backup plan, or just going to take your chances?

I change when tire tread depth is 4/32nds not 2/32nds like legally required.

A very informative video on tread depth.

I keep these two items in all my vehicles, even those that have a spare.

Quote from above site. "the temporarily sealed tire is ready to be driven for up to 125 miles (200 km) at speeds up to 50 mph"

I figure if one doesn't work the other might?

Ps. My son also has a 2009 135 Vert

You can certainly get a spare tire like this one
http://www.bimmerzone.com/BMW_Perfor...82E88-KIT.html

while there is not room under the trunk, most people put it above the carpet and strap it

Fix a flat is ok but of course if you get a big slash on your tire its not going to work. mainly works for small puncture leaks.

Unless you plan to track the car I would leave the runflats on...no use in throwing away good rubber.

And some of those who ditch the runflats carry a can of fix-a-flat, just in case.

Any time you switch out of RFT's you will get a very big improvement in ride quality. Took mine off the 335is @ 1500 miles & put them in my storage shed. They will be my last change when its time to sell the car. The 135is will get a tire swap right after break-in. I carry a flat fix package in the car + AAA if its a bad flat.

+1, RFT suck. I would never use them again. Last two cars I bought gave the new tires to the dealer and had them put on before leaving lot. Kept RFT in storage until I gave car back. Drive quality is night and day.

And you had no problem putting those tires on the existing wheels that previously had tires that were 10 mm thinner? I have always wondered if this was possible...this may help to dial out some of the perceived understeer that this car has. I am about to take delivery of a 2010 135i M sport and it likely needs new front tires soon. Thanks.

In reading about the inflation kits it seems some have warnings that the sealant will harm the TPMS and others say they are safe for them.

Anybody have their pressure monitors ruined by one of these kits?

My daughter has a 335D and needs tires soon. I am recommending she ditches the run-flats. She will likely get a spare tire/jack kit for the trunk, but with my 135 vert I don't have room for a spare. Looks like my only option is a sealant kit and AAA.

I just need to find one that won't add $200 to the mix for a new TPMS.

What about first trying the plug kit I mentioned in my first reply?

If you do need the sealant a set of 4 sensors and required valves are $192 at tire rack. They might sell them individually?
