I had the unfortunate occasion to pick up a screw in my right rear tire while at the grocery store, and came out of the store to discover my tire was flat as a fritter. I remembered the tire repair kit in the frunk, and followed the directions. It worked very well, and I took the repaired tire to my local BMW dealership where fortunately, they had a "free installation" deal going on. $179.00 mounted and balanced. I asked the service advisor how to go about getting more of that green sealer "goo" that works with the tire pump system. He said he'd order it for me. Well, it came in, and the bill for just the canister of tire sealant goo was $186.00 + tax.
Jeebus! That's a lot to pay for fancy Fix A Flat. I wanted to make sure I keep a spare in the kit, especially when lease turn in time rolls around..
Has anyone tried to use commonly available aerosol tire repair sealant? Surely BMW's tire pressure monitoring equipment can't be that fussy that It can't work with more pedestrian products..
