The problem with modern cars is that they don’t come with spare tires. My BMW M2 certainly does not have one. In its trunk space where a spare is suppose to be, there’s the 12-volt battery (because race car), and a can of tire goo. There’s no emergency jack, or a lug wrench to take off the wheels. In the event of a puncture, I would hook that can to the faulty tire’s valve stem, and the goo is suppose to fill up the tire’s innards. Doing so is suppose to buy me just enough time and mileage to get the car to a tire repair shop.
Oh by the way, the punctured tire that I just filled with goo? It’s irreplaceable. Even if the offending hole is otherwise small enough to be patched. I guess BMW really expect its owners to have the income to replace a $300 tire (if you don’t cheap out, that is) without it hurting. Don’t forget: for balance, you typically should replace the other tire on the same axle as well. That’s $600 in potential repair simply because of a tiny piece of sharp object on the road surface. It’s either that, or call a tow truck. (Presumably, being left stranded on the side of the road is not a choosable option.)
I went with a third option: making and packing my own emergency tire kit. The consensus on the best scissor jack for BMW cars is this $25 unit from Harbor Freight. The head fits into BMW jacking points perfectly. Also from Harbor Freight is this heavy duty tire repair kit. It has everything: plier to extract the foreign object, reamer to prepare the hole, insertion tool for the rubber plugs, and a blade to cut off the excess. The $22 it costs is vastly cheaper than replacing an entire tire. You hate on Made in China until you have to pay for Made in the USA prices.
Lastly, I bought this lug wrench from Amazon. It’s got the necessary 17mm socket for BMW lug bolts. With these three tools packed in the M2’s trunk, I can tackle any puncture during road trips, short of something catastrophic. (That can of goo isn’t going to do much for a hole that size, either.) Best of all, I can take these tools with me to whatever my next car would be. Because it’s very likely that will also not have a spare tire or emergency tools.
Power of the sun.
