No spare, 2012 e-Assist
it doesn't ruin the tire, only the TPMSBefore I purchased my Lacrosse I had downloaded a copy of the owners manual and it was then that I became aware of the no spare option. From what I understand is if you use the sealant to fill your flat to get you going again you've pretty much ruined the tire. While I might have saved a hundred bucks at time of purchase its going to cost me a lot more to replace it for the sake of a simple patch. Plus if you get a side wall puncture or cut you're hooped and stuck on the side of the road and where I live a flat in the country could mean a long wait for a tow truck. No thanks. I'd rather have the spare tire. When I buy my next car, and it has a sealant kit with no space for a spare it will be a make-or-break deal.
In our cars we carry pretty much the same except no bungees but instead a collapsable shovel for snow, a blanket and snow boots. All for the most dangerous season, winter.My 2010 CXL AWD has a spare. Beyond the sealant impact on the tire, what about the pressure sensors? I've carried my own little compressor and a plug kit for years in each vehicle. Good insurance that doesn't take up much space. I have these along with jumper cables, a tarp, rope, gloves, and a few bungees tucked around the spare tire.
