Hello all, I have read almost all of the post on here in regards to the spare tire issue. Having a spare tire is important to me. I may never use it, I also have AAA, but you never know when the time comes and you wish you had a spare.
I ordered the jack from GM- part #23455285, I bought a 19mm ratcheting wrench, bought a gorilla breaker bar, that comes with the necessary accessories to remove the lug nuts. Now here is where things got tricky. I read that the spare from a DTS 2005 gen will work. I bought one for $50 and it came with a brand new, never used conti tire. 125/70/17. I installed the rim on the front, dropped the car down, and it rubbed on the caliper. So this did not work. Im sure it fits the back just fine, but not the front. So I bought a spare from a 2018 Equinox, same as a 2018 Impala part #560-08121 or cross reference 84095141, tire size 125/70/17. Just got it today, paid $80 shipped. It worked perfect. Drove the car up and down the street, no issues. The tire is much thinner and obviously lower than stock, so the car does lean. But its a spare, so im figuring 20-25 miles driving to get to a safer or better area, or off the highway its perfect. I had more than enough room to put the jack and the other tools in the spare tire wheel well. And the sub fits perfectly just like factory.
I hope this helps someone out.
