My daughter bought this vehicle and later figured out it did not have a spare tire. I researched and see it has the 2LT trim package with 16 inch wheels. Actual tires on the car are 205/55R16. (5 Lug). Can anyone tell me what size donut spare tire/wheel I should be looking for? Someone locally has a T115/70R16 off a 2006 Cobalt available...will that work? Anyone have this year vehicle and 16 inch tires that could tell me what was provided with their car or otherwise can look it up? Would really appreciate the info. Thanks!

Yes as long as bolt pattern is right, but keep in mine the donut should always go on as a back wheel like the owners manual says.

What Coby said. Any donut spare will work as long as the lug pattern is correct. I personally keep a full sized spare in my trunk. Yes, it's obtrusive, but I'd feel much safer driving on that than a donut.

Thanks! I saw that in the manual about putting it on the back wheel but it says it is for the Sport Model due to the larger performance brakes than a "Base Model". The paperwork for this car says "Model: 1AL69-2008 Cobalt LT Sedan". I've been assuming that was a base model...what would make it a sport model? Thanks again.

Ooops...think I got it...the Sport Model has the 2.4 L engine and different brakes, which is why the spare does not fit on the front...correct?

You should still put the donut on the back if you have any distance to roll to protect your differential from overheating due to the different tire ratio. Plus it will be much safer at higher speeds if the donut is in the back.

"Sport" model most likely refers to those with the 2.4L engine like you mentioned, but could also possibly refer to the SS, 2.0L models as well. Still, if you need to use the donut, put it on the back.
