Wrong size spare tire on Avalanche.

While driving at normal city speed emergency spare tire fell off on the street. Tire bounced twice and hit another vehicle. Dealer stated this was unusual, never heard such thing.

Spare tire in the vehicle is a different size then the one on vehicle. Tire on vehicle is 17 inches and spare tire is 16 inches. Contacted dealer who is not willing to do anything. Consumer adds owners manual states that mixing tires could cause loss of control while driving. Manufacturer is aware.

Four primary tires are 17" inches. However, emergency spare tire is 16" inches. A mechanic informed consumer it would be unsafe for him to operate vehicle using 16" spare tire in combination with a 17" spare tire on same axle. Please provide any additional information / attachments.

Vehicle has four goodyear 17 inch tires, and for the spare tire there is a firestone 16 inch. Consumer is concerned. Consumer states that gm will not solve the problem.

I have not experienced a tire failure yet, but I have concerns on the spare tire that came with my vehicle. The 4 main tires are goodyear wrangler hp 265/70r17 and the spare tire is a firestone wilderness at p265/75r16. The owner's manual specifically states to use same size tires & type of tires. The spare tire should be the same as the premium tire package I upgraded my package to. . . Not a smaller size without any warning of what damage it could do to the vehicle if you used it for an extended period. . . . I think they should have the same size spare. If not, at least inform you of the potential damage one could do to their vehicle or person. (tiresize: p265/75r16).

I do not understand why the full size spare is firestone 265/75r16 vs the four goodyear tires size 265/70r17. Using different size tires is not recommend in the owners manual so why would they give you a spare that is different from the other tires & do not mention any hazards.

Truck came through with 17"wheels and 17" goodyear tires, the spare tire is a 16" wheel and 16" firestone tire. My truck is a 4 wheel drive, if I would have to use this spare, I feel it would be unsafe putting different size wheel and tire on my vehicle,. I have a complaint into the Chevrolet customer service, but they said that they won't do anything about it, that this is the way this vehicle comes through, I was never told this by the dealership, I also complained to them, and they haven't done anything yet. My complaint no. With Chevrolet is (05525998), the person I spoke to was named christine. The telephone no I called was 1-800-222-1020.

While driving 40 mph consumer heard a loud noise coming from the rear. Consumer was able to maintain control of the vehicle, and pulled over. Consumer inspected the vehicle, and noticed that the spare tire was not in place. Vehicle was taken to the dealer for inspection, and mechanic determined that the cable assembly needed to be replaced.
