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.
