spare tire question

[mprobst]

I have not had a spare since I bought my truck. finally went to the used parts place and picked one up. noticed it does not have the beveled (?) holes for the lug nuts to fit into? it looks like some type of lock washer or big nut was used instead. it does not look like a dually wheel, so I don't think that is the issue. I will try to post a pic later today. do I need to return it (if i even can) and keep looking for the right one? also if I have 285/85r16 tires, would it hurt for the spare to be 235/85r16? how close in size do they need to be?

I hope you are not running 185s those are super skinny and wayyyy to short. It would make your speedo way off.

285's, not 185. I edited my original post, thanks for catching that.

The factory rims don't use the tapered lug nuts... there is an attached washer. The rims are 'hub'-centric... not 'lug'-centric, so the wheel is centered on the hub, by the hub, not the lug nuts with a cone shape.

As to the tires size difference, it would work, but dont' recomend it, due to odd handling issues. If you HAVE to run and odd size spare, do so with caution, and for as short a time as possible.

Also if you used the odd size tire as a spare I would recommend that you use it on the front with your hubs unlocked especially if you have a limitedslip differential. If you get a flat on the rear just put the spare on the front and move the front to the back. Then take it easy because it will probably gable alittle squirrely, but should get you to a tire shop.

Do this ^^^. And as mentioned before, the stock lug nuts have a washer looking thing on the end, they're not acorn style. The shop gave you the correct spare tire.
