I'm a newb. I've noticed some people rotate the spare tire. Is this the norm? Does everyone do this? I've never owned a vehicle with a full size spare. So I would have just rotated the 4 and never even touched the spare. I am afraid of it rotting as the FL sun is brutal but figured a tire cover would help. Am I totally wrong for thinking like this? Please advise. Thanks.

Most that have a matching spare rotate it in when rotating.

I feel like doing that will always leave 1 tire with just a little more tread then the other 3. It's probably just my OCD but I feel like that's not a good thing. Is it not that noticeable?

If you rotate them every 5,000 miles like it recommends in your owner's manual they will all wear evenly. If you wait until 15k miles there might be an uneven wear issue. Here's the proper pattern for rotating.

Rotate it in. Even if you decided you wanted another set of the oem tires. Longer overall tire life.

Rotating all 5 is a good thing. As for the sun all the tires will be exposed and if your doing any off roading you do not wont to put a tire cove on the 5th. It will hold dirt, mud, water and sand.

Tires are made of vulcanized rubber (no, Mr. Spock is not involved). Vulcanized rubber needs to be periodically reheated or it will loose its "rubbery" properties, or what some people call rot.

The nice thing about tires is that simply driving on them, reheats the rubber. So, including your spare tire in the rotation, ensures that it gets some road time.

I just did a 5 tire rotation this past weekend. Wanted to keep the wear even so if I ever needed that spare.

We haven't used vulcanized rubber for decades. All rubber is now synthetics, usually from petroleum compounds (though I have seen some made from extracts of Soybeans, those zany Chemical Engineers!)

Ultra Violet (UV) light exposure and age, however will break down the plasticizers and long chain molecules which form synthetic rubber. The same wavelengths of light that give you a sunburn are to blame, but don't fool yourself thinking sunscreen or wheel dressing will save your tires.

Tiny cracks you see around the exposed sides of tires are not usually a sign of wear, but hardening. While that's on the surface your internal plies don't suffer the UV damage and are still going to give you good service.

Generally, I expect the most reliable life of a tire is going to be in the first ten years you own it. After that you are taking chances. Delamination often happens with older tires, where plies and belts separate.

Saving your spare's virgin tread for that day you get a flat isn't the best use of a $200-300 tire. Rotate it in and replace the full set of 5 when the time comes.

Nope.

Vulcanization is a chemical process by which the physical properties of natural or synthetic rubber are improved.

Mark me down as another one who likes to rotate all 5 tires (like the diagram above), when performing the periodic maintenance.
All the tires wear even this way through their life.

I keep a tire cover on the spare when on road, but take it off for trail rides. Mostly so stuff can hang off the spare (trash bag, ramps, smiley face drawn in chalk, etc).

Ding ding ding. If you get a flat and your tires are half worn then you'll have a really uneven spare or need to buy another.

Another vote for 5 tire rotation for all the above reasons.

Another benefit to a 5 tire rotation if you do it your self at home you only need to jack 1 wheel at a time. the disadvantage if you are a old fart like me is lifting that last tire and wheel back on the spare tire carrier.

Absolutely not. Rotating all 5 tires every 3,000 miles or 5,000klm ensures that the spare is always the same size and condition as the rest of the set.

Even the guys at Discount Tire recommend that we rotate our 5th tire. Usually when I come in, they scramble to work on my JEEP - Mainly because they love JEEPs... One of the guys told me last month while getting the tires rotated that he was graduating from college soon and once he gets his first Big Boy Job, he's getting himself a JEEP.

5 tire rotation is a "no brainer" - you pay for the 5th tire, why leave 20% of your useable tire life sitting uselessly on the back of your Jeep? Rotate five tires, replace five tires - you always have similarly worn, good to go tires on your Jeep. Don't be the guy with a 37 inch tire and a 32 inch spare...which I saw today. =)

I always rotate my spare tire into the mix, once all your tires wear down I would choose the best one left and put it on your spare. Then go to 4 tire rotation only if you plan on keeping that same size tire. Unless you want to show off a brand new tire on your tire carrier!?.

I have had to replace three tires of the original five duratracs ( Discounts warranty is the bomb). anyway,,,I put the new tires into the rotation as if nothing had happened and after doing a rotation this past Sunday I cannot tell which ones are new and which ones are the originals. We have 20,000 miles on this set. Extremely even tire ware doing a five tire rotation. Highly recommend it at least every 5K miles.

Yeah, those DT guys love jeeps. Every time I go in, even the manager comes out and talks to me. They come out and see if I have any damage to my Jeep. They know that I go wheeling.

I just started the 5 tire rotation on my Jeep. Seemed like a no brainer to me. Seems like a waist not to get some use out of the full size spare. Plus 5 tire rotation is so much easier at home.

It's good practice, knowing how and what to expect when changing each wheel. Nobody wants that day of reckoning, when they flat on road or trail, but having experience with jacking, shifting the wheel weight, etc. is good for your karma.
