depends on what there on, i have seen fifteen year old riding mowers with original tires. my tire guy says they are trying to pass a law that won't allow them to sell a new tire that's been on the shelf for over six years, rule of thumb is a tire that's driven on should be replaced after 5 years reguardless of its tread or miliage, something about the oils in the rubber break down and they lose flexibility, and begin to dry rot, i check mine with every oil change looking for weather cracks or bubbles, that is when you know it's time for new ones
Most manufacturers have a five year limit on warranties, so I would say five years is a pretty good rule of thumb
No. UV damage won't occur if the tires are stored in long term storage. Most likely they won't be exposed to any UV damage since they will be stored indoors.
Depends. Whenever dry rotting occurs trash them. Unsafe to use possible blow out may occur.
Dry rot happens when the vehicle sits too much. If possible drive the vehicle even for shot distances, to rotate the tires. If the vehicle is being stored long term, then lifting the tires off of the ground will help slow the dry rot process.
It's never happened to me and I always store at least 4 tires for seasonal use.
How long your tires last depends on how you use them and where you drive with them however they should be able to last as long as comparable new tires.
There are several things one needs to consider when storing tires. One needs to make sure they are stored in a dry area. Putting trashbags around them to keep them dry and safe is also important. Finally, one should make sure to write down the previous position of the tires on those bags, as worn tires can behave differently when put on different wheels.
As long as all 4 tires are the same size, you will be ok.As long as all 4 tires are the same size, you will be ok.
Yes , you can, as long as same tires on one axle.
This really depends on how much you drive, what you're driving on, and if you get your tires rotated. Take a look at the warranty that comes with your tires to see how long you're covered for.
Salt and pepper can be stored indefinitely.
Some types of energy can be stored; some can't be stored for long.
In a sense yes. When tires are exposed to the ozone, or to sunlight they begin to break down and will dry rot. If tires are stored in an airtight bag indoors they can be safe to store for up to 5 years. Never buy a tire that is over 1 year old.
