For safety and comfort reasons I trade OEM tires for better performing after market models within two weeks of obtaining a new vehicle. Some friends and family think I am wasting money and hurting the environment by "throwing away" perfectly good factory tires. I do not see that way at all.
I tend to lease cars for three years. My experience with OEM tires has been very negative: loud, harsh riding, poor dry and wet performance. It seems that many factory tires are designed to simply roll the car off the assembly line, and onto the cargo truck.
I do not want poor performing tires to ruin my three year driving experience, or to fail me in an emergency braking or steering situation. Also, I want to enjoy the driving dynamics the vehicle was engineered to provide. I want three years of quiet, safe and comfy driving. I may end up loosing a couple of mpg's because my car sticks to the road better, but I am willing to give up a little economy for years of peace of mind and enjoyment.
The oem tires I trade-in are not thrown away, they are not taken to a landfill; but rather offered to another consumer at a huge discount. Their getting tires with only a couple hundred miles on them, for a fraction of the cost of a brand new tire. I get tires I want, and they get what they are in the market for. Seems win-win to me.
So, when I am told that i am wasting money, and hurting the environment, I don't agree. I feel like I would be wasting money driving on ill-performing tires that don't let me fully enjoy a car that cost tens of thousands of dollars. What do you think about this.
I wouldn't have offered my opinion except that you DID ask...
It's still wasteful, not just from the inefficiency of the redistribution model of getting rid of them and new buyer finding them, but also wasteful to keep funding the new vehicle lease model instead of keeping a vehicle longer.
Now onto the finer points:
- OEM tires are usually not loud, nor harsh riding, on the contrary they are optimized for a smooth, low rolling resistance ride that achieves good fuel economy, at the expense of performance. I can only imagine that any notions otherwise are only based on vehicles where the OEM tires aged to a hardened compound state, and then, comparing to brand new aftermarket tires, of course the new tires haven't hardened yet.
- I don't see any reason the OEM tires would ruin a driving experience, unless this was a track car instead of use on public roads. Plenty of people manage to avoid getting in accidents with old OEM tires, so you should have no problem doing this with new OEM tires, unless the tires aren't the problem.
- The driving dynamics the vehicle was engineered to provide, were done so for the tires it came with. That is every bit part of the test drive experience before purchase or lease. They are not just to make it roll to move it as suggested.
- With the above stated, it's your money and if new tires make you happy, that's why they exist instead of only one shoe fits all tire designs, and it's good that you find a home for the prior tires, and good to help out someone needy enough to make the effort to look for gray market tires instead of purchasing through normal distribution channels, except that if you truly feel they are dangerous and soul-sucking

then you're enticing someone else to have this experience with them too? Still beats old worn out tires though, just suggesting that you can't really have it both ways, that they're so bad that.... someone else should drive on them.
