question is. What is the condition/requirement to get the tire. If Lexus use the same condition that Toyota use. You might end up spend more than the actual tire cost.
Not sure about Lexus, because when they offer it to me. I turned it down right away, because it linked to the Toyota experience I had in the past. When I purchased my Toyota, they offered the same kind of program, Tire for life. I asked what I need to do in order to get the tire, and of course they always tell you is no catch. So I asked him to put everything in black and white, sign it, and put the Toyota dealer stamp on it. As soon as I asked that, his tone change 180. And finally honestly told me that, well, you will just need to get the regular service done. Regular?? What regular? just oil change for every 3K, or all the "extra" no needed services that Toyota "recommended"? Long story short, basically he told me, I will need to get the service done with Toyota plus something like I need to let them rotate tire, balance them once a while(I forgot the exact mile he told me, something like 7500 or every 10k), alignment all kind of good stuff that cost a ton, and pretty much don't really need it.
My conclusion is all the services that I pay for is surely will cover my tire cost.
I hope Lexus will give you a better/more honest deal.
