Discount Tire can't even get tire pressure right. They set mine to around 40 PSI last time I was there, when the invoice and door jamb clearly say 32 PSI. I have P-rated tires not LT, so 32 is correct. I usually keep them a bit higher, maybe 34-35, but not 42!
When I bought tires from them, they "made a mistake" recording the mileage, but I suspect they were hoping I didn't notice trying to short me on the warranty. The first digit was right and the rest weren't even close, so I don't think it was just a typo. Joke's on them because I just bought the 4runner before I got tires, so the mileage and date are clearly recorded on the title. Not that I'd ever be able to make a warranty claim anyway since tire warranties are not very useful.
