At the DT website is this statement:
"We do not recommend downgrading the speed rating of your tires. This may result in poor handling and unpredictable steering. However, if you want better cornering response, there is no problem installing a higher speed rated tire on your vehicle."
In your experience buying tires at a DT store, have they refused to sell you a set of tires one step lower in speed rating than your OE tires? Or have they just recommended you not go lower, and then sell you the tires anyway?
