I would actually prefer they were all the same.
But, just the fact that Continental classifies them as “drive” and “steer” tires has me questioning if anyone has run the HDR+ (Heavy Drive Regional) on the front axle, vs. the HSR (Heavy Steer Regional) I’m using today.
To me, the HDR+ tread doesn’t look any more aggressive than the Michelin XPS Traction tires (which is also an open-shoulder M+S tire) I was running on both axles of my F350. The XPS’s aren’t marketed as either drive or steer, though.
I’m leaning towards buying two more HDR+ tires for the front once I get a few more miles out of the HSR’s that are on it. Maybe in a year or so. They’ll be 6.5-7 years old by then anyway.
