Many threads out there, but usually comparing worn OEM tires to brand new tires. This will be comparing brand new to brand new, some subjective results and some data.
Configuration: Gen 1 R1T Dual, 21" wheels, Aero covers removed
Location: PNW, mostly Seattle region mix of commute local highway, etc
Backstory:
My OEM tires were a bit worn, and due for replacement. Heard good things about the Michilen Defenders, did all the research and had them installed at the local discount tire. Next day I had a full alignment at the local service center, all was well. I drove those for ~1500 miles before I finally replaced them with the OEM Pirellis (also at discount tire) because I couldn't take the road noise any longer (more on that later). I've since driven the Pirellis a full 1500 miles as well and can say I have a solid back to back comparison. The weather, season, and roads were nearly identical during the time.
Subjective Results:
The Pirellis are quieter. I mean, what is strange is that the Michelin was actually much quieter at low speeds around town, at least from the outside (windows down). The problem was highway speeds. Above about 55-60 there was a... hum. Not super loud... but incredibly annoying, at least to me. It was steady, happened on multiple roads, almost like a harmonic. This doesn't seem to occur much to other sizes from what I've heard from other owners, so it might be something with this size ratio? Either way, I couldn't take it any longer so I took them back. We tried rebalancing, pressure, etc; no change. So I decided it was time to experiment by going back to the OEM tire and compare it.
Ride wise I felt they were pretty similar. Michelin was a tad softer, but they both handled fine.
Efficiency Data:
Since this was an experiment I was very careful to keep things as similar as possible. I left it in standard mode nearly all the time. Towed a trailer maybe 20 miles with each set, and generally drove the same pattern/location/routes. At ~1500 miles on the odometer they came in at:
Interestingly the Michelin's started out pretty much at 2.3 and didn't change much. The Pirelli's started out about the same, but slowly improved after the first 500 miles or so, leveling off at a reliable 2.5 by the 1000 mile mark.
Anyway, just another datapoint for the folks rocking the 21's out there.
