Lol. I was so sick of headlights reviews that were just garage door pictures without objective evidence that I just bought a light meter and was about to do this same test tonight.
I just replaced the stock tires. I have read every AT tire thread on the internet. There doesn't seem to be a clear winner. Maybe 2 years ago it was the Falkens when they were cheap, but they are priced the same as everything else these days.
I went with GoodYear Ultraterrains. Reports say...
I had KO2s on two vehicles. The first 15k miles or so were great. After that, wet traction got stupidly bad. For my needs, the Cooper AT3 has been great.
I had to trade in my 2004 V8 for a 2020 6. The V8 makes a lot of power down low in the RPM range. The 6 has to downshift anytime it thinks about going anywhere. I hate it.
