Tires OEM BMW or Goodyear

HD thrust arms are an improvement without too much sacrifice. Better shocks as well. I’ve found tires make a huge difference with the E39.

If you want less road noise and smoother ride get some Goodyear assurance comfort drive

Narrow, low-profile tires aren't as forgiving over potholes, especially when riding on the 20" wheels.

We have Goodyear WeatherReady Assurance tires on our Acura MDX and they are far and away the best all-season tires I've ever had. They go nearly toe-to-toe with summer tires and also perform exceptionally in the wet, on ice, and with snow.

I got 4 new Goodyear assurance on my civic for about 450 on some sale, through goodyear's website. The techs fucked up my tpms, but the tires are noticeably better than the old ones.

Got winters and they make a huge difference.

knew I should have replaced them before we left - New Goodyear Endurance all the way around

Good tires, good in wintery conditions, but noisy and pricey.

I’ve gotten 3 flats with those tires, they aren’t the best

I just put new Goodyears on my trailer. One of the 4 was a GY Marathon and it feels so squishy and the sidewalls just feel weak compared to the other Chinese tires so its going in the trash for sure.
