Tires OEM BMW or RIKEN

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.

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

Speaking of cheap tires, I recently switched my tired old 41k mile Sumitomo ZIII with these $43 in 225/45 17 Riken raptor ZR and quite surprised how well they are. They grip as good as my ZIII did, way quieter and rain performance was fantastic. I was hesitant at first until I read reviews on tirerack phrasing these are great tires and they are definitely good. I also learned Riken is part of the Michelin tires company so its probably of decent build quality.

They have an aggressive tread pattern and I have driven them for the last 7 months in a variety of conditions from downpouring rain to hot, humid sun and they have not let me down yet. I push them hard on a cloverleaf on-ramps. They grip well and don't even chirp.

Have these on the 944 and they are surprisingly good. Not pirelli p7 good, but good and they hold up. Honestly I have no issues with them. (Riken Raptor ZR summers)

+1 used those on my e90 BMW last year during the 'record' snowfall and the were great.

My “RíKEN RAPTOR” tires sound pretty… well I think about my driving on cooler temp roads with corners or any moisture.

We used to use the P Zero Nero as they came on our mustang but they just didn't have the traction we wanted...We replaced them with RIKEN RIKEN RAPTOR ZR tires @ about $100 each (raw tire)

The Riken handle better on blacktop, although it's no super sticky tire but the front end doesn't plow near as bad.

It was a commonly traversed dirt road, a little soggy after a rain storm and I backed my dad\u2019s brand new 2008 335i into a small mud depression with the right rear only. Result? Absolutely dead immobile

The run flat tires are terrible. They feel like they are made of concrete and the grip is very lacking.
