Tires OEM BMW or SUNNY

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.

For what it's worth, I used to run the cheapest 235/40ZR18 tires I could find on my Jetta(Sunny brand if I recall), after a few years, I never had any complaints. Paid about $105 each and they seemed worth the money to me and not much different than the name brands($200+ each), at least as far as durability/safety was concerned

I have "SUNNY" tires on the Cavalier for summer. A-Ok so far for two seasons.

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

i had some sunny tires last year just bc i was looking for cheap tires they wore like **** i needed new tire in 15k. the fronts where showing belts and the rears where cupped badly so this year im getting some 512s
