Tires OEM BMW or OEM Porsche

Awesome bike, but swap out the stock tires asap.

Swapped my wifes Z4 from runflats to normal.

Pros: better ride, less likely to crack rims, cheaper tyres.

Cons: no spare tyre.

Before I switched I had 4 sidewall tears, one bent wheel, and one cracked wheel. $3000 in damage. After I switched, zero issues a year and a half later. Smoother ride and less road noise too.

Punctures that didn't go deep in the tread usually would be fine. Looks llike they sprayed water on it and there are no air bubbles indicating air leaking.

For better handling and winter traction, I would consider getting wider tires.

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.

OEM tires wear a little faster than I'd like. I'm looking at having to get some new ones soon.

Just be warned I bought new and we don’t drive it wild or anything but both rear tires (non staggered 21”) were at 3mm tread after 10k miles and I had to replace them. Was shocking.

I got the wheel and tire warranty when I bought my car. They’ve already replaced 4 run flats for free. I got 2 blowouts in the last 2 weeks hitting pretty average sized potholes that I’ve never had issues before with. Run flats suck.

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
