Tires FEDERAL or OEM Porsche

I just went from Federal 595 RS-RR (very loud but performed well on street and autocross) to their 595 RS-Pro (waaaaay quiter, I love these tires so far).

I also own a set of these, I can confirm. Fits my BMW very well as they used to make airplane engines, and these sound like a Messerschmidt prop plane.

Wear earplugs. They're great.

Skip the brake fluid flush. Go find tires elsewhere. I have a Macan and got non N rated all season tires. Way cheaper than what Porsche will sell you.

I have Federal Himalaya Inverno K1 on my Highlander and they are boss. Never gotten stuck. Never had traction issues and I can go 120 in a blizzard

Federals will be really noisy after a few thousand miles. Almost like your wheel bearings don’t exist anymore. Had rs-rr and 615k+. 615k+ is better. Both are way off pace but great budget tires. 615k+ is actually a pretty good tire for hpde.

The next set of Federal 595 RS-Pro lasted 30k and looked like OP tires.

Chinese snow tires are hit or miss. I had a set of federals for a short while that handled snow great for what they were.

I own a 991.2 GT3 and its a terrible daily. No lane keep or radar cruise. No parking sensors. No keyless entry. Fixed carbon buckets. No heated steering wheel. Loud tire noise. etc.

In size 225/40 (r18), their thread width is comparable to other makers ~205. Well, does it matter? Yes, in the sense that when you install them onto an 8.5 wide rim, you'll notice that you're stretching the fit, and the sweating starts. Installing a tire alone with a basic tire machine is no longer possible.
