Tires Pirelli or Firestone

Up to you, but I wouldn't go high end on a C1. I wouldn't cheap out but go midrange. Something like Firestone MultiHawk 2s.

I've also replaced the worn original tires with Pirellis that I keep fully inflated, much smoother quieter ride than It got with the original tires and maybe getting a little better with the new tires.

I have personally used the Pirelli Cinturato P7s on 3 cars and they are very good tires, and lasted at least 40k miles before I sold the vehicle. And if it does happen to snow, you'll be covered, too

I like my Firestone destination at2 tires

I recently got the Firestone destination xt’s and they’re great. I only had Goodyear duratracs to compare to, but it was a vast improvement.

I had great luck with Pirelli Scorpion All Terrain Plus tires. Got a lot of miles out of them and when they wore done, they didn't get loud. Highly recommend these tires

Pirelli Scorpion AT+ on my 3rd Gen for 2 years and I love them. Noticeably more civilized on pavement and still excellent off road and in snow.

I've had quiet winter tires, to winter tires that roared (Firestone Winterforce)

Cant speak to the Falkens but Indy500s get greasy after a few good heat cycles

Hated these Firestone’s on my e30. Got very noisy when older, grip was inferior to a even a 10mm smaller width fallen rt615.
