Got it! Sounds like tire warmers are the best plan then.
I’ve actually ordered a set of old bridgestone YPB tires as the “first try” (cik prime 2020). I know old tires aren’t gonna be great but the set of 4 brand new fronts from 2020 was discounted to 40€ including shipping and it’s apparently 36A at ambient temp, so probably soft enough even without requiring super high temperatures. Stored in a warehouse in the factory plastic wrap, so maybe it’s usable still. It’ll allow me to start testing the new chassis setup one salary earlier at the very least, before I drop a couple hundred on new tires and maybe even a second set of rims. And hey… can’t be worse than lawnmower slicks, right?
