I had a 2016 TM01, I couldn’t run a 25 up front because of the rake. On the rear a 25 was fine but my limit screws were pushed out at almost max. I didn’t run 858s. I went with a 23/25 combo
This was my experience too. Hed Jet Plus with Conti 4000 sii. The Zipp wheels and a less oversized tire might sneak a 25 up front.
