I just got a new set of kuhmo tires. 37/14/20... was wondering what a good psi to run in them for my truck. thank's brad
sugar works well too I've found.i dont think i have heard of the chalk test? ill double check, but i think there at 40 right now. i just dont want to spend that much money on them and they wear fast and funny and not get full potential out of them.
chalk test- make a line on road and drive acrossed or something and see if it picks up the chalk or what. thats just my guess for that. ha. i might be far off. or put chalk on tire and see if it imprints on road?
