two niner question

I’m looking at building a 29er what do you think the best tire size is for commuting on the street, What size would be good for dirt?

Did you see the post a few below yours kh 29 v coker deluxe
or am I missunderstanding your question?

I’m asking size of the 29er tire ie 700x38c or like 29x 1.75

Schwalbe Big Apple 700c x 60mm. It’s the fattest road tyre out there and it’s what you want for road riding. Put lots of pressure in it and you’ll get a fantastic ride.

Narrower tyres are kind of fun to play with, but if you’re commuting, the big apple will be faster.
