Hi, everyone. Im a newbie rider, and just putz around for fun on paths and stuff mostly. Just bought a new Diamondback Apex 29er mtb and its a great bike but i just wanna swap out my knobbies for some more road and path friendly treads. Im just having problems wrapping my mind around tire sizes. The mtb tires on it are 29x2.1. I understand that 700c and 29" are equivalent rims. Im wondering about tire width. 2.1 comes out to around 53mm but ive been told to get 35s. Wouldnt you want to aim for something closer to 53? 35 just sounds so small. Its confusing. Im 5'11" and about 240lbs so a bigger tire is better, right? I found some Continental tour ride tires in 700x47c. Can i use 42s or should i stick with 47s and bigger?
