I got my bike plated and need to change out my knobs for some more street friendly tires. I will mostly be riding to work just a few miles away with a mix of dirt roads and asphalt. I cant afford much but do not want to buy junk either. Something that wont scare the hell out of me at 55mph on the road. What do you all run on your plated bikes? I know I shouldnt be cheap here but I really dont have much choice. Any sugesstions for the most bang for the buck?
