Hey guys. IN the market for some new bi cycle tires. Mine are starting to split around the edges. I am a newbie rider and only ride about 70 miles a week for right now. Should I just stick with the same tires that came on my bi cycle? Bought a used bike with maxxis tires. Not looking to spend a lot considering I won't make efficient use out of great tires. Went to the LBS and they wanted me to get new rims, even suggested a new bi cycle all together. Thanks for any advise.
