What is the best tires to replace the original ones? I'm hoping its not too expensive type of tires. I like how this Trekking 6 speed manual is quiet but the tires do need to be replaced due to some wear on the sides of one of the tires. The tires i currently have is the Continental Contact and have 68,500 miles on this vehicle when I bought this in Phoenix Arizona and had two previous owners. The original tires still have tread life. Any suggestions? I will be changing the oil/filter at the Chrysler-Fiat Dealership this week and have them check the battery. The vehicle manual transmission runs smoothly and encounter no problems so far. I like how the shifting of gears is so smooth and quiet. Is there anything else I need to check with this vehicle? How often do I need to update the U-connect system on my vehicle?
