any new tire is going to be an improvement over an old dry cracked tire. if its working for you then its a good tire. a lot of people dont trust CS tires, but from what i can tell there are not a lot of first hand reasons for the mistrust. They are cheap and chinese. check them for dry rot and weathering on a regular basis. replace when the rubber gets hard even if its before the tread goes and you will be fine.
keep the maxxi side down
