Generally wheels should stay true for quite a while if they are built right.
What type of riding do you do? Do you ride over curbs? Hard core mountain riding? Mostly on the road?
Which new wheel did you buy?
I have ridden my factory wheels on a Giant Sedona for 3,000+ miles, and I weigh over 300 pounds, but I ride only on the road, or rail trails.
