anyone know the difference in weight , heigth between 38.5 x 12.50 x 15 and 38.5 x 14.50 x 15 sx's i thought i read that the 12.50 is not as tall but i cant find where i read it here ...

ther's an almost 2in difference, and the weight i'm not sure, try interco's website...

Lance had a post several weeks ago that the 38.5x14.50's weigh 85 lbs. each. As far as height, I can't speak for the 12.50's but the 14.50's are 36.5" tall at street pressure (10lbs.)
