Well I bit the bullet and bought new wheels and tires for the rear. I posted a while back and thought I would show the outcome. I like the new look and it rides much better! Old: New:
I like the new look,but in old photo there is way too much PSI in big rears to ever ride OK,hope you did not try riding that way,should of had about 10lbs only in them,the new smaller tire should be good around 20 to 22.
I used between 10-12 pounds in the rear. I tried both to see which rode better. Not sure what I had in that picture.
