thank you everyone for your help. i just picked up a pair of 2005 armadillo nimbus. i will let you know how they work out for me. now... one last question. they are going on a 2004 trek 6700 with a non suspension fork. i am 260 pounds and my entire commute is on the road and some sidewalk. the tires are 35-100psi. i have a pump capable of going well over 100.. so should i bring it up to about 85.... or should i ride at the max 100 psi???? would one be better for my rims?
