I have a Sun x3-sx trike. I just put on new tires and tubes. On the rear are Odyssey 120psi 20" x 1.85 and on the front is a Kenda Kwest 100psi 16x1.50. I could tell a big difference in performance over the 65psi Kenda Kwest tires they replaced!

One of the rear tubes it was defective and blew destroying the rim. I only ran the new tires 2 days and on the 3rd one of them blew. The LBS strongly suggested putting in Sunlite thorn resistant 20x1.50-1.95 tubes on the rears, so I did. Unbelievable, but they are about as heavy as the tires!

To me they feel like I've lost the performance gain I got from going to the higher psi tires...in fact, they feel more sluggish than the 65psi tires. Is it me, or are they really holding back the performance gain?

Thanks,
Mr Gnome
