LBM,
Lewis Campbell (limylou) has used the Airfree tires on his GRR for a couple of years. He has been very happy with them and tells everyone so. There are a couple different compounds (compressions), and at least two mfgs. I understant that the HR compound from Airfree Tires is much better. But to each his own. And please don't assume everyone with a good comment is spamming. Hugh Waters, the owner of Airfree Tires posts regularly to the ARBR usenet group. And Hugh Doesn't spam. He responds to questions. I am waiting for the new Open Road recumbent tires (20/26) to hit the shelf.
