Was waiting from who I purchased my tires to resolve this but these people do not like talking to customers (AJParts, Fayetteville, GA. MY Arachnids were mounted by my dealer and are pulling left, this is the 4th set that the dealer has had trouble with. I do not like the Kendra's neither but had no choice but to put Kendra's back on my Trike. I purchased these tires through PayPal and at present time I am waiting their contact with AJ Parts concerning, I have an Arachnid on the rear and at 5,000 miles it is doing great, I suspect an out of round or bad mold on this batch of tires so make sure and check with the service department before buying. My dealer did check my alignment and all before telling me what the tire was doing...
