Bought these tires from Motosport and on the description it stated that the rear tire is a BIAS tire. I installed the tires and had a severe wobble at interstate speed and at that speed you hold onto your you know what until you slow down enough to stop the wobble. While taking the tires off I noticed it saying Tubless Radial in small lettering on the rear tire and my Victory Kingpin can only have Bias due to weight and size of side walls the tires have. I have since installed the Dunlops that are true Bias tires and have no wobble of any kind. I returned the tires to Motosport and did receive my money back on the tires but not on the $150.00 for putting the tires on and taking them off the rims as promissed my Motosport. I have tried calling customer service several times and get no response or call back as promissed also. One thing for sure - when you are out $150.00 becuase of a companies mistake you make sure not to recommend them or buy from them again.
