In looking at the newly positioned Super V-Lite and Ultra Windjammers, especially the 26VFK / 2618VS, I noticed that they no longer have the 15" wheels of the bigger units. By my calculations, the 205/14C tires are right up against the maximum tire weight limits (just under 7000 lb gross on the axles = 1750 lb per tire). If they were 15" I could upgrade to D range, but I guess Kumho would be the only option in the 14" size. Since these units previously had 15's, I asked my dealer if they could be ordered with the larger wheels. He said he'd have to check and I haven't yet gotten an answer, but this could be a deal breaker for me, even though we really like the model. Am I missing a fix?
