So, I naievely thought that getting new tires was a simple thing. I'm super confused now about options, brands, ratings etc. We have a (very early) 2017 Aliner Scout (about 1,400lbs) with original tires "LOAD STAR" K550, Load range D, ST175/80 D 13. I don't know how long these tires should be good for but they have a "speed rating" of 65mph which is super annoying since it adds so much extra travel time. I am more concerned with the tires than anything else and would want the best quality I could get (with a single axle, blowouts is a huge concern for me, especially if I'm towing by myself). I guess my questions are...should I replace the tires I have? (I don't know how long they're good for or if this is a good tire or a bad one). If I should replace, what are the best brands that make a tire in this size? I read Michelin is one of the best makers but not sure they have a tire this size (which I think is 13"...is that right?). Obviously I don't know anything about tires really, just prefer them not made in China. Any advice here is appreciated, appointment is Friday! P.S. our Subaru's tires are almost bald and we need to replace them too, if anyone has a suggestion there as well that would be most welcome!
