I agree with that statement, as the Solar HP430 Tires that were originally on the car when I bought it would HOWL at both 20 and 40 MPH, almost to the point where the Radio would have to be cranked close to the Max to drown it out! (as of this post, I have since replaced them with a set of VERY Gently used (with less than 100 miles on them!) Cooper CS4 Touring Tires with a size of 185/70/R14 to the tune of $296; the Tires WOULD have cost me a Mind Numbing $506 if I bought them new and in the Proper size at Sears!) those new Tires i just put on are MUCH quieter, and the taller aspect ratio means I have a bit more Ground Clearance, as well as the ScootaDrive doesn't have to work as hard at cruising speed!
