Solid tires on 2006 Sonata LX
 

Thought they quit making solid tires in about 1909. My LX with the 17 inch
wheels rides like it has solid tires. feel every pebble in the road. do
the GLS's with 16 inch wheels ride smoother? Back seat rides like a
lumberwagon. I traded in a '99 merc Grand Marquis that got 30 MPG on
highway with a V-8 for this thing and it rode smoother-quieter. still
trying to get 30 MPG with this Sonata..Oh well I have it now and would
lose a ton if I get rid of it!
