I have a 2006 2500 avy . I bought new bridgestone duravis 773 tires because other tires were gone. I installed same tireshat came with truck .these new tires felt very squirly. I tow one a year but its 2000 miles . I have heard the michelin ltx ms2 were a good solid towing tire . I need help with this .I tow with a hensley so I'm setup for antisway . But the bridgestones just don't feel right . They almost feel like there not enough air in the tire but it is. Thanks for any advise.
