Well I have used up 24 tires on my dualie-plus 6 more that have about 10,000 (od says 110,000)left on them. Have tried all brands. Tow 13,000 lbs and have heavy (size 14) right foot. Should I spend the Mucho Bucks and spring for 19. 5's and who's. Anybody have any l o n g term updates on dodges and 19. 5's?
