3.0 Good tire

I've actually had these 40x13.50/17's for about 6 years. On a not often driven truck. Actually looking at prices for adding a spare and figured I'd leave a review. These are good tires. Excellent road manners, low noise and handle wet roads great. The reason I don't say awesome tires or give 5 stars . They simply don't balance out well at all. The amount of time and effort spent trying to balance them is ridiculous. Simply far from truly round.
