I just replaced 6 Michelin tires that I put 45,000 miles on in 8 years. I don't know how many miles the previous owner put on them but the DOT dated was 9 years ago March and there was absolutely no dry rot and still some good rubber remaining on them.
Although the Michelin served me very well I just didn’t think that I could afford them at this time so based on the many positive remarks on this forum and my truck services owner's (he does not sell tires) customers experience with them I went with Hankook for $249 per tire plus balancing, mounting and all taxes of $52.66 for a total of $301.67 per tire but know that I have 19.5” tires.
