It all depends on how you drive, and what tires you Titan was equipped with. I came with The Bfgoodrich Rugged Trailer, and they lasted me about 20,000 miles (under a year), I switch to 18 rims with SRA's and the tires already had about 15,000 on the tire and I put another 9,000 and I need to be replaced soon, the tries wore our unevenly I get the rotated every 3000 miles because of the amount of driving I do
