I swapped out my front tire at 13,000 on my '15 Triglide. I could have got about 1000 more miles, but I didn't want to be on a road trip needing a tire. I also wanted to try the new Avon Trike front tire and that has to be special ordered. As far as the rear tires go, I swapped them out at about 75,000 on my '09 Triglide.
Can any 2015 Triglide owners tell me what mileage I should expect to get on the front and rear tires of a Triglide?
Depending on how I ride I will get anywhere between 8,000 to 15,000 out of a front tire.
Rear tires have lasted me around 40,000 miles. That includes a lot of hard riding though. I imagine staying all on nice roads, and refraining from burn-outs, one might get 50 or 60,000 out of the rears.
