Frequently asked
What tire size does a Harley-Davidson FLSTN Softail Deluxe use?
GarageDex's powersports data shows the Harley-Davidson FLSTN Softail Deluxe runs a MT90-16 front tire and a MU85-B16 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like MT90-16 reads as tread width (mm) / aspect ratio (% of width) - rim diameter (in). Match all three so the tire fits the rim and clears the swingarm and fender.
Do the Harley-Davidson FLSTN Softail Deluxe tire sizes change by year?
Yes - fitment differs across the years we cover: 2009-2012 runs MT90-16 front / MU85-B16 rear; 2008 runs 90/16-MT front / 85/16-MU rear; 2006-2007 runs MT90-B16 front / MU85-B16 rear. Match your exact year in the table.
Can I fit a different tire size?
Stick to the stock size - it's matched to the rim width, speedometer, and handling. A wider tire can rub the swingarm or fender and throws off the speedo, so only deviate on a shop's advice.
