Frequently asked
What tire size does a Triumph Tiger 900 use?
GarageDex's powersports data shows the Triumph Tiger 900 runs a 110/90-19 front tire and a 150/70-R17 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 110/90-19 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 Triumph Tiger 900 tire sizes change by year?
Yes - fitment differs across the years we cover: 1999 runs 110/90-19 front / 150/70-R17 rear; 1998 runs 100/80-19 front / 140/80-17 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.
