Frequently asked
What tire size does a Yamaha YBR250 use?
GarageDex's powersports data shows the Yamaha YBR250 runs a 100/80-M17 front tire and a 130/70-M17 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 100/80-M17 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 Yamaha YBR250 tire sizes change by year?
Yes - fitment differs across the years we cover: 2011 runs 100/80-M17 front / 130/70-M17 rear; 2008-2009 runs 100/80-M17 front / 130/70-M17 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.
