Frequently asked
What tire size does a Suzuki RM-Z250 use?
GarageDex's powersports data shows the Suzuki RM-Z250 runs a 80/100-21 front tire and a 100/90-19 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 80/100-21 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 Suzuki RM-Z250 tire sizes change by year?
Yes - fitment differs across the years we cover: 2015-2023 runs 80/100-21 front / 100/90-19 rear; 2013-2014 runs 80/100-M, front / 100/90-M,19 rear; 2011-2012 runs 80/100-M,21 front / 100/90-M,19 rear; 2010 runs 80/0-21 front / 100/90-19 rear; 2009 runs 80/90-M,21 front / 100/90-M,19 rear; 2008 runs 90/90-21 front / 100/90-19 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.
