What do the tire numbers mean?
A size like 120/70-R19 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 BMW R 1200 GS tire sizes change by year?
Yes - fitment differs across the years we cover: 2018-2019 runs 120/70-R19 front / 170/60-R17 rear; 2017 runs 120/70-19 front / 170/60-17 rear; 2014-2016 runs 120/70-R19 front / 170/60-R17 rear; 2013 runs 120/70-19 front / 170/60-17 rear; 2010-2012 runs 110/80-R19 front / 150/70-R17 rear; 2008-2009 runs 110/80-19 front / 150/70-17 rear; 2006 runs 110/80-R19 front / 150/70-R17 rear; 2004-2005 runs 110/80-ZR19 front / 150/70-ZR17 rear.

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.
