Frequently asked
What tire size does a TM Racing SMX 450 Fi use?
GarageDex's powersports data shows the TM Racing SMX 450 Fi runs a 110/70-ZR17 front tire and a 150/60-ZR17 rear tire. Tire sizes vary by year - see the table for each range.
What do the tire numbers mean?
A size like 110/70-ZR17 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 TM Racing SMX 450 Fi tire sizes change by year?
Yes - fitment differs across the years we cover: 2019 runs 110/70-ZR17 front / 150/60-ZR17 rear; 2012 runs 110/70-ZR17 front / 150/60-ZR17 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.
