RCcoachworks 59 Posted July 12, 2018 I am trying to figure out when some tires I have were produced based on their packaging. I'm not sure when these are from, but the Y6001 part number makes me think they're vintage, as well as the yellowed/dusty bag. Any thoughts? I'm just trying to determine if these are truly from the early days or not. Share this post Link to post Share on other sites
frameskip 63 Posted July 13, 2018 My understanding is that the “Y” and “X” part numbers are the MRC part numbers for when they were the US Tamiya distributor. These look like original spare parts to me. Share this post Link to post Share on other sites
RCcoachworks 59 Posted July 14, 2018 Thanks for the info. That makes sense - all the MRC Tamiya part bags I have also have the same type of part number, X#### and Y####. Share this post Link to post Share on other sites
