I am still new to 1/12 and am working on figuring it all out. I just inherited a few lightly used sets of tires and need to get them matched up on my truer. I am running a lowered CRC pod and the IRS front arms on an otherwise stock 12L4. Here are the diameters of the tires I have. Any suggestions on how to pair them up and what diameter to true them down to? I assume I want to pair all the largest tires up to get the most life out of them, but do I want to run any difference between front and rear?
