All about Tires!

For those of you that run gold compound is there a certain tire sauce you like? blue dot and devil spit work well on M4s or green here, but the golds don't seem to "take" much of the stuff, it just sits on top.

To keep from traction rolling and promote pushing on sweepers some electrical tape can be a quick fix on the outside rib of the front tires before making a big setup change. Does not help ballooning. Takes the snap out of a 2wd sc10. Maybe some heavy braid fishing line wrapped around. Going to practice tommarow will throw some in the box.
Try some Short Course Buggy tires and rims on the front of your SC10 works great. The SC buggy tires and rims are narrower than the SC10's.

Track surfaces are all a little different, somewhat difficult to make broad assumptions for all tracks. But in general loose dirt conditions require a larger pin tire, to dig through the loose stuff. Hard packed blue groove tracks need a short pin/bar tread to prevent the pins from folding over.
Lower traction hard packed tracks generally need a softer compound and perhaps softer foams (white open cell) to help get grip. Higher traction tracks a little harder compound and stiffer foam (molded closed cell) to prevent excessive tire deflection at the higher cornering speed and load.
Similarly rough tracks generally need softer foam to better absorb the bumps and maintain contact. The stiffer molded foams work better on smoother tracks, provide better control at the generally higher speeds.
Temperature impacts rubber and tire stiffness, and wear. Really hot conditions a soft tire can get too flexible and wear really fast, consider a harder compound. Opposite for cold.
Clay tracks, moisture can really change. Some clay when wet slicks are the best. As they dry out a little more pin/tread is needed, sometimes so called ‘ghost’ pins, then broken in or sanded, up to new or newish clay tread tires as the clay dries out.
Again, tracks are different, the best advice will almost always be from the locals that are most familiar with the particular track, and likely have tried many setups.
