My vote goes to the Losi eclipse red in the hot summer 90+ degrees and green anything under 90 degrees. They work well on wet, dry, hard packed, blue groove, loose loamy. They may not be the 100% perfect tire for every track but they will work where other tires may work on just 1 type of track. Then there's the Truhe secret - if you want or need more steering then go to the red or green Losi xbt tread in the front. So far I haven't founda track where the eclipse don't do well.
