I'll stand by my i-Razr's for everything :metal:
but I'd be replacing them way too often if I rode on the highway too much!
as far as other recommendations...
+1 on the Turf Tamers, you can cut off a few knobs to make them better for trails
+1 on the Razr/Holeshot, great spacing for all around bite
Often overlooked are GBC Shredders, I think they've been renamed to Groundbusters. 4 or 6ply available. Very tightly spaced x-knobs for hard pack surface, they slide awesome. Decent on trails, but the tread does not clean out easily.
also, you should look into Fasttrekkers, I don't remember who makes them though
and these may be hard to find, but Pure Sport Bandits would be great for everything you described AMS has a new tire that's similar to the Shredders BKT has something similar to the Razr/Holeshot Duro has something similar to the i-Razr
If you can find a Duro tire that fits your rim, that might be your best bet for highway driving. Those tires’s last forever compared to itp/maxxis.Otherwise maxxis razr at $54 a tire might be cheaper alternative then some of the higher priced tires.
