Mountain Biking - Weight Wienied My Tires....Help

OK. I am not a weight wienie but i just went to weightwienie's (http://weightweenies.starbike.com/listings/components.php?type=mtbtyres) and found out my tire (Bontrager connection OEM) ways as much as a 32 oz beer. Man that is heavy.

Can someone recommend a good tire that weighs closer to what a can of beer weighs?

1. Don't want much tread. Semi-slicks would be good.

2. Want tread to last a little while so don't want race tires that burn up fast.

3. Under $30 per tire.

Ritchey Elevader is a rear specific tire. costs me 10 dollars and 5 to ship on ebay. Its sitll there, frm Bens Cycles.
Ritchey Excavader is from nashbar and costs 17.95. Both are something like 500 grams, which isnt too shabby.

I think that has more tread than i want. I am looking for low rolling resistance. A semi-slick with knobs on the sides maybe.

TOO MUCH TREAD

semi slicks suck. Ritchey does have them though.

check out the holly roller, it rolls smooth and still has some good traction.
And they don't weigh as much as that beer. Beer is fluid ounces and those tires are just ounces. I don't know how much a 32 oz. beer weighs though, but those tires probably weigh more than that beer.

Not quite a semi-slick, but the center tread looks pretty thin. Claimed weight of 630 grams...
