[Closed] Maxxis LUST.... UST rim compatible?

saw this link ( http://nextdaytyres.co.uk/search.aspx/TYRES-UST) yesterday and i finally looked at it today and it got me thinking....

are LUST tyres the same as UST tyres?

have Deemax rims and tried setting them up tubeless with HRII EXOs, but they would burp too easily from the rim.

I know there are some UST tyres from Maxxis, but they are over 1.1kg and that is a bit of a weight penalty...

now the Ardents ( http://nextdaytyres.co.uk/details.aspx?GroupID=22&Matches=388&Desc=UST%20Tubeless%20Tyres) are listed as being LUST, but are on the UST tyre list. ~800gr for a UST tyre sounds ok. have ridden Ardents before and they are not a bad tyre.

cheers in advance...
