	TRX's are a metric sized wheel/tire that are not compatable with 
standard (15", 16",etc.) sizes.  So Michelin and, maybe Avon are the only 
ones that still sell them (read: expensive).  About 15 years ago, they were 
considered a good performance tire, but not by todays standards.  They were 
also available on a few other makes--a couple of Fords had them, also.  If 
you want to change to any other type of modern tire you'll need to change 
wheels also, which in most cases is a better deal anyway.  TRX's cost almost 
twice what a good performance 15" or 16" tire costs these days.  You say 
yours are brand new--if you're happy with their performance, I'd just stick 
with them until they need replacement.  When they wear or if you want more 
performance, you could find some used standard size wheels from another BMW.  
The last time I checked, that size TRX cost about $170 ea., on the other 
hand, a 225/50 ZR 16" Dunlop SP Sport 8000 cost about $85 ea. from the Tire 
Rack.  The Dunlop is a FAR superior tire in every aspect except maybe snow, 
which is why I keep my old set of TRX wheels/tires in the basement until 
winter.

Good Luck,
