Anybody know if they'll fit? Pat?

So long as they're both 8-lug, yes. They didn't change the pattern until '10.

No problems with caliper clearance or anything like that?

Another related question - Are wheels that have TPMS different than those that don't have it?

Don't know about the calipers or not, seems like the '07+ went to bigger brakes, so there might be an issue. As for the TPMs, no, there is no difference. GM TPMs just screw onto the bottom of a valve stem, which has the same sealing surface as your regular rubber valve stem

Patgizz was able to fit those GMT400 8 lug steelies on his Avalanche before he gave up on it. I found this in an old post:

i believe the smallest you can go is 17" on the newer platform for brake clearance. newer trucks are getting huge brakes.

^what he said. 2005ish and newer got 13" front rotors and required 17" wheels to clear.

Actually, that was for 1500. Just noticed you asked 2500. Sorry.

then you should be good. bolt pattern changed in 11 or 12 to metric. 08 still 8x6.5. i'm finding conflicting info on the brake size change year but if you have 16's now, the older ones will work.
