Did I do it or did *I* do it?
I'm 6'2" @ 270 lbs and just bought a new bike:
https://www.khsbicycles.com/06_urban_xtreme_07.htm
Until buying the KHS, I have been riding the same Bianchi for the last 20 years. Honestly though, except for the odd spin, I haven't seriously ridden the Bianchi for a number of years. Anyway, I decided it had been long enough and I decided I wanted a change from the mtb. I really enjoy riding the KHS, but I have always been a little unsure about riding anything less substantial than a mtb. Anyway, on the ride home from work last week I was making a left through an intersection while keeping an eye on the traffic behind me. Unfortunately my front tire found a deep crevice in the asphalt and I hit it pretty hard. Before I cleared the intersection the front tire was flat so I walked the rest of the way home. I changed the tire and the next morning replaced the wheel for the commute back to work... now the back tire is dead flat. I am positive only the front took the beating, but upon inspection the rear rim is dented and no longer true. I've fixed the flat on the rear, but I'm curious if a dent in the rim would require me to strike the rim or could my own weight have caused the damage? Both?
The bike is less than ten days old -- do I need to replace both rims? Just the rear? Can they be mixed?
(I see Deep V are recommended for the clydes)
Thanks in advance

Sounds like that crevasse sproinked your rim a tad. Have the LBS take a look at it. Weinmann double walls are, or at least used to be a pretty good rim! If you can recover it, go for it.
Not as strong as the Velocity Deep V, but still a decent rim.

Many bikes use a cheapo rim liner in the wheels. Make sure you get the 'Velox" rim strip. It's similar to medical tape. I've seen plenty of riders flat due to the rim strip moving to the side allowing the spoke holes to cause the flat (plastic and rubber). Velox has an adhesive backing. Check it out just to be safe. Rims strip is only like $5, well worth it!

I had a series of flats in my front that was due to crappy rim tape (strip), I've since replaced the rim tape with a thick cloth one, no problems since. I paid 5 dollars a rim.
To answer your other question yes you can replace a single rim at a time. Presently I have a stock rim on the rear and a new Mavic X317 on the front from a nasty taco. It looks a bit dorky, but I couldn't justify replacing the rear rim when it was (and still is) perfectly true.
