Depends.

It's usually used for cotton, which doesn't offer much protection no matter how dense the weave is.

A lot of times the higher TPI can handle higher inflation pressures but thats really all. If you want puncture resistance look for tires with kevlar puncture resistance, or get a tire liner. Better to just learn how to fix your flats fast and avoid hazardous terrain as much as possible or "get light" when going over bad areas.

Keep in mind a huge percentage of flats result from snake-bite, which is not really going to be helped by puncture proof tires anyway, but many rims are designed to help with that problem.

with some mountain bike tires like Maxxis the higher TPI the lighter the tire can be made. With the thinner threads used in a high tpi tire the sidewall can be made thinner for a lighter and more supple tires.
Maxxis uses a 60 tpi for a good all around tougher tire that will last longer.
the 120 tpi tires are made "race day only" much lighter - lower (62) durometer rubber for much better grip and traction - the trade off is they wear out quick - in 1000 to 1500 miles.

I don't know how it works in road tires.

Higher TPI tires tend to offer a much much smoother ride, as well. When i had my Allez, I went from the 60tpi stock tires to 127tpi Michelin Krylion Carbon (awesome tires, wish they made them in 28c for my hybrid), and the difference was amazing. Less felt buzz, more solid handling, faster, and both Krylion tires weighed about as much as one of the stock Specialized tires...

Snake-bite is very easy to prevent: Inflate your tires properly! I used to run about 35psi in my mountain bike tires, offroad that is. I run about 55 now for the crushed limestone trails I ride. My 700x28c tires on my hybrid get 115/120 F/R.

Michelin needs to release a 700x28c Krylion Carbon tire...I would buy two...

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

It's like buying better bedsheets. More tpi translates to a thinner more pliable fabric. On tires, that translates to a thinner more supple wall for more comfort and rolling efficiency. In some cases more tpi can mean more strength so it's common in better higher pressure tires, but usually this is more related to better quality thread, than the tpi per se.

No offense, but Michelin Krylions are not in the same league as Challenge or Vittoria open tubulars (clinchers that have the same casing as the corresponding tubulars). The current Vittorias are 320 tpi, and Challenge makes several models with 250+ tpi. If you want superior ride quality in a wide road tire, try the Challenge Parigi-Roubaix. It's 700 x 27c (in reality its about 30mm wide), 260tpi. Unbelievable ride quality. Here's a pair on my "day tourer."
