For road riding, what tire width are people here using?

IIRC, Andrew is running 23mm tubulars. On my single bikes, I'm using
either 28 or 32mm, and 35mm on the folding Bike Friday with 20" wheels
(AKA 35-406).

Is anyone using road tires wider than 32mm?

None of my bikes are pure road bikes though my commute bike ie the bike i
use on roads the most I use 50mm tires could clearly run thinner tires but
seems little reason to do so.

28/30mm would seem to be common looking around the club and other roadies.

I once built myself a tandem frame and mounted the then-new
Vittoria 'open tubulars'* in 700-30 on SuperChampion #58.
Sold it in 1978 so I did actually own fat tires briefly.

*As I recall they were the first folding kevlar bead tires.

Testing hasd shown the normal fat American to have the least tiire friction from 30-32mm tires but unless you have a gravel or touring bike such sires won't fit in a road bike. Most people are presently using 28's.

Giant TCR road race bike, ie pointy end will fit 33mm ie CX tires and have
done for number of years.

Ie road bikes even ones with racy aims and geometry have gained tire
clearances.

No technical reason not to, compared to older bikes with much more narrow
clearances which where based on iffy science, if at all!

My brother has a Giant TCR and it won't mount anything wider than a 28. Perhaps you're talking abouit the Giant cyclocross bike? Perhaps they are also called a TCR?

CX tires are squared off on the top. I've seen 28 mm tires on some rims that measured 30 mm but I never measured them myself. All of the wheels I have do not expand beyong the rims. But these are 21 mm inside wall width rims. I did buy a set of Campagnolo rims that are supposed to be 24 mm but the tires seemed to not expand outside the rim as much.

Older ones very probably like with most bike brands, but latest model
claims 33mm max size and seems to have been 32 going back number of years,
but broadly speaking all road bikes have increased their tire clearance
over last 10 years or so.

Most companies are a bit conservative with frame clearances though off road
do need to keep some mud clearance space, on road can get much closer.

I have an early 2000's TCR Team. There isn't much clearance in the rear
for anything larger than a 28. Newer TCR models have much more room.

I use 28 Conti GP 5000s on my disk brake bike and 25 on the rim brake. I
could go to 28 for it but no need really. I don't like riding on any
gravel.
