Can all 700c rims accomodate a 700x32c tire?
 
I would like to go from a 700x23c on my fixed gear bike to a tire that can use substantially lower tire pressure since my new route has some rough pavement and I have to use sidewalks (with those annoying relief cracks!) occasionally.

Panaracer makes a fairly lightweight 700x32c tire. Will this fit my standard 36h 700c rim?

Measure the inside width between the beaded edges of the rim. If 14 mm or less then a 28mm tire is the widest normally recommended. If wider then a 32mm tire is fine. ISO/ETRTO recommendations are the tire should be 1.45x to 2x the rim bead width normally though people do regularly exceed the recommendations at both ends. Too wide a tire may not be adequately supported by the rim, givin a wierd feel when cornering, and too narrow a tire for the rim risks pinch flats.

The other thing to check is the frame clearance both at the front of the chainstays and at the seatstay cross brace/rear brake mount to make sure the frame has clearance for the wider tires. In front check clearances at the top of the fork, both vertically and side to side. Many road frames and true track frames do not have adequate clearances for appreciably wider tires.

I ran 32's on a narrow velocity deep-v rim for cyclocross. I also ran 23mm tubes because that was all I could get in long stem.

for 14mm internal width rims, you can put on 32mm tires no problem. usually you can go internal width x2.5 and be safe.

for 15mm internal width, most mavic road rims, 32mm is no big deal

I use 32mm (that actually measure 33) clinchers on my Mavic Open Pro rims and they fit just fine. I doubt your rims are narrower.

If it fit the 23c's fine, and you have clerance from the frame/brakes for 32c's you'll be fine. Depending on the exact '32c' you installl, it'll vary. How about telling us which frame you have?

short answer is probably. since it's a fixed gear, it is probably using a sportier frame which may have clearance issues with the 32s. you may want to just get some 28s and be done with it.

As others have said, it's likely that you can fit the 700-32 tire onto the rim you are using. The question then becomes can you fit said rim and tire combination into your rear triangle and into the dropouts with the tire fully inflated. Fixed gear bikes have horizontal dropouts that face to the rear or angled slightly down towards the front (old style campy dropout). My 1981 Ciocc road bike has horizontal dropouts facing towards the front, and I tried a Panaracer Pasela 700-32 on a Mavic MA2 rim and it would not fit (tire hit in back of the chainstay support). 700-28 fit fine.

I run 32mm Schwalbe Marathon pluses on the same rim - but for a heavy commuter. Probably went 6000 miles before my first flat.
