Not unlike other brands, I've heard that older Panaracer Pasela tires ran slim when compared to their advertised width, probably a marketing ploy to get the weight down for its size - but I've also heard and read (on the internets..) that recent production has changed such that the widths are wider, more true to spec.

The cool thing about the Paselas is that they come in so many sizes. That's also the bad thing - none of the local bike shops carry them. I'm trying to determine the widest tire I can fit in my bike. Anyone out there with Paselas on your bike, can you report the width of the tire at its widest point, along with the spec'd width? Even better would be someone with the Pasela TG 700c x 28 - the size I'm aiming for - that would more than awesome.

I just got an email from Harris Cyclery, and they said the plain Paselas (no Tour Guard etc.) run "pretty true to width". Didn't get any measurements from them, though, and i don't have any Paselas myself. I use 28 mm Panaracer Rolly Poly tires, and will soon be getting a set of 28 mm Grand Bois Cerf.

Would be nice to have a webpage of true width measurements of various popular tires on various popular rims.

My plain black Pasela 700X32C tire measures only about 29mm on a fairly standard road rim. Had it a couple of years, so it may be older production.

I'm decidedly a non-expert, but the following opinion is based on my experience with tires for other types of vehicles.

One thing that might be a factor in determining the correct tire width (for any tire) is the rim width. To match the tire width specified by manufacturer you have to have rims with the same width as the reference rim they use. If your rim is wider, then the tire will inflate slightly wider (the side walls will bulge out further, and the contact patch will widen as well), a narrower rim gives you a narrower tire.

To get a feel for how this works, in the extreme (for snow bikes), Surly Large Marge rims are 65mm wide and are typically used with Surly Endomorph tires that are 3.7" wide, but another company, Chain Reaction Cycles sells a 100mm wide rim for use with the same tires. The reason for the added width is because it adds volume to the tire and actually makes the contact patch wider, a useful benefit when you are trying to float over snow.

Thanks for the reply. I think you're right, rim width is important but I think my wheels will fit the tires without a problem. What concerns me is tread clearance in my road bike's center pull brakes. I'm trying to find the wides tire I can fit without having to change out my brakes to something like cantilevers. – Sk606 Jan 4 '11 at 4:54

The trouble I'm having on 2 totally differnt bikes is that the tire diameter is too large!

First a pout replacement panaracers on an old Miyata 27" bike and found that there is not enough clearence to the top of the fork and espcially the brake. I wrote that off to the age of the Miyata and the fact that it is a small (women's) size.

But now I have builta brand new road bike using Nashbar frame. And these new Panaracer tires have about 1/10th inch clearance to the frame member where the brear brake mounts. Even less to the brake body! This is not going to be usuable ayt all. I measures the thickness of rim + tire with these Panaracers (700x28) compared to regular Michelin 700x23 on identical rims. The Panaracer is indeed over 1/4" more in an already tight fit (depending on the frame).

I have thought of making somke kind of braket to move the brake body higher. But what is REALLY needed for these tires on my bikes is a spacer in the frame dropout. That part does not exist, but I could maybe make it. SInce the dropout os a slot, there is a little room for correction there.
