Tire widths on wide rims

Some of the tires I used a scaling caliper and some I used a square with MM markings and a CD case. The square with CD case worked quite well, just put the square against the tire, slide the CD case (or any square cornered object) down the edge of the square untill it touches the tire and read the measurement.

I did all my measurements 3 times on difrent parts of the tire and used the average.

If you don’t have a square I am sure you could make a pretty decent one with two rulers and some glue.

oh yah, forgot I gave my measurements in inches, I devided by 25.4 to get inches so I could compare to what they were “suposed” to be.

Intense 26" DH FROlite, SR 50, folding bead, 12psi, ridden ~60hours
Koxx K1, drilled, 47mm

2 5/8" widest point, measured edge to edge from outsides of knobbies
2 1/4" tallest point, measured from rim edge to tallest knobby

Notice how close it is in width to a 3" wide duro, and it’s firmer at low pressures, has stickier rubber, and the knobbie are symetrical.

Anyone have a Gazz Jr for comparison?

swapped out my 29" tire. After about 100km of use the Schwable RR 2.4 stretched another 3mm to end up at 2.60" wide on my 50mm rims and the WTB ExiWolf 2.3 that I just put on came out to 2.36"

Can small wheels play too?

20" x 1.95 Kizumbut on a 47mm rim. Tire inflated to 40 psi brand new barely rideen. 57mm (2 1/4")

Kenda Blue Groove 26" 2.5 - 62/559 folding bead version on new 26" Qu-Ax MUni rim “DB 26 X”, 40mm wide, at arround 18psi and 100km of riding: 62mm. Tread is widest.

Just mounted my Intense edge 2.5 on my dx-32. No riding yet, but it measures 61mm at the casing and 65 mm at the tread.

I measured the Kenda Telonix 2.4 before I took it off and it also had a 61mm casing and 63mm at the tread.

Racing Ralph 29 x 2.4 Evo mounted on KH 29 x 47mm = 2 9/16"

Hey Max, did you score on of the FROlite with sticky rubber?

Let us know what you think. You should look at gettin a wider rim, it’d spread the tire out…

No, they were out of stock on the sale priced 2.5’s, so I got a FR (dual compound, 2 ply sidewall) version. But when I looked last night, they had the cheap sticky 2.5’s again. Oh well, it should last a little longer.

tubeless is a conversion you do to make your tires run without tubes they are a little hard to do you can get kits http://www.notubes.com/tubeless_system.php?cPath=21_58
with tubeless you don;t get pinch flats, i have run over nails and a re-bar once and my tire went flat then i spun the tire around a couple of times and then i used my trial pump and it was holding air so i rode back to the truck i do not recommend running a patched tire for long so if you run over something replace your tire asap

WTB Stout 29 x 2.3 on a 47mm KH FR Rim = 2.25" case, 2.4" tread
Duro Wildlife 26 x 3 on a LM 65mm = 2.8"
Intense DH 26 x 2.5 Frolite SR 50 on a 47mm K1 = 2.5"

Notice that the Intense DH 2.5 was actually narrower on the LM rim. This seems to result from the tire being stretched too wide, so the sidewalls pulled in and made the tire cross section narrower.

So I decided to put a true 3’ tire on the LM and keep the 2.5 for the narrower rims; yeah, like 47mm is narrow :wink:

My muni stable is getting outta hand:
Ti 26 x 2.5
Surly 26 x 3
KH 29 x 2.5
KH 36 x 2.5

My son:

Just sold a Nimbus II 24" Freestyle, so I guess that’ll make some room… :slight_smile:

Dang Nurse Ben you have so many sexy unicycles :astonished:

Continental Trail King 2.4 (Folding, Black Chili; ~50mi use) on 47mm Trialtech Race rim @ 20 PSI = 2.6"

Continental Trail King 26x2.4 (Folding, Black Chili; ~50mi use) on 47mm Trialtech Race rim @ 20 PSI = 2.6"

WTB Wolverine 29x2.2 (Wire bead; ~10mi use) on 47mm KH rim @ 20 PSI = 2.4"

Schwalbe Hans Dampf 29x2.35 (Folding, Pacestar; new) 47mm KH rim @ 20 PSI = 2.4"

I was a little surprised the casing didn’t measure significantly wider than the wire bead Wolverine 2.2 but the Hans does weigh about 100g less and should offer much improved grip; both good things.
