Muni tires on the street

We’re heading for our first campout of the season this coming Memorial Day
weekend and, having not previously ridden muni, I was anxious to try an
off-road tire. So I bought a $7.99 Kenda cheapy tire (24x2.1) from a local
farm supply shop and installed it on my United uni this past weekend
figuring I’d get a chance to feel it out before hitting the trails at the
campground next weekend. When my boys and I delivered newspapers Sunday
morning, I found it was extremely difficult to ride the knobby on the
street, I kept listing to one side or the other and expended much more
effort than expected during the ride. I know there’s a combination of
things here: my inexperience (been riding 5 months), cheapy tire, knobby
on hard surface, tire air pressure (due to my weight, I was running 70
lbs. in the 40-65 psi tire), and possibly others. After half the paper
route, I quit and my boys finished their route without me. The campgrounds
over the summer will have both paved roads and woodland trails and the
obvious solution is to obtain a municycle which will happen someday. I’m
open to instruction and learning here.

Thanks all, Bruce Edwards http://move.to/daup

Hi Bruce,

It’s probably the tread on the tyre. If there are knobs along the
centre line, it can cause you to lean to one side or the other. “Arnold
the Aardvark” suffered this fate recently - he changed his tyre and is
much happier these days. The extra effort would be from constantly
fighting the lean.

Mark,

Exactly the tire! Who has the website with the comparative list of tires?
Maybe that would help. Who is Arnold?

That’ll be Neil Dunlop. http://www.wobbling.unicyclist.com/Tyres/

Arnold the Aardvark is the pseudonym of Alan Chambers. Sorry, Alan, just
blown your cover. He has been known to post here. World famous for his,
er, unplanned dismounts. :wink:

Bruce, I hope this gets to you. I’m having some difficulties posting to
the newsgroup. Could you post this message up for the benefit of the
world? If you have any other questions please send me an e-mail.

I have this tire and it’s actually pretty good. It has no centre tread
but the knobs are relatively big, allowing you to kick out mud and snow.
Look at the

tread pattern and see if it’s the same as the Kenda Black Smoke 2.1-inch
knobby tire. There’s a nice picture from:

http://www.unicyclesource.com/Kenda_Off-Road_Tires27968.html

I’m surprised the tire’s so cheap. I paid 50% more and unicyclesource.com
sells it for $10.

If this is your tire, then you’ll just have to build up your leg
muscles and

learn to ride with it. Using a knobby on pavement will have so much more
friction than a slick, which means you’ll have to work that much harder on
your paper route. You could try to get a less aggressive knobby tire, used
for dry dirt, but you’ll have the same difficulty. Knobbies take more
muscle. The payback is on dirt/mud, where your slick will slip and slide
and your knobby will grip.

Also you may have moved from a standard 1.75" width to a 2.1" width.
That’s a 20% width increase of your tire, so you have much more rubber on
the road. When you compress the tire with your weight you’ll get an even
bigger footprint. This larger footprint is great for off-road, because
you’ll get so much more grip.

The solution to the problem:

  1. Get 2 unis: One for road, one for offroad
  2. Use one uni but suffer a little either way (pavement or offroad). Pump
    it up more for pavement (90 psi) and less for off-road (40 psi)
  3. Use one uni but change your tire frequently (pain in the ***)

P.S. A friend also has this tire and has pumped his to 90 psi without
problem. He rode it all winter. Check out my tire page at
