18" tire options

Yes, you’re right!
Schwalbe Marathon Plus HS 348, size18 x 1,35 or ETRTO 35-355
(Kojak would be 32-355)

The last model year of this tyre was obviously 2013, you may also refer to the Schwalbe Part Nr. 114488.

So far it looks like this rarity is still available in Europe:

Just the cheapest local shop is out of stock…

I do have both tyres here and compared them…honestly, I can’t find that much difference, the rubber mixture might be variable and the profile is at the first look completely equal…there must be a pic somewhere in the forum, but I couldn’t find it quick…

Kojak’s are everywhere relatively expensive…(I believe…)

Edit: Out of curiosity, I took a look on the Austrian post calculator, Marathon’s and a scale…
Should be ~ 82 US$ shipped, incl. PP fee, for a pair (the long way - 10-15 days, no tracking).

Hope you can find a better offer locally :unamused:

Thanks BSA,

I will keep looking to get the best price, but I might come asking if not :slight_smile:

Gladly tnprime :smiley:

Surely I’d appreciate if you’d come back…equal if for this reason or another :wink:

Edit: Here the comparison pics Thicker 18" wheels for SX

Welp,

hit some glass on the way home from the bakery this morning, and popped a flat, so I am out of commish and in the market.

Hm…sh…

Any chance to get (at least temporary) replacement by Kojaks locally?

I am going to try and patch for now, my internet searches on the Kojaks are slim to nothing in the US, or 52.00/ea on the Schwalbe NA site. There was a pair on ebay, but long gone.

Seems that price and availability for the Kojak is also much better in Europe:

All of those below ~ 34 $ :unamused:

But, did you see this:

Utah isn’t directly around the corner, but at least USA, no?

I’d also give it a try and ask them:

thanks BSA,

I think for the time being I am going to try and get a Kojak and two tubes here from a dealer I found. Thanks for the links!

Hi guys,

I used to have a pair of Kojaks but sold it because with the type of roads here in the Philippines it will be ripped to shreds.

A friend of mine rode 200kms with him on Kojaks and me on Innovas. His was punctured by a little glass shard smaller that a grain of rice.

So I sold mine from an extra wheel set. The Innovas are pretty reliable but I noticed that one tire has somewhat thin sidewalls from the other judging from pinching the tire. I would want to switch to Schwalbe. I’m just waiting for the tires to wear out.

Watch your local market and try to get them before they’re sold out :wink:

JFYI, I have recently tried IRC tire for BD-1 (which is not roadlite, this tire does not have specific name). 18 x 1.5, heavier than kojak, but very nice tire.

Hi, I am new to this site so excuse me if I am not making a proper use of the forum.
I have a question, I have just bought online a set of tyres (Schwalbe Black Jack 18x1.9) to give my Kojak a break as I am now using my Strida on rough terrains.
Is this option viable?
Please I need your help.

Daniel,

Hello Daniel,

welcome at Stridaforum!
Don’t worry, I’d say you’re totally right here :smiley:

Unfortunately is the biggest size which may (but must not) fit 18" x 1,5.
I’d recommend not to use sizes bigger than 18" x 1,35 (ETRTO 35-355).

As the Schwalbe Marathon isn’t any longer in production there’s nowadays just one alternative;
the Innova 18" x 1,35 (Strida original equipment).

I’d recommend that you cancel your order :frowning:

Best regards,

Chris

I just changed tire from Innova to Schwalbe 18’x1.5 .(without fender)
As the gap between the tire and the frames are only about 3-4mm for both front and rear, I’m a bit worried that the said tire may rub on the frames.

After riding for about 50 kilometers last Sunday, I checked the condition of the frames for any signs of rubbing from the tire. The front frame didn’t show any rubbing at all ,but the rear frame got a rubbing marks at the frame (exposing the bare aluminium frame) :cry:

My question is , Is it still safe to use the said tire knowing the there is a slight rubbing of the tire to the frame? Will it affect the frame thickness? What is the best option to prevent this rubbing of tire?
Is it due to weight issue(being the rear tire)? Or does it to do with tire pressure?

Please note that when I was using Innova tire (which is 18"x1.35) I had similar issues of rubbing to the fender screws, the reason why I removed the fenders for both front and rear.
Is it due to flexing of the aluminium frame when riding? My weight is only 75kgs. and it is below the maximum permissible weight capacity of Strida which is 100kgs.

I would like to hear your advise or comments.Thank you

Hello ar.rtotp,

welcome at Stridaforum :smiley:

I’d say the main issue is that the Strida was initially developed and manufactured for 16" wheels.
Just somebody noticed later that it is possible to use 18 rims with certain, relatively narrow tires…and that’s it.

As long as the the marks are minimal there will be no safety issue, I think.
But of course you’re wasting your power.

Sure it will - sooner or later.
My guess is later; the fine abrasive particles of street dust will need a long time to attack the frame significantly.

Using tires equal or below 1,35".

No…it’s just…too less space.

Yes, and more: The axles and the joints will also move (slightly).

Please imagine the most common bike frame, the diamond type:
The frame tubes could be seen as three triangles; one triangle created by the main frame tubes and two additional triangles for the rear axle.
Note that the corners of all three triangles are 100% stiff (not moveable)!
And now imagine a Strida frame:
It’s just one triangle and moreover that - the corners are flexible, all three in at least one direction!

If you take a look at Ming’s safety pages you’ll notice:

  • Don’t ride over stairs
  • Don’t stand up while pedaling
  • No wheelies

Why do you think they warn about doing things which a common diamond frame wouldn’t take care of?
Hmm…because they do know their own frame?

However…a while ago I’ve bought a few 18 x 1,35" Marathons, shortly before they were discontinued.
Of course you may have a pair of those; just pm me :wink:

My friend’s solution to the rubbing of 18"x1.5" tires is adjust the spokes of the wheel.

Hey guys, I recently saw these on Instagram and I am really interested:
8H185BOP-PA PACER
Panaracer Pacers compact 18x1.5
Question is where to get these in the USA?
Update: I found this retailer that ships to the US, ~$66 shipped for two, a little pricey
alexscycle.com/tyres-tires/c … mpact.html

Ok so I found these Panaracers on a site, they take paypal and the price isnt bad, 18x1.5 would fit the EVO?

global.rakuten.com/en/store/fuji … 125300442/

As you can see in this post; some Strider’s are using 1,5" width without having trouble.
I saw an 1,5 inch tyre life just one time, and this was touching the frame minimally.
It’ll be a game - either it fits or not

Somewhere I’ve mentioned a fitting Panaracer; the exact specification is:
Panaracer Minits Lite PT for BD-1 18 x 1,25 (32-355)
But it’s a slick…
http://www.alexscycle.com/tyres-tires/clinchers/bmx-en-2-3/panaracer-minits-pt-for-bd-1-18x1.25.html

Schwalbe Marathon 18 x 1,35 would fit 100%…

I found the marathon’s in 18x1.35" on ebay but $52.78 US? seriously? My wife would kill me if I spent that kinda bread on bike tires. That is the same price US as full sized auto tires with all the materials, engineering, manufacturing and safety requirements built in… something is odd here.
