You can see by the photos that only really thick tire liners will allow you to keep on riding long after the tire tread is worn out.

I just wish I could find a tire with steel impregnated rubber treads for my utility bike. DOES NOT ANY ONE MAKE A TIRE WITH SCINTILLATED RUBBER????



and the newest one:



this is what started this bulge a puncture that would have left anyone else stranded.

Is there any good reason that you are riding on worn out tyres?

Are your tyres correctly inflated. Good and hard tyres tend not to pick up grit and flints, or even shards of broken glass... I know this from many years of urban riding experience.

Also if you are running proper slicks, or semi slicks you can make and fit a tyre scraper/wipers to remove the majority of the nasty foreign objects before they have done one full revolution of the wheel. https://janheine.wordpress.com/2012/...f-tire-wipers/

I am running fully inflated semi slicks or full slicks on all my bicycles these days including my utility bicycle, trailer and pedi-van. There is considerably less rolling resistance and there is no appreciable lose of either traction and braking efficiency... even under load on wet tarmac surfaces.

Dude, tires are made to wear out. Suck it up and buy new ones.

FWIW The Finnish Company ..Suomi Nokian makes utility tires with a quite hard, long wearing, Rubber compound..

grit?. like True Grit ? https://www.imdb.com/title/tt0065126/ with Marion Mitchell Morrison.

well I can see you folks have no imagination. possibly even antagonistic for what reason? I just want tire that last a hell of a lot longer than the usual industry rip offs. I carry a lot weight on my bike and am sick n tired of disposing tire every year. It is a waste of good materials and therefor money.

I keep my tires inflated to a safe level, that's why I was using BMX tires. A waste of money. Humbug!

Leebo

Well, help us out some. Bike weight, rider weight, rims used, tires used? They make some harder compound tires. Schwalbe marathons come to mind. Lots of choices there. And yes, tires do wear out.

chriskmurray

Time to invest in better quality tires if you want them to last. The Schwalbe Marathons are known to run for around 10k miles on the rear for a lot of riders. If you want to go a little cheaper I have had great luck with the Panaracer Crosstown which can be found much cheaper.

If your budget is tight try some Michelin tires. They usually cost significantly less than Schwalbe, Specialized and comparably durable commuter/utility tires. I've been riding a set of Michelin Protek Cross Max all terrain tires for almost three months and they appear to be very long wearing. Even the mold release nibs are still there - very tough tread. Yet the tires also grip really well, dry and wet - I couldn't get them to skid on wet grass; the tires dug in down to the dirt. The Protek Max tires have a 5mm puncture resistant liner molded in - so far, so good, no punctures on the same roads and unpaved trails and fields where I got four flats in one month last fall running Specialized Hemispheres with a thinner puncture resistant liner.

The only downside I've personally experienced:

• These tires are heavy, around 1,100 gr apiece, but this isn't a problem for most utility and casual riding.
• The ride feel is harder than the Specialized tires at the recommended pressure for my weight. But reducing the pressure a bit gave a more comfortable ride without any noticeable increase in riding effort. I weigh 165 lbs and run mine around 60-65 psi, a bit less than the maximum 76 psi suggested for my weight, but this seems to suit my mix of smooth and rough pavement, and occasional gravel roads. I've ridden them a few times around 50-55 psi on lumpy grass fields and pastures, no problems or pinch flats.
• The sharp shoulder of the raised tread feels just a bit squirmy on hard, fast cornering, and I can hear 'em squeaking just a bit. The tires didn't slip or feel like they might, it was just a slightly squirmy feel. This will soften as the tires wear, and I don't often make curves that fast. I only noticed it during test rides when I deliberately pushed it harder, and on a couple of rides with tricky left hand turns across intersections.

A couple of customer anecdotes complained about sidewall failure with Michelin City Tires after about a year, but in both complaints I read the users said they ran higher than recommended pressures (another bike forum member said he ran them over 100 psi, while Michelin recommends a maximum of 87 psi). I haven't ridden the tires long enough to have any opinion on long term reliability.

WELL THE total combined WEIGHT IS AROUND 400LBS WITH CARGO AND MY OWN FAT ASS. I have tried a lot of tires, 20" x 2" is hard to find. Infact the big apple looks good but at 65psi not . yes marathon tires could be better, but I ran out of patients with them when their tires cracked open....I would love to try Armadillo tires but they don't make them small enough.

"Protek Max tires have a 5mm puncture resistant liner" like the marathon plus???? I don't trust tires unless they can handle at least 75psi.

The only puncture resistant liners worth using are extra tires inside my tires. I have tryed all the kinds of tire liners before giving up and using old tires. I ran those tire to death because I could not see what was making the bumps (covered with mud for months on end). I finally put more air in the front tire, but got more bumping, so I finally had to check them. Had to wash them to see what was happening. could have gone another month, but the tires were about to start another hole.

"tires are heavy, around 1,100 gr" that is not heavy! heavy tires do not slow you down unless you're drag-racing from stop light to stop light. it is a myth! heavy tires can only serve to give you more more momentum for the up swing on the next hill.

I would use solid tires if I could find any that are strong enough. One kind I saw was as soft on the surface as inside the foam. If I were rich I would start a company for very heavy duty bicycle equipment.

The bicycle industry does not cater to utility cyclists, this needs to change. I hate the bike racing industry for destroying the durability of all things bicycle. I really should just build a cargo motor cycle and motorize it. I have done so much research that I could do it if I just had enough money.

"scintillated" is a term used in describing the disc brake pads with grit.

Leebo

20" on all wheels? Much better choices for 26" wheels. Pic of bike? So what exact tires did you use? There are like 50 different kinds of marathon tires. You might be maxing out the weight limit for 20 " tires. Check out Universal Cycles, BSD tires. Seems like some beefy BMX tires, 2.2 and 2.4 widths.

LesterOfPuppets

The tires in the first post look like they were skidded. Are they both rear? 26"? You'll have to replace often if skidding often. You can try using more front brake (if equipped) to reduce skidding.

I'd keep running liners, I like Mr Tuffy regular, not the lite.

As for tires, For rear you can get Michelin Country Rock for $10 occasionally, for front you can find Kenda K193 for $10 sometimes. Five of those would outlast 1 $50 Schwalbe.

LesterOfPuppets

Actually, Maxxis Hookworm front and rear, if frame has clearance in back.

canklecat

Yeah, that would limit your choices.

Most of the Michelin all purpose tires are rated for 36-87 psi, based on rider weight, etc. - higher pressure recommended for heavier riders/loads. But I don't think they make any of the Protek series for 20x2.

I'd prefer heavy duty tires with the puncture resistant liner built into the tire. More likely to be better balanced and integrated for long wear and reliability.

Sounds like you have unusually demanding riding conditions for a utility bike. I'm wondering whether the added tire liners might have contributed to the unusual wear patterns in your tires. Perhaps a slight bulge in the added liners may have contributed to the wear?

I noticed the additional weight, compared with my original Specialized Hemispheres, only for the first few rides after switching to the Michelins. Even then I noticed it only on uphill climbs. I use this bike mostly for errands and recreational rides up to 20 miles in a day, so the little extra weight is no big deal to me. And the additional puncture resistance and excellent grip on all surfaces offsets any weight.

Not much incentive in the US. Many folks live in areas where public transportation isn't practical: not enough population density, long distances between destinations, cheap gasoline. Some states and metropolitan areas could make it practical but the incentives are too tied-in with federal government subsidies.

I've noticed the bicycling industry does respond to conditions, but these are usually linked to short term trends in the economy and fuel prices. For example there was an interesting burst of specialization and innovation around the mid-2000s. This seemed to coincide with the overall economic collapse. There were some interesting bikes aimed at encouraging casual cyclists to ride bikes for errands, short commutes, moderate exercise, etc. Globe offered several interesting bikes. The Shimano Coasting automatic shifting system seemed appealing for folks in relatively flat areas. Seemed like an ideal time to promote more affordable e-bikes and trikes as well.

But as soon as the economy recovered a bit and fuel prices dropped, the incentives were gone for developing those types of bikes. That's always going to be the challenge with leaving transportation issues to shifting political whim, rather than making it part of a long term strategy that's primarily driven by civil service planners, designers and engineers who outlast elected administrations.

jawnn

sounds like you're trying to invent a reason that it is my fault. the inner tires have no effect on the outer tires. those Odyssey bmx tires do not have anything but foam under the tread.

jawnn

the tires were not skidded. that is what happens to a tire that has no rubber under the tread. BMX tires are not made for asphalt.
20 front 24 rear. the rear is still doing fine because they are bigger, less were.

jawnn

Every time I have looked for moped tires, I found only bicycle tires.

But now I finally read the right article; they are made so much stronger than I ever thought: , 16 X 2.50-inch 22-inch O.D. diameter [rated for 62mph] would use a 409mm rim?. I hope they are at least ¼ to ½ inch thick rubber.

4 ply rubber but at 35psi? I need at least 65 psi.

How ever it may need a wider front axle??? I have a $95 1.25” wide Odyssey 409mm rim built onto a disc-hub with 100mm wide axle. (too bad Sun Bicycle co. stopped making the “BFR” rims, they were almost half the price)

I may have to build a new front fork with disc brake. I was going to buy a fork for recumbent bikes, the only “disc” fork that is not over one hundred dollars.

But the old BMX fork I have on this bike now is way too hard to add a Disc brake tab to. Maybe if I use square tubing it would not be so hard to build a new fork with tab. I would need a tutorial for that.

So the question is: Are there any ready made “disc brake” forks for 2.5” tires? I also need the steer tube to be 1 inch. Maybe “trials bike” forks? Over 2.5” and I will not be able to use my finder.

LesterOfPuppets

Maxxis hookworm comes in 24" also. I'd probably run those.

LesterOfPuppets

I see Sunlight recumbent fork for $60. Looks like 1" threadless steerer. I dunno if steerer is long enough for you.

CliffordK

I have been looking at the Tannus SOLID tires.
Tannus Tires - Solid Bicycle Tires
Musai Aither 1.1 Road Bike Tires

I have a set of 700c x 25mm tires ready to mount, but I haven't gotten them mounted yet. Soon.

There are quite a few other models for many different bikes. Once I get the winter commuter configured, I'll consider a pair for my bike trailer. I haven't had many problems with the trailer, but it is just a matter of time before I'm stuck.

Anyway, they should take any amount of abuse one throws at them (other than riding forever).

jawnn

people are still living in denial of global industrial heating and its effects. the world is about to change in a very depressing way. I don't think that most people will even survive.

jawnn

I have one on order, but I have used them before and don't think they are any thing special.

LesterOfPuppets

They have an exceptionally thick tread that runs well up the sidewall. They also weigh a ton, but if you're considering moped tires and solid tires, it doesn't seem like you're concerned about weight much.

It should outlast that alphabite clone in the first pic by many miles. Interesting pic, that - I can't imagine how that wear pattern could've occurred without skidding.

jawnn

there are two hole on that tire and a third was opening soon, holes allowed the inner tire to bulge through at 75psi.

I have legs of steel, thighs of iron. not dissimilar to these, but hairy men's

LesterOfPuppets

The wear just screams skid patch. Down past the threads in that area, but it looks like at least half of tread depth remains to the left.

Those alphabite clones wear fast but usually wear somewhat evenly all the way around
