reTyre: they’re tyres that zip into place!

New design is intended to offer a quick solution for changing conditions

Startup brand reTyre is offering tyres that can be adapted for different surfaces and conditions with the addition of a surface “skin” that zips into place.

Well, it’s certainly an interesting idea.

“After thee years of development, we at reTyre are now ready to launch the world's first modular tyre system where you can change the surface of your tyre in seconds using integrated zippers – adapting the bike to your needs,” says reTyre. 

“We have built our own factory and ensured international patents to be able to disrupt the tyre industry and improve the riding experience of all the fantastic year-round bikers out there.”

“What we hope to do is to make biking easier and better, reduce the unsustainable rubber consumption of the tyre industry, and challenge what a tyre can (and should) do.”

Okay, so here’s the concept: you have base reTyres tyres on your bike and you can zip what they’re calling skins over the top to suit the riding you want to do.

One half of the zip sits permanently on the base tyre, just above the top of the wheel’s rim wall, the other half of the zip lives on the skin. You put them together, zip ’em up and away you go. You don’t need to deflate the base tyre to instal the skin.

The zipper is said to be ‘highly durable’ – you’d hope it would be – with the same lifetime expectancy as the tyre, and it’s self locking.

Obvious question: what’s the point?

“Correct treading provides better grip, less rolling resistance and a better biking experience,” says reTyre. “The tyres also last longer.”

The idea is that you can quickly attach a new skin to adapt to the weather and/or road conditions without the need to fit an entirely different tyre. The skins are also said to provide addition flat protection.

reTyre initially offers off-road skins and studded skins for winter riding. 

“We are launching skins with embedded electronics and LEDs using inductive charging and communicating to your smartphone,” says reTyre. “We are also introducing new exotic materials such as textiles, recycled coconut fibres and completely recyclable skins.”

The base tyre is ERTRO 42-622 (28-1.60) size – 700 x 42 – with a 26in version planned. The skin increases the size, obviously, normally up to about a 47mm width, according to reTyre. It isn’t tubeless ready although a tubeless version is in the works too.

We’ve not used reTyres so we can’t tell you whether there’s any sort of bump when the join in the skin touches the ground. 

The base tyres have RRPs of US$35.99 (standard type) and US$69.99 (premium type). The off-road skin is US$54.99 while the urban winter skin – with 156 studs – is US$69.99.

reTyre will be available soon to pre-order on www.retyre.no and Kickstarter.

 Zip them on in a matter of seconds, right after you’ve spent 20 minutes picking the mud and horse shite out of the zip teeth

Not if you buy my soon to be marketed new essential cycle too with a zip cleaner, just trying to calculate how much I can charge for them.

Studded tyres have been around for ages and are cheap as chips - I purchased a set of 35mm Schwalbe Winters for £20 each this winter.  Rode a 70km fast road ride on them just fine.

 I could see myself swapping these twice a year - October and March (I live in Scotland). That's about 10 minutes of DIY, or if I *really* couldn't be ased, probably £20 at an LBS. 

Let's be charitable and say the cost of the basic base tyre and the studded skin is £80. The cost of a decent studded tyre is £20, a decent city tyre maybe £30. so £50 a pair, per wheel. Let's say we're at break-even. 

Which leaves you with the risk of the zip-ons failing - catching a sidewall on a kerb or rock, clogging up with road filth and salt, etc, along with being way heavier /larger than the alternatives. And you have to do the unzipping/on-zipping, assuming that all goes well after 6 months of non-use/use. 

Sorry to be a downer on someone's dreams, but I just cannot see this flying. Happy to be proved wrong.

That's between $212 and $280 for two tyres and urban skins.  Struggling to see why you wouldn't just buy another wheelset if you genuinely need to swap between studs and studless on a daily basis. I bet swapping out wheels takes less time than faffing about with (rusty?) zips.

Sometimes innovation comes along and changes the world. Sometimes it can offer a small improvement in a niche area. Sometimes the innovative part is convincing people that there is a problem at all. Then there are ideas like this.

Well I can do that with any Hutchinson tire and some Gorilla glue, see after about 800 to 1000 miles the center smooth part of the tire begins to peel off away from the cornering tread, much like a retread truck tire you see blown off on highways, so all Hutchinson would have to do is to make different types of center treads  and produce a glue that would allow easier pulling off and we could simply pull off the one and glue on the other...

They taking the effing piss with this! The amount of time you would lose fitting them and the garbage ride adding yet more rotating weight for conditions that are more likely to be slower/stop-start riding would more than be vastly more by using a not quite perfect tyre for the conditions.

Utterly bonkers!

Unless your tyre is really stiff from too much rubber/thick puncture strip/poor carcuss, so as these will fit into at least two of those categories in a major way (at least when the outer tread is zipped on), the rolling resistance will be way higher and completely negate any benefit provided by the tread pattern.

Strikes me that these guys are coming at a problem from the wrong angle, but have no choice as if it was just another 'normal' all round tyre the product would likely go completely un-noticed and will probably be out performed by the existing offerings.

I think I'll stick with stuff from other manufacturers that offer good all round tyres thanks to well designed tread patterns and quality construction (schwalbe G-ones, Panaracer Gravel King SKs, etc).

Good luck to them though as I can see these would be great for city bikes where a quick switch to winter condition tyres would be made very easy and do-able by people not up to other bike maintenance.
