Bought GT Hybred w/ 700D+extra tires @LBS
 
My Dad retired a few years ago, then wet macular degeneration took most of his vision. Dad has always enjoyed riding so he has invested in a tandem so he can continue to ride. I found it at a local bike shop at what I thought was a very reasonable price for a CRMO frame. I checked the internet about the GT Hybreds and found many coments warning me NOT TO BUY IT DUE TO 700D tires. The LBS had extra sets of tires so I bought two extra sets and asked the owner if he could order more? he said it should not be a problem.
My question is should I buy up the 3 other sets he has on his tire rack Or is he correct ordering new tires will not be a problem.

The bad news: http://sheldonbrown.com/harris/tires/587.html

I don't know where your bike shop got all of those 700D tires. Are you sure that's what they are?

In any case, rather than buy all of those tires, I'd use what you have until they wear out. Then, if you're still riding it regularly rebuild the wheels with 650B rims. While they are not mass market items either, they have their adherents and several manufacturer commitments for continued supply.

They are 700Ds I checked them before closing the deal. I picked up the bike yesterday and asked again about the shops ablity to provide tires, the owner said he had plenty in stock in his three stores. I know that I saw two more sets on the tire rack.
Well I know that I have 3 sets so if any one is looking for 700D tires: Bike America in Overland Park Kansas has at lest 2 sets. The owner (Nick) said he has more at his other stores.

Those wheels/tires on the GT were a major drawback; jhat sizing never took hold. If you plan to hold on that tandem buy a few set of tires while they are still available . . . they are usually a very rare find.

Sourced from Bike America?
 
Interesting reading that people all over the world want this tyre size to fit their GT Continuum or similar ..
Interesting to read the reference that Bike America had plenty - a the time/day of the thread being posted.
Unfortunately Bike America have not replied nor acknowledged receipt of an email I sent them on January 16, 2011.
Pity - looks like my Continuum will be off to the recycle cyclery ...

Drop me an email if anyone knows where to really find two 700D x 1.4 with ISO 587mm tyres (and tubes - always handy to have)

cheers

Still looking for my tyres
 
Anyone found a stash of these tyres yet?? .. currently GT Crossover brand/type. Size is 700D x 1.4 with ISO of 587mm - fitted on Araya RM-20 rims 700D w tube liner. Two (or four) tyres (road tread pattern is fine) would be good and two spare tubes would help as well
My preference is to fit the right tyres and not change the wheels..

Preferences are all well and good; then reality sets in.

There are two choices from ETRTO 587: 584 or 590. Both offer a wide range of tires, for example Schwalbe has street 25-590 to 42-590, and wide selection of street and MTB in 584 sizes. For on-road use, the choice should be driven by which direction you can move the brake pads as much as anything else. In reality it is preference.

Keep the 587 wheels and tires for a future restoration project, get 584 or 590 to ride the bike now.

I had a Gt for two years and ran 650b tires with no problem. Used Vee Rubbers, Continental, and Pacenti.

Just been to a local bike shop to buy inner tubes for my upcoming 700D project. The technician said that 26x 1-3/8 should fit in the original GT tires.

Can anyone please confirm this ? I tried buying 27.5 inner tubes but the slimmest I found on the market was a 1.75.

ETRTO 590 (aka 650A, aka 26 x 1 3/8) inner tubes will fit fine, you are talking a 3mm diametrical (1.5mm radial) difference.

Thank you Nigel for the clarification and assurance.

Time to bite the bullet and build up a set of ISO584 (650b) or ISO590 (650a) wheels.
