I've been given my dad's old 70's bike to restore. It's a 10 speed Lambert Aerospace ( http://www.sheldonbrown.com/lambert.html) and it would look a lot better with some skin wall tyres like the originals, which have now deteriorated.
Trouble is, I can't find too many! Any ideas?
Don't know about puncture proof but I've been very impressed with my Vittoria Corsa G+ over the past 7 months. Just one puncture in that time despite riding on some pretty poorly maintained surfaces on a regular basis and I'm putting that one down to running slightly too low pressure/not checking before the ride. Mine are 25's but you can get 28's.
Panaracer Pasela
Corsa G+ have been ok so far no punctures as of yet fitted at Xmas
I'd go with 25c Corsa G+, as they come up pretty wide.
It's an obvious point, but are the wheels 700c or 27"?
ah! You're right, they are 27". Existing tyres say 28-630.
Damn all these wheel sizes.
Pasela is available in 27 x 1 1/4 if it'll fit.
I'd second the panracers, Run them on an old tandem. Depending on brakes, you can swap wheel sizes, but 27" will be the cheapest option
