Rim strength vs tire pressure question

My old Schwinn LeTank has been running for at least the last 20 years on the same set of tires,
and they have served me well. Now that I've been riding more (over the last two years), they have
finally reached the end of their useful life. They are Schwinn branded 27 by 1-1/4 tires rated at
85 psi, which is where I keep them.

The rims are steel and are in good condition, with only a very few tiny rust spots on the inner
surface (toward the hub). Am I likely to be safe putting some smaller, higher-pressure tires in
the 100 - 120 psi range on these rims to reduce my rolling resistance, or should I stick to the
larger 80 - 90 psi tires?

1. Make sure you have "normal" rims, not the Schwinn proprietary rim design that needs special
tires. Any LBS that used to have "Schwinn" in the name can tell.

2. In some cases, there can be problems with the tires failing to hold the rim, even if it's a
"normal" rim. I suffered from this on old steel rims even at 90 psi, and finally just pitched
them and got new aluminum rims. (They are a lot safer in the rain, as well.)

3. Can you even get 120 psi tires in a 27 inch size any more? What's available from whom?

Your options are limited. I'd suggest you check out the 622 conversion if that is possible with
your brakes.

That is new rims and spokes at a minimum, labor intensive.

On the other hand complete new wheels could be cheaper.

If it isn't then look at Conti TT2Ks in 27 inch as an option for new tires. Expensive but they will
last a while.

They won't be racing tires but they will be durable.

Steel rims aren't necessarily a problem except that they are heavy and they suck in wet conditions.
Many cyclists rode steel rims for many years, they aren't necessarily horrible but if you have the
option you should choose aluminum.

Or IRC Road Winner available in 27 x 1-1/8" or 27 x 1-1/4" for about $13. These are good tires and
will wear well.

They aren't dead yet, But it's coming fast for 27, you'd better buy up all those quality tires fast
before it all flakes out.

I've found plenty of 27-inch tires at Nashbar and other online catalogs, but they usually don't list
the pressure. Thanks for the suggestion about the Schwinn dealer; I've got one near me.

There will always be 27" tires available but they will be $5-10$ tires and you get what you pay for.

I saw some of these in a hardware/agricultural supply store not too long ago.

Shopping for the bent again, I see.

Anyway, while you were checking out the latest in
3/4 inch hose clamps and zinc coated lag screws with the other guys in cheap t-shirts and John Deere
baseball caps I was in shops like La Bicicletta and Campione talking Campy Record and with
Giuseppe and Paul wearing my cotton team Cantina / Tollo cycling cap and my nubuc -high NBS
vulcanized sole Oakley smoke amphibious breathable architecture sandals!

Now do you see the huge gulf between benters and elite level roadies like Me?

Yes, I see the difference. If you came around here dressed like that and started talking trash about
John Deere, you would get your butt kicked by the locals. 😉

By the way, us sophisticated 'benters' refer to them as Jubilee clips, not hose clamps. Such
ignorance.
