Cheng-Shin?

My 1981 Miyata 1000 has Cheng-Shin tires in 27 x 1.25 and when I looked at Maxxis to see what Cheng-Shin had in terms of road slicks, I noted the rubber I have is no longer available... should I keep them on or upgrade to something more modern?

I am going to restore and paint with some flavor added in - looking at some flake and shimmer and metallics for the decals - should I keep the original rubber in this case?

Opinions will be listened to.

(Cheng-shins are cheap)nvm. But anyways, just because they don't have that tire, doesn't mean that you should keep those on there just to have the same brand name, any 27X1 1/4" tire will work on it.

Is Cheng-Shin really that bad? If so, what would a good recommendation be for 20-mile daily commutes? Obviously my n00b roots are showing...

Cheng-Shin isn't that bad. There are worse bike tires.

Just don't buy their car tires.....unless you're into drifting.

With a 20 mile commute (round trip I hope) you will be looking for new tires pretty quick anyway. If you really want to keep the Cheng Shins I would take them off and store them and put a good quality kevlar belted tire on for the commuting.

I'd just ride the Cheng-Shins until they give you problems or wear down. Or, now that this thread is rattling around in your head, check this thread out in the commuting forum. It includes some of the top recommendations for tough commuting tires.

By the way, Cheng-Shin manufactures tires for many brands, and they aren't all crap.

A word of caution: your first mistake was asking! The 'upgrade sirens' lurk everywhere on bikeforums!

Although we aren't nearly as bad in C & V as in the Road Cycling forum .

I had Cheng Shins on one of the bikes, which eventually got replaced with similar generic tyres of the appropriate size. They aren't anything special.

I did want to mention that I enjoyed your blog so far .

Ha! The posters here are merely the roadies of 30 years ago. Vintage Campy, Dura-Ace and Suberbe Pro ain't cheap!

Okay, I'll concede, C&V is much more diverse than a bunch of retrogrouch former racers, and posters here are far more skilled at sustaining topical discussions than some other forums. But there's also an ample dose of VOCP (Vintage Obsessive Compulsive Poseur) snobbery.

I appreciate the blog endorsement - I'm glad people like it. If they don't, oh well. I just wanted to know because another bike commuter at a school I work at asked me if I worried that the rubber would split, being so old... so I'd thought I'd ask.

Well, I will keep thinking on this, and blogging on it. Thanks for your input.

Any tire will work. I have bought some *Mart tires and the border between the sidewalls and tread wasn't very straight, so it looked funky, but they worked fine.

There are still reasonable quality tires available depending on your needs. I just bought some Panaracer Pasela TG tires that look like they will do what I need admirably.

If you want gumwall / tan sidewall, they seem to require a little more hunting than for a pure black tire, but they do exist. I have some 1 & 1/8 Continentals (I forget the model) with a classic look waiting for the day I want a narrower tire.

+1 on the Panaracer Pasela's. Hard wearing and great vintage looks. I have used both the standard wire bead and the folding, belted TG's. If your bike has a hooked bead rim that will take higher tire pressure, they will perform well.

I didn't realize they were the original tires. It is a good idea to inspect them closely. Do you see any tread separation or dry rot?

Personally, despite my previous posts , I'd equip it with new tires if I were commuting 100 miles a week. If they were new Cheng-Shins, I might consider running with them for awhile.

Bontrager Sports at your Trek dealer, and maybe other places. Roadwinner II's are another nice tire. I actually like Serfas Seca's, although someone will come along saying they're crap, lol. They ride smooth, and have flat protection though no skinwalls.,,,,BD

Well, I did check them out - in fact, my bike is up on my stand (I'm so proud of myself, I made one from an Instructible) and I was looking at them, especially where the rubber meets gumwall, to check for cracks and separation. Nothing so far. I check my tires every couple of days, just to be safe. Vintage stuff means more careful maintenance.

Any bike needs this, but especially a commuter which will see lots of miles. If you haven't already done so, a few inexpensive items to replace/repair will ensure safety and optimal performance:

Replace brake pads if they are hard, cracked or give poor braking performance.
Replace cables and housing (or clean and regrease) if you experience poor braking and shifting performance.
Regrease and replace bearing balls (25 grade or better) on bottom bracket, hubs, headset, and pedals.
Regrease stem and seatpost to prevent seizing.
Lubricate all mechanical pivot points (on derailleurs, brakes calipers, chain)
Degrease any heavily gummed up parts on the drivetrain.

As a commuter, knowing how to perform these services will save you money and will be helpful in the event of a needed roadside repair. Although there's an initial learning curve, they are all relatively simple tasks.

Of course, you may know all this, seeing as how you already have a work stand!

Cheng Shin are fine tires....I know a Dutch couple who toured on some Chengs (not exclusively of course) and had nothing but good things to say for such an affordable tire...

I was puttering in my shop this morning...I have 3 bikes with Cheng Shins on them. Two were OEM; a touring bike and an MTB. The MTB tires are over due for replacement and are dry rotted. The other set is on my beater Raleigh as replacement tires. FWIW the touring tires look brand new and have reflective sidewalls and that bike dates from around 1990 or so, hasn't seen too many miles

I've had excellent service from Wal Mart 27" X 1 1/4" tires. Good for smooth dirt roads too. Here's a pic of the tread and my very Fred anti-flat device.

In my neck of the woods, that tire is a Bell brand, "Streetster"?? You used to be able to buy them in gumwall with a full reflective strip, then they went cheapy blackwall with a one half tire relfector. Unfortunately what used to be a good looking tire is now ugly. I imagine they still perform well. Use a thorn proof tube or a tire liner though.,,,,BD

Here's the gumwall/reflectors on my P8. I no longer have the bike. I made it a single speed and it went to a charity auction.

Yep, I've run across that before. At the Honda shop we flat out will not sell them to anyone with a bike of over 500cc. And happily, very few customers will even ask.

Actually, one of my motorcycles has Cheng Shin's on them as we speak: My 1969 Honda Super 90. If you've got a small Japanese bike from the 60's, they're about the only alternative out there. And they work very well in that application, just as they do on bicycles.

Guess the secret to Cheng Shin's is to not use them on any vehicle that can do over 45mph.
