These are great tires for the money

Best tire for the money, but us old Schwinn freaks really have no other choice. As far as mounting goes, you need to put a thin layer of dish soap on the bead before you air up. I have also used WD-40. You will see the bead slowly pop into place at about 60-70 PSI. Make sure the rim line is visible, & you will have a smooth ride.

Kenda S-6

I put these tires on an older model Schwinn Speedster made in April 1975. A little work and they were on with no bulges and ride smooth.

Great price and perfect fit

I ordered these for my 1977 Schwinn Breeze. I did a good bit of research before the purchase. I called and spoke with customer service and he did try to point me to another tire that would not have fit. I checked again and decided to go with these tires. They were perfect. My vintage bike is like brand new.

Fits Schwin S-6 as advertised

Restoring an old Schwinn Breeze (1968) and tires fit the S-6 rims just fine. Seating on the rim not as easy as newer rims. We'll see how they hold up.

This was the only viable viable replacement tires I found at a reasonable price for old Schwinn rims.

As mentioned these were the only viable replacement tires I found for my old Schwinn Collegiate with 26 x 1 38 tires on Schwinn rims. The tires I replaced were gum walls which I would like to have retained. The black walls are O.K. byt I would have preferred the gum walls. They (Kendas) fit but were difficult to mount on rims in even manner. I had to massage each several time all around to allow mount to rims with even sidewalls no high and low areas causing lumps when rotated. If such uneven mount transpired on a motor vehicle the inbalance would cause the complete inability to control the vehicle and the ride motions would be nauseating.

I bought these for my 1970's 26 bike.

They were slightly too big for the rims. So I couldn't use them.

Hard to seat evenly so the tire runs true but it's the only tire left for our old Schwinns.

The problem with these Chinese Schwinn-sized tires is that it is extremely difficult to seat them on the rims so they will run true. There is always one area of the tire that sits low or high on the rim causing a thumping ride. With a number of tries, inflating and deflating and pulling on them, it's possible to make them tolerably round but far from perfect. If I wasn't appreciative that Schwinn-sized tires were still made, I'd rate them lower, but they're better than nothing.

best tire for the money

I HAVE A COLLECTION OF SCHWINN BIKE BUILT IN CHICAGO IL. THESE TIRES AND TUBES ARE AS GOOD AS THE ONE'S THAT COME WITH THE BIKE WHEN IT WAS NEW. THE PRICE IS GOOD AND SHIPMENT IS HERE AT MY HOUSE IN 5 DAYS. WHEN I ORDER FROM MY SCHWINN STORE IT TAKES LONGER THAN THAT AN THE PRICE IS HIGHER AND A HOUR DRIVE TO PICK THEM UP.

My first experience with BTD and it was a snap. Liked the products and you can't beat the prices. Whether you are a weekend rider or a serious enthusiast, BTD fits the bill.

Great tires for S-6 rims!!!

Had to replace the tires on my 1970 Schwinn Racer..43 years old and are still spinning, but needed new rubbers. These fit perfect on S-6 rims. Be patient and seat them correctly!!

Just what you need if you are fixing a 60's era Chicago Schwinn cruiser.

If you are working on an old Schwinn with the hash marks between the spokes this is what you need.

Great tire for the price, you have no other choice

I put these tires on my 35yr. Schwinn Speedster & Breeze about 4 yrs. ago. I have 1,000 miles on the Speedster & I'm sure they will be good for another 1,000. The Breeze does not get used much & the sidewalls are starting to crack a bit. Great tire!!!

Affordable, sustainable, perfect fit and easy installation tire for your lasting, old schwinn!

This is the only place I found a tire that fits my old Breeze Schwinn perfectly and easily installs! Very affordable price and strong for the road an great speed! I use it every day back and forth from work. Excellent. I wasted money and time and effort on getting other 26 tires that say they fit all sizes. Not true! Finally found the one that fits and lasts, and sustainable on bumpy roads, even grass and gravel. Thanks!
