This is my first time to try to install tubulars. I put two coats of glue on tire and rim waiting 24 hours in-between for drying. Then I put a third layer on the rim and let dry for 15 minutes, than installed the tire. The problem was when I went to straighten the tire (which I tried immediately after installing) there was no moving it! I tried till I had blisters, but just wouldn't do. The glue worked too well!! Question: Was 15 minutes on the last coat too long before installing the tire?? Not long enough??? Any ideas where I went wrong? Thanks for your input.

Could be you need to wait a little longer. I know Lennard Zinn recommends 15 minutes, but I fine 30 minutes works fine, keeps the tire (& me) from getting all gummied up, and allows me to easily center the tire.

You may also have put on way too much rim cement with each application. Also, I found Zinn's specs make the tire almost inseparable from the rim, so I've scaled back to one application of cement on the rim and the tire, and then a second application on the rim before mounting the tubular 1/2 hour later.

BTW, use a nylon tire iron to get under the tubular if you need to pry it off the rim. Good luck.

Tubbies

make sure the tire is stretched out adequately prior to mounting. In extra clincher wheel will do...mount the tire and inflate to around 100psi and leave for >12 hours.

I was worried about my tire coming off in a turn...until I tried to take one off due to a faulty valve. Holy cow! I had a hard time...complete w/ blisters

For years, I used to mount them immediately (like Spunout) after applying the final thin coat, then changed to mounting them when the final coat was just beginning to get tacky, usually in 1-2 minutes after application. Either way, it gave me plenty of time to center the tires. I think 15 minutes of wait time is too long—the glue is almost dry and will act like a good contact cement with that immediate and irrevocable bond.
