Changing a flat (Flo 30's)

Postby mrr11 » June 14th, 2014, 12:40 pm

I'm a year in to my Flo 30's and have been extremely pleased; however, there is one thing that is hard to do and that is change a flat. I'm using Conti 4000 GP tires and it is very hard to wrap the tire around the wheel. By far the most difficult tire change I've ever experienced. Even my LBS had a difficult time with these wheels.

Any tips or suggestions that might give me an easier time when changing a flat? Any tools that I might try?

Thanks!

I have the same situation...I've installed a set of Conti GP4000s II's, which were the most difficult to take on and off, and a set of Conti GP 4Season tires, which were only slightly easier to put on/take off. My tire tool would not grab the tires clincher bead when trying to remove the tires as they were too tight against the wheel rim. I had to resort to a blunted butter knife to pry under the tire bead just enough so I could slide the tire tool underneath and continue with a normal (albeit much more difficult than normal) tire removal process. When putting the tires on, I'd get to the point where my hands just couldn't push a the tire on the rim any farther. My tire tool is too thick so I resorted to the butter knife again. I would lift the tire bead about an inch away from the last tight contact point with the rim and slide into the rim...move an inch down and do it again. About 3 times with this motion snapped the tire firmly into place.

This is by no means my recommendation as there could be a myriad of problems arising from it...namely a puncture to the tube with the butter knife, or a bending of the rim if too much leverage force is used by the butter knife, etc. Additionally, I do never intend to carry a butter knife in my road repair kit, so in a mid-ride flat, I may have great difficulty. I'm searching for a set of tire tools that are perhaps metal and much thinner than the plastic ones I currently have.

My guess is the rim shape on the 30 is what's making these tires extremely difficult to put on and take off. I also am using the Zipp rim tape made for the firecrest shaped wheels. Mounting/removing tires on my Flo disc is bit easier using these same tire models.

Not sure this helps, but it is what I had to resort to in switching tires on my 30's.

I had similar difficulty trying to get GP4000s installed on my Flo 30s when they arrived. In fact, I ended up destroying 3 tubes and 2 tire levers before swallowing my pride and going to my LBS for a remedial lesson in tire installation. The mechanic there even had trouble but he was able to install the tire onto the rear rim completely by hand. He also passed on some tips (that I used successfully to install the tube/tire onto the the front rim.

Aside from the usual things (slightly inflating the tube so that it stays seated on the rim inside the tire, starting to seat the tire bead at the stem and working away, etc), the biggest two tricks he showed me were:

1. Brace the wheel against your pelvis, hold the wheel so that it is horizontal and use a rolling motion with your palms to roll the tire bead over the lip of the rim (this allows you to use more of your upper body for leverage).
2. When you reach the point where it seems like you won't be able to get the tire onto the rim, spritz the tire with a bit of Windex (or if you're on the side of the road, a bit of clean water works too). This adds just a touch of lubrication to the tire and makes it easier to slip over the rim. If you have a shop rag handy, you can place the rag over the tire for a bit of added grip.

Those two tips are what really helped me. I've even had to put it into practise on the side of the road when I flatted and was able to reinstall the tire fairly easily.

I just got my 30s in. I don't have much hand strength and was concerned about installing new GP4000s IIs. My history with Contis is they are really tough the first time and then stretch a bit. I put my new tires on my old rims and rode a couple of hundred miles, then put them on my Flos. While the Flos are a bit tougher it was no big deal, use good technique and they jump right on. I did use a tire tool for the last little bit but this is my normal technique.

Let's start with the basics. Are you using tire levers?

i did just received my new 30's and love them but it was quite a task to get the tires mounted. Ive done many others before as well but perhaps the wider shape we all love contributes to it. i do use 2 different type of tire levers longer and short ones as well. Maybe a vid with tips and tricks?? keep up the great work guys awesome products and even better fair value pricing.

JB,

We are actually shooting and editing a series of installation/maintenance videos this week. I hope to have them posted in the next few days.

Let me ask you this. When you get to the point where you need to use the tire lever, where are you placing the tire lever? In the middle of the excess tire OR at the edge?

Good question I've tried but right in the middle and to the sides. i did manage to pinch the tube on one of them with the tire lever middle section. I think it may be technique but done many others before. Glad you are doing additional vids that is great! thanks for your response.

I'd start on the edge of the access section - not the middle - and you'll need to make sure your tube is all of the way inside of the rim so you don't pinch the tube. We are still editing the videos but they should be up shortly.

Take care,

Like others, I had some difficulty mounting new tires - Conti 4000s II and Vitoria Open Corsa CX to my Flo 30. Now, after a short break-in period/stretching, I am now able to remove/mount both tires without any tools. The COnti is a bit more difficult - I suspect it stretches less the Vitoria.
