FWIW, mounting Conti's on my William's 30's the first time is always a finger buster. Once they loosen up, no problem.

Once the tire was ridden in and taken on and off a couple time, it has stretched enough, though it still needs a bit of effort. FWIW, I use Velocity's Veloplugs instead of rim tape, so I have a little wiggle room.

Makes sense but I do have older Deep Vs on our bikes made in Australia. I don't remember having any issues but I'll take notes next time I swap tires for a new one.

Maybe I'll make a video of the swap

I have ridden with another forum member that uses them. He's had nothing but good luck with them. Maybe he'll get the flat!

thanks, Beanz. Some of my riding partners have been telling me that I've become a big *****. Your video will show the world that they're right.

What kind of mileage are you guys getting out of these tires on the rear? I've got maybe 1200 miles on one now and it's showing wear down the center, you can feel it starting to get that flat strip. Still, I've had zero flats while riding on some pretty awful roads, so they are durable. IME, once I start getting punctures repeatedly, it usually means the tire is worn.

The GP4000s has wear indicators. Once these dots are no longer visible it's time to replace them.

I just had my first flat on my GP4000S yesterday, and it was a DOOZY! More of a blowout really, right in the center of the tread area. The slice in the tube is about a quarter inch long! There is an accompanying slice in the center of the tire now too and I'm debating what to do with it. I've only got 450 miles on that puppy so I really want to keep using it... I may stick one of those park emergency boots in there (currently has a spare bit of innertube).

I had roughly two hours to squeeze in a ride yesterday and my wife said "Don't go too far because you get flats n stuff"

She cursed me, clearly. I didn't even know that was still possible.

Thanks for the wear indicator tip, I didn't know what they were for either.

I'm amazed at how many riders don't know about the wear indicators.

But then again, I know riders that don't know about the little direction arrows either.

One guy recently had his tires flowing the wrong direction opposite the pattern. I mentioned it and he argued till I pointed out the little arrows.

BTW, some rims also have wear indicators on the brake surface.

I pre-stretch mine. I posted this in another thread:

My method requires some pre-planning, but it's very effective:

Woodworking clamps.


I do woodworking as a hobby and have several parallel clamps, as above. The "jaw" with the wooden handle can be removed and reversed. With the jaw reversed, the clamp is now a "spreader"- or in this application, a "stretcher".

I can fit 2 clinchers on 1 clamp and I try to get the process started a day in advance, maybe 2 days, if it's cold out. I don't have a pic handy, but I also made a pair of half-circle spreading cauls to place over the clamp's contact points i.e. the round part rests against the clincher. Using the cauls eliminates any potentially damaging stress, caused by the square edges of the clamp.

This process has worked for me and my friends'/family's tire & rim combos each time, every time. Gatorskins on an ultra-stiff, deep rim or Hutchinson tubeless on Shimano wheels? No problem. No levers required.

Just don't overdo it with the stretching force. As always, YMMV. I do have a Kool Stop Bead Jack- just in case, though.

Sometime ago I read one poster just layed them out in the sun to heat up which relaxed them. Sounds easy enough and the sun is free.

If nothing else they tell you when the rubber is getting thin in the center of the tire. That is usually a precursor to frequent flats.

As far as wear down the center of the rear tire I'm pretty sure all Continental tires square off in that area.

I actually did that once (didn't want to throw a tire in to the dryer, as some do). Laid out a new GP4000 on my parents' driveway. I never got a chance to see how effective it was because a stray dog picked it up and took off. Besides, the sun is only available for half the day.

By the way, the newish GP4000S on my rear wheel doesn't have wear indicators. I've only got maybe 450 miles on it too, so it's definitely not worn down.

I've had about 6 pairs and never seen one without wear indicators.

They are very accurate for telling you when the mfgr wants you to buy a new one.

Very strange, I have newish 4000S and used on the bikes. On the bike have 1 indicator alone with 2 others in another spot. 3 of the new tires have 2 in one spot and the 4th tire only has one indicator in one spot.

Maybe it's a stamp type production step like metals. They stamp every so often along the strip. Then sooner or later, things get mixed up down the line somewhere then 1 part ends up missing the stamp.

Seems you got the one bad apple of the bunch!

Nope, I found 'em. What's the point of only having one or two of those things/ If you can't see them the tire's worn out?

That cut I put in the tread area is bulging... I may end up chucking the tire. Sad.

I'm not sure what it was... but I distinctly recall thinking "I should steer around that thing" POP!

I walked back looking for it to save some other poor soul but no luck.
