Ekdog, might I suggest simply ignoring CB Hi's posts. He is just trying to get a rise out of you.

... and among all the pointless bickering about glass and plastic, since broken glass on roads is a problem in the here and now (and probably will be for some time to come), you get to choose between (a) trying to avoid it, (b) fixing lots of punctures, or (c) using puncture resistant tyres to minimise the time and effort required to do (a) and (b) ...

ignored

For my daily commute over glass filled roads here on Guam, I run a 25mm Marathon Plus in the front and a regular 25mm Marathon in the rear with a 23mm Ultra Gatorskin inside used as a liner. I cut the bead off the Gatorskin and fit it inside the Marathon.

I carry no pump and extra tubes. I do not get flats regardless of what I run over. Bullet proof protection.

I agree with the good tires = less worry about flats. I have been running the bontrager hard case puncture resistant tires that came stock on my bike for roughly 3000 miles now and not a single flat to date. I have a section of my commute that I ride straight shoulder for aproximately a mile and there is always... tons of debree in my way. When I get home the first thing I always do is inspect each tire and pick out all the junk that gets stuck on the way. So far I have pulled out bits of wire, glass, plastic (car reflector shards etc) and what appeared to be a bit of bone off a dead pigeon. The tires are pretty eatin up but they are still going strong.

Great! No more broken beer bottles. People also wave hello to each other now and cars move to the side of their lane in order to let us cyclists pass.

3000 miles and your tyres are "pretty eaten up"? I've got over 3000 miles on my Marathon Plus tyres and I recently looked at a new tyre to see whether mine were showing any wear at all. It turned out the tread is a little less deep than a new tyre after all.

All I do is ride them, if I happen to notice something sticking out of the tyre I'll remove it but otherwise I just keep turning the pedals.

Kentucky - It is because they are drinking moonshine out of plastic milk jugs, rather than beer out of bottles?

I'm driving to work tomorrow. There is one particularly bad stretch where the remains of two or three bottles are scattered on the shoulder bike lane along a 100 meter stretch. I'm bringing a broom. I'll sweep it up. I'm tired of either running over or dodging the glass.

I second that. I don't even bother to inspect my Marathons and Guam's roads are 3rd world at best. Just install and ride and forget about carrying pumps and tubes--totally unnecessary. I ride on and off road too--it simply doesn't matter with these tires.

I wouldn't go that far. I did have a single flat when a hawthorn spike pierced my Marathon Plus tyre, and despite being in one of the wealthier suburbs of London at the time it appeared there wasn't a bike shop for some distance.

I guess on my MTB the puncture protection is thicker still as the tyres are wider, and I've never had a flat through the Marathon Plus ATB tyres, or indeed through thge Marathon Extreme I put on the back.

I believe the probability of puncturing a Marathon Plus is low enough to ride without pump and tubes. I commute only 14 miles each way to work and always carry a cell so in the extremely rare event of a a flat I would just limp on the rim the remaining distance/walk or hitchhike. I don't like carrying extra junk--that's just me.

But yeah, if I were to venture out very far from home I would be equipped to handle a flat.

Moonshine?! This is Bourbon country... you need to lay off of that Maui wow-wee (which kinda explains that whole Spam mania down there).

and that comes in oak barrels...

What is Maui wow-wee, something you eat with your moonshine?

No Kentucky moonshine? Right.

Glad you regard me is such high esteem to consider me on the same level as the Dalai Lama.

+1 mount the new tires yourself. Here's another tip I recently saw. When you mount tires, put the middle of the tire logo even with the stem. Then, when (if) you inflate the punctured tube to find the leak, you will know where to look on the tire to find the breach and be able to remove the shard of glass or sliver of metal or thorn or whatever. If you don't remove whatever caused the flat, a new tube won't last long.

+1 ... well, "calling the hubby"

It happens that is a Marathon plus + a tyre liner

+ plus 1 for changing you Tyre at home your self before you go out, saves your self a lot of trouble when you know exactly what you are doing.
