My 28" marathon pluses are 740g each. Good for training!

The day they make a flat proof 160g tyre will be a great day!

you're a beast! any flats?

I meant elimante flats

well it seems im going to be using mr tuffys.
does anyone know the deal with them causing flats which Ive heard happens.

Super flat resistant tires feel just as, if not more, 'dead' than tire liners. That's the tradeoff.... good performance & light weight Vs. puncture resistance. I've never heard of liners, Mr. Tuffy's or others, causing flats. And if they ever have, I'd probably attribute it more to user error than the liner itself.

true that ^^^^ well thanks all you guys I try the liners first and hopefully save my self $90

Good plan. Also, as suggested, check your tires for embedded road debris after each ride. I think if you do the Mr Tuffy liners and check tires for debris (and remove any embedded glass/shards), you will be as close as possible to having no flats.

People say they chaffe the tube. I've never had that but could see the possibility in very low pressure applications.

If you cut to fit, make sure you soften the cut edge by sanding it. I can't stand running with overlap above 100 psi, I can totally feel the lump.

im 120lb, thanks for the tip but i dont get it

i tried the slime tubes, they're great for spewing green **** everywhere when you get a flat.

I thought Slime was OK in my MTB tubes back in the day. Seems like the worst idea ever for road tires. Can it even keep a small hole shut @ 80 psi, much less 100+ ??

i've got a suggestion, i just did a "find" (in this thread) on "stan" and "slime" a came up with only one reference to "stan" that was not germain so i guess nobody has recommended using them for this.

i've never used either of them myself and i don't know whether or not they can even be used on normal tires. i suspect they can. but if i was as adamant as the OP about not getting a flat. i'd just get a one of those belted_guaranteed_not_to_flat tires that may flat and add a tire_liner_thats_guaranteed_againt_flatting that occasionally flats anyway, and bottle or can or whatever of stans or slime or maybe even both that guarantees_your_tire_wont_flat and probably still does, and throw it all in there...

edit: i have to edit this because on the second page there are a couple of discouraging references to slime tubes. so i'd get slime tubes anyway (as i say IF i was as adamant as the OP in his opening salvo concerning flats.) and start from there.

so that's one slime tube, nestled inside one tire liner, make that two tire liners, all wrapped up in a belted armadillo_horseshoe_crab_rhinoceros_skin tire. ya, that should work!

I know one data point doesn't prove anything conclusively, but the only time I ever saw Slime was when it started oozing out of my friend's 700x32 tyre on his touring bike when he got a puncture. About all it did was make an oily job slimy as well as oily.

Slime is iffy on 29er MTB tubes-- my father in law tried it and the slime worked a few times, but then eventually failed. (Theory: perhaps all the slime blew out, considering people running proper tubeless do add sealant periodically.)

Slime definitely won't work at road bike pressures. I have no freaking clue why they sell slime road tubes.

They also sell slime liners. They seem to work well, but they're a lot heavier than Mr Tuffys. I also have experience with the Panaracer kevlar fabric liners. Not too great... they won't stop a goathead.

Sheeesh. Another thread about "flat-proof" tires and nobody mentions TPI count.

OP, there's no such thing as "impossible" to puncture. They're rubber after all and not adamantium. Look at tires with a low TPI, eg. 60 TPI or 120 TPI. Not 300 TPI race tires. And read Sheldon Brown's write up: https://sheldonbrown.com/tires.html

Incorrect.
