reinforcing tire against punctures
hi, I've been to the bike shop today and inquired about that kevlar strip that is inserted between the tube and tire to reinforce it against punctures, well they didnt have that particular thing but they had some piece of hard rubber that suppose to do the same trick and then they went ahead and fixed it in the tire for me (for some added funds) , is it a common practice? since its just rubber and not kevlar is it going to give me any extra protection? cheers

My whole bike is overkill and heavy as hell so a few more ounces doesn't matter much. Weight matter less to me than comfort and reliability. I'm not ridding to win a race but going from A to B without any trouble. My bike chain weight 17lbs, 2 rim tapes + 2 liners per wheel with the M+. One protection for the rim one for the tire. I have noticed at least 30% less rolling resistance since i changed my tires from the studded kenda klondike tires to the M+. I'm now flying because my legs was used to carrying this weight. And yes i was riding all year long with studded tires. I already had a flat with the kenda tires from a spoke going through a rim tape due to the heavy stuff i was carrying so i sandwiched a liner between 2 rim tapes and haven't had a flat since from the inside. I also got a flat with liners, the hole was exactly at the edge of the liner so i went for M+ tires

Why would you ride with studded tires all year?

I live in Canada half of the year is ice and snow, the kenda klondike tires have the advantage that i can ride with them on both icy roads and dry roads and are very good on wet roads as well. But those tires should be avoided when there are debris on the road because studs get in and puncture happens

FYI, being a heavy rider at 220 lbs I tried the Mr Tuffy strips (rubber), they actually did more damage than good. The overlapping edge eventually saws its way through the inner tube and cause a flat. I tired placing tape over the junction, filing down, trimming and whatever else i could think of and eventually it cuts through the tube. I have a ride buddy far less in weight ( 150 lbs) that has no problem.
I can't get more than 200 miles with a rubber type tuffy liner before it cuts my tube.
My best advice is use good tires and avoid weight weenie tubes.

Those rubber tire liners were on the market waaay before the kevlar strip liners.

A review:
Weaknesses: Consistently caused flats for me and my riding partner approx every 1000 miles. Solution was to place duct tape over the Mr Tuffy overlap
A second review
Bottom Line:
Didn't provide any additional protection and may have even "cut" into the tube on two different times. Finally removed them from by tires.
===============================
AND from the mr tuffy site itself
Q I’ve read in some forums that Mr. Tuffy will wear a hole in my tube where it overlaps. Is that true?
A We’ve read that as well, and there is some evidence that it’s possible. In the early days, Mr. Tuffy tire liners were trimmed by hand. Once the volume of sales was measured in millions rather than hundreds, we had a special precision cutting machine developed that uniformly trims the liners to the exact size and shape needed for maximum effectiveness. It is unlikely that the overlap causes flats using the current Mr. Tuffy product............. I myself tried Tuffys in 1997 with the liner cutting my tube on my tandem. Then I tried them again in 2005 on my single bike, with the same results.
A Dealers have told us that they grind or file down Mr. Tuffy’s end edges and they apply talc to the inside of the tire before installation. This advice seems to make this particular problem disappear.

Another alternative is to use Slime Tube Sealant (aka "goop"). It gets great reviews on amazon, and my friend swears by it.

Slime tire liners consistently got bad reviews, but they've introduced a new and improved version. Anyone familiar with these?

Surely, you don't have a chain that weighs 17lbs, unless you say chain meaning some sort of mega security device.

20mm thick sounds pretty secure, alrighty.
