Strengthening Road Bike Tires for Puncture Protection

AI Thread Summary
Using a hard or rigid Kevlar layer in road bike tires could enhance puncture protection but would increase tire stiffness, potentially reducing rolling friction. However, this increased rigidity may lead to a harsher ride and greater vibration transmission, especially on uneven surfaces. While it could help maintain tube pressure better, the trade-off might be a loss of traction due to decreased tire deformation. The discussion highlights the balance between puncture resistance and ride comfort. Overall, careful consideration is needed when modifying tire construction for performance benefits.

On standard road bike tires sometimes they put a soft/flexible kevlar layer to protect against puncture.
I was thinking about putting in in hard/rigid kevlar layer to also protect against puncture, I know that this will make the actual tire stiffer and harder to deform, which could be a bonus to lessen the rolling friction (loss of traction though)
also I thought it would lessen the dramatic decrease in tube pressure after riding.
all thoughts or comments appreciated

I imagine it would also make for a much harsher ride especially over bumpy surfaces. Even over not so bumpy surfaces, you'd probably get more vibration transmitted through to the rider.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
