How noticable is tire weight?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

How noticable is tire weight?

I just went from 300 gram 700x25 gatorskins to 350 gram 700x28 Bontrager Race Lite Hardcases.

The Gatorskins will be my summer tires now. But in the meantime, I'm just curious if 50 grams per tire is enough for actually feel when riding. It seems harder to get up to speed, but I've also not been riding as much as usual.

Other than the weight, how are the Hardcases holding up? I was thinking of getting a 700x32 for my cross/utility bike to see if maybe they might handle better than my Armadillos and still have the puncture protection

I suspect that the increase in diameter has more effect on spin up than the weight.

I went from 25mm Bontrager Race Lites to 23mm Conti GP 4 Seasons. The Contis seem to role a bit easier. The bigger difference is that the Conti tread has been much more resistant to wear.

Since they're still practically new, I should hope they're holding up fine. The ride is smooth and they seem pretty grippy but I haven't pushed them either.

I doubt you'd notice 50gm, maybe 100gm if you've got super lightweight wheels. And even then, only in cases where you're doing maximum accelerations all the time. Like tight crits that require constant braking and acceleration out of the every corner. Then yes, you might be able to notice a 100gm difference. But it's very, very small...

You might notice 50 grams per tire when you try to sprint, but you won't see much speed difference in a 25 mile time trial.

Note that the new folding Gatorskin tires are 230 grams (700x23).

I change from Armadillos to Bontrager Race X-lite. I noticed the reduced rolling resistance (rubber compound) which gave an increased cruising speed. The only difference I noticed due to the weight was in lighter steering.

I'd think that would feel like moving from Minneapolis to Houston.

Some people notice small changes some people don't. A good friend of mine had his old steel wheel Varsity changed to aluminum rims(a big change), and lighter tires, he could not notice the difference. I can tell the difference between a pair of 240 gram tires vs. a pair of 260 gram tires, on a light bike. Mainly when accelerating from a stop. It also has to be one ride right after another for me to tell. If I wait a day or two I can't tell on a change that small. It depends on the bike too, some make it more noticeable or less noticeable.

The only thing I noticed after switching to Armadillos is that I don't get flats anymore.
