should heavier people use higher pressure tires?

i keep mine at about 115 to 120, which is close to the max, but was thinking about switching to tires/tubes with recommended pressures of 145. I thought maybe being 200 lbs with higher pressure would be better. any thoughts?

It would depend on your riding. 145 PSI is a great pressure for a race tire on a smooth surface, but as a road tire? For a Clyde? I suspect it will beat you to death!

What are you currently running for a tire (Size, brand)?

Well, if you can afford to experiment, go for it then. If you like a hard ride, the higher pressure tires may be your cup of tea then.

I ran my race tires at 170 on my XXX lites.

Tubular FTW?


It's not uncommon for tubulars to go to well over 200 psi. So if you can afford it, definetly worth it in my opinion. And they ride SO SO much better.

Tire pressure in clinchers should be kept high enough that you will not suffer a pinch flat when you hit a bump or small hole. As Clydes that means we generally need to run higher pressures than those thin as twigs riders.

On my clinchers I usually run about 140 rear/130 front, on my regular ride (tubulars) I do not need to run pressure that high and generally run about 10psi less per tire.

You should be running bigger tires, not higher pressures. The standard 23mm tires are made for standard 150-pound riders. Most of us posting in the Clyde thread should be on 28s at least, bigger if they'll fit (they won't on most bikes). I weigh 230, and I do most of my riding on 35s at about 80psi. I'm not any slower than I used to be on 25s at 115, and I'm a LOT more comfortable. I have 27mm Rivendell Ruffy Tuffys on my Rambouillet (it came with them), and they're really good tires, but when they wear out I'm going up a size on that, too.
Grant Petersen at Rivendell has a guide to tire sizes and pressures based on rider weight. Check it out:

Note his claim that you won't go slower on a big tire if your weight calls for it. It's been 100 percent accurate for me.

I've been running 23mm width tires at 100-110 psi for years with zero pinch flats. I'm 205.

For me, 105 front/110 rear is as firm as I go, beyond that the ride is too harsh.

Hi,
I am trying to get Schwalbe to make a Marathon Supreme in a 32c.
I've emailed them and mentioned it when I ordered the tires i am using this year (Racers, actual size 28c).

Here's the tire if you want to see why I am hot to get one in a middle size...

toothpick? toothpick?? I'm not gonna pay $$$ for a tire that was tested using a toothpick. Sorry.

higher pressure or higher volume

I'm usually ok at 120 psi.

I ride Tufo tubular-clinchers at 130psi. I've got 4 road bikes that I ride regularly and have the same tires on each bike. Probably have around 2500 miles total and zero flats this year.

I've got a question: Can I run different width tires on a 700c wheel on front/rear? say, 28mm front/35mm rear

In the past, I've done it with 26" offroad tires.
