tire suggestion for trek fx 7.3

hi. i bought a trek fx 7.3 a week ago. i appreciate the bike very much. but i have a small problem. when i ride in roads with paving stones(concrete pavers) i feel a lot of vibration from the ground. so i slow down. there isn't bike paths and pavement isn't in a good condition most of the time.

what do you suggest to reduce the vibration and to ride more comfortably in these bumpy roads. original tires are 700x32c bontrager race tires. if i buy a 700x32c tire set should i ride more comfortably? or the overall performance of the bike fall when i use a more wider tire set. any suggestions.. thanks

Read this:

You have only a few tyre choices for your rigid fork bike; a little less pressure in the existing tyres, or fatter/taller tyres with more air volume, but less pressure in them, if your forks and frame clearance will take them.

A 'trekking' type tyre might help but everything is a compromise between speed, weight, acceleration, puncture avoidance, and rolling resistance. Choose any two.

I have Continental Contact Sports on my similar bike, the ride is bearable, fast enough, and not too harsh. I run at 65 PSI.

Others fit Cyclocross tyres, or heavier 'touring' tyres like Schwalbe Marathons.

I really like my Schwalbe Marathon Supremes. A set of 35s should fit in there. Actually, I run a mixture of a 40 on the rear, and a 35 on th front of my Crosstrail.

They "vibrate" a little bit when new, until you get the edges worn smooth - but they have been flawless in performance. I run mine at 90-92 PSI, for a really super roll, without sacrificing comfort.

I have the plain old Marathons on my 20" folder - a pothole magnet if ever there was one. They're extremely good on London roads. :-)

Have you considered keeping the stock tires and using a suspension seatpost?

It might not sound as a simple solution, but it will definately help to make your ride more comfy: get a suspension fork!
For tyres I use the 35c schwalbe CX comp ... they are quite cheap yet durable and versatile.

thank you. you assisted me a lot. should i use all kind of all kind of 35c cyclocross tires.

http://www.schwalbetires.com/bike_tires/cyclocross

and i had a look at this tire. and i recognized that suggested air pressure is 35-65 psi

http://www.schwalbetires.com/node/1337

as i know suggested air pressure for tires start from 75 psi. according to trek's web site. or does it use a different measurement unit? so i am a little confused

what kind of suspension seatpost should i consider. bontrager nebula plus or anything else

Those stock tires are quite rough riding. I have them on mine too.

Some people have suggested the Panaracer Pasela Tourguard as a suitable replacement that is more comfortable. I'm considering these myself when I replace mine.
