Tyres

Hi All

Sorry if this has been covered a million times before. I'm currently running 700 x 23c tyres on my Moda Bolero. The state of my local roads is nothing short of shocking (aren't they all?). I was wondering if changing from the 23c's to 25's at slightly lower pressure would ease the severe vibration from the road? Currently the 23's are at 120 psi as recommended by my LBS but the vibration is enough to shake your fillings loose!
Any advise would be most welcome.

I don't think you would notice much difference between 25s and 23s, all things being equal . Others might disagree.

I run 23, 25 & 28c tyres, you can imagine the state of the roads down here! I find that the 28c's are much more comfortable on bad roads. The difference between 23 & 25c is negligable. If you have the clearance to fit 28's give them a try, you should find an appreciable increase in comfort. Try running them at around 90psi and see if that makes a difference. I can fit the 28's to my Dawes racer so you shouldn't find it a problem.

Try running 90 psi front and 100 psi on the rear. You may just keep your fillings

I bet the 120psi figure is because the tyre says 120psi max.
Its unbelievable how many folk think that's the correct pressure.
The pressure shoould be set according to type of tyre, road conditions and total weight on each tyre.
There are several sites that give a ball park figure.
Mine are set at 100 front and 110 rear atm.

With marathon 700x32c tyres which are specified for 60 to 100 psi I find best comfort is with 80 front 90 rear. Our road surfaces are dire, and last year I fitted a good suspension seatpost recommended by crankarm on this forum. Best component buy of the year.

Similar here - I have Marathon Supreme 32mm set at 90/100 and they iron out the dreadful lanes where I live very well.

The joys of being a noobie. I was under the impression that running them at a lower pressure could lead to a greater chance of punctures? I'm going out for a spin in a bit so I'll try 100/110 psi and see how I go. Thanks for the advice folks.

I run my 23's at around 85 front and 90 back. Much more comfortable than the 100+ I used to run, and I am yet to suffer a pinch flat from the lower pressures.

Yes and no at the same time- pressure is a fine balance of comfort vs drag (/speed) vs puncture resistance- therefore you can adjust it a bit and still keep the other two factors pretty high, it's finding the right balance is key.

Knocked out 10.5 miles tonight on the reduced pressures. What a difference! No noticeable affect on rolling resistance, but so much smoother ride. Can't thank you guys enough for the advice. Thoroughly enjoyed the ride and my enthusiasm is right back up there.
