What psi?

Boden08

Hi,
I've Armadillo 700x28c tyres on my commuter bike (Specialised Sirrus Elite), and am wondering what pressure should be maintained for regular road conditions. The tyres suggest 75/100psi, but that's quite a spread...would welcome input (excuse the pun!),
Thanks,
B

Don't use those tyre myself but I alway put the pressure in my tyres to a minimum of 100psi - so I say do the same: you'll be much more efficient on the road than if going at the lower end of pressures and you'd have less a chance of getting pinch flats

@CheGuedara- I am presuming you are running 700x23c tyres which is quite narrower? Different widths need different pressures.

Anywhere in the range will be fine but I would probably go 90 back/80 front on 700x28. Sheldon reckons 100 back/80 front but he also suggests 120/100 for 700x23 which I think is a bit extreme in the rear (I run them at 110/100.)

@ Blorg - oh cr@p, yeah, mid evening dyslexia there - swear I saw a x23 not x28! :eek:

@ Boden08 - +1 on what Blorg said, a bit back off the max and those wider tyres would be grand for commuting on

Thanks Folks,
I'd had 80 on each, but will go with Blorg's suggestion on 80/90.
Appreciate the tips,
B
