Greatings to you all.
I have 175-65-14 Toyo 800 Ultra tires, what would be the ideal pressure for rough roads, i mean very bad, bad roads, Montreal Asphalt sucks...
My current 44 front and 40 rear is good on nice pavement but maybe to high for bad roads, it's killing my back.
My tire "specialist" suggest 35/32 because bigger tire needs less air!
What are your suggestions....

With those larger tires you could run as low as 32/30 COLD pressure for comfort. But for added safety 35/32 would be a good pressure for what you want. Try it.
Next time you may consider wider tires like 185/60R14 or 195/55R14 for added comfort and safety.

You could also try installing a spacer to increase the effective travel of your rear suspension, and use a slim lumbar support cushion for your back. I used to live in Montreal. I suspect that the salt in winter has something to do with the road conditions.

How big of a spacer and were do you install it.

As of lumbar support, i have installed a ajustable Schukra lumbar support,
make a big improvement on those seat. The installation looks like the seat came with it as O.E. Very easy to install. You can check it at http://www.schukra.net/products/model_q_big.htm
cheap to...

Guillermo, 35/32 seems to do the job fine, i will play with the pressures to find what suit me. Deffinitly the next set will be larger.
