Even different tires of the same model will compress more on the front of our SVXi than the rear due to front weight bias.

I measure the distance from the topmost edge of the rim to the ground and adjust the air pressure (within manufacturers specs) to match that measurement with the tires cold. Then I'll take a run to warm them up and tweak a little as needed.

It's a good point you make Dan, softer sidewalls might make the wheel sit lower in the tyre.

That's very thorough, your matching the rolling radius like that. I only ever keep the tyres at the correct pressures or maybe a pound or two higher all round for comfort.

Full marks!
