slightly stiffer, but I love how it rides now. no body roll and a more sporty feel.

I have them aired to 50 PSI (max of 80 PSI) ... so they are definitely stiffer than P-rated tires at 35 PSI ... but not at all "uncomfortable". It rides more like a truck, yes ... but it's still very smooth and responsive, and actually handles better (not as mushy).

I'd make this trade every day of the week considering I'm not riding around delivering fragile merchandise.
