Hello,

I'm planning on buying road tires for my mountain bike and was wondering what would be the better option, as far as rolling resistance/speed is concerned.

One tire is 26" x 1.25, is 410gr and can be pumped up to 65 psi, the other tire is 26" x1.4, is 405gr and can be pumped up to 85 psi.

Any suggestions on what would be the better tire?

Thanks.
