All depends. There will be more drag from the extra rubber, or you're probably giving it more welly to use the tyres. Most likely, although I cannot be bothered to work it out - you will have changed your rolling radius, therefore gearing and most likely read less miles than you did before. Others may like to correct me, but seems plausible to me.
