I think they say about a tenth for every 100lbs? though I dont think thats 100% accurate.
I spreadsheet all my runs and have my PB's at full weight with the stock 275's up front and in very similar DA (though I always run a lithium battery which only weighs 5lbs) vs pulling the seats, trunk weight etc. I have never run smaller tires up front though will probably give them a try at some point.
