Technically, the speed on the speedo will match the same rpm on the tach as before. But, your truck will be moving faster than what the speedo says you are going. If you want to figure out your speed, divide your new truck tire size by your old size and multiply that number by the speed on your speedo. that should give you close to what the new speed should be. Example: new tire=35, old tire=32; 35/32=1.09 ...now say your speed says 60mph... 60*1.09=65.4mph.
