Simple question but the answer is probably not the same for everyone. What I do know is that in single player you can set the tyre wear to your choice: Off, Normal (1x), 2x, 3x, 4x, 5x, 6x, 7x. In multi player tyre wear is server controlled obviously.
choose a series with hard tires as an option. You'll suffer a little in pace, but the tires should last. As you improve, you can then try mediums before graduating to softs. Remember, low tire pressures usually work for a few laps, but we are beginning to see under-inflated tires suffering after only a few laps.
