2010 Jeep Wrangler Unlimited tire pressure light still on

I had 2 new tires put on and my tire pressure light is still on. The other 2 tires are also new and we’re put on 6 mths ago. Is it true that I need to drive it 80km before the light goes off.

No , that is wrong. Do you have the proper pressure ? Have you looked in the manual for TPMS reset instructions ? It may be that the tire shop may have to reset for you.

New tires or old will make no difference, if the warning light is on there is a problem. Check the pressure in all five tires, after inflating the tires the warning light should turn off after a few minutes in most cases however this is what the owners manual shows;

The system will automatically
update and the “Tire Pressure Monitoring
Telltale Light” will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (25 km/h) to
receive this information.

If the warning light is still on there may be failing tire pressure sensors, on a 9 year old vehicle that is not unusual. You will need a shop with equipment that can connect to the TPMS and check for failing sensors.
