Tyre pressure advice

Currently at tyre shop Mounting a set of 305/55/20 mickey thomson mtz on 20x10 wheels. Bought over the web. Guys at shop have no clue what air pressure to put in the tires. Any thoughts from someone with similar setup?

 

It doesn't say it on the tires?

 

40PSI to start.. go from there

 

tires only list the max recommended for that tire. The pressure to in depends on load. People that run the pressure on the side wall of the tire will have over filled tires 100% of the time.

 

 

Go with what techrep suggested (40 psi). You'll be good with that.

 

40 it is. Thanks to all.

41 is the correct pressure.

Just kidding, it's preference. You'll get better gas mileage the higher pressure you go. Personally, I like between 40-45...my buddy runs 60 all year round.

 

Looks good!

 

Looks great! I like mine at 45. Good economy, nice and nimble, not too firm.
