Title: 2004 Jeep TJ Sport - Recomended Tire Pressure 225/75/15
Post by: crusty on December 10, 2011, 05:24:05 PM

Hi Folks.
I bought this Jeep recently...spare tire and build sheet show 225/75/15 tires but placard on the door shows 215/75/15 with recommended pressure at 32 PSI. I'm thinking that it's the same for 225 and wondering if anyone can check their placard if they have 225/75/15 and see what that says.
Thanks a bunch.

Be careful, with a 10 mm tread width increase your whole drivetain could rip apart.

Having said that, I suggest 31.783 psi for the wider tires.

also 7.5 cm taller - the atmosphere is less dense at higher altitudes so may want to lower it a bit more, maybe 31.597
