Thinking of getting some Duratracs 34.5 to replace my 37" iRoks for Winter. Also pretty tired of the rough ride. Wonder how this will look with a 4.5" lift.

 

Well, as for the tire and the ride, I can say they're great and you'll really like them. I can't attest to how they will look with 4.5" of lift, but this how my 315/70/R17 Duratracs look with 3 1/2" of lift. Oh, and mounted at 33 psi, they only end up sitting 33 3/4" tall.

 

Being on the moon not too many people will notice that your rig resembles a roller skate, but it should perform pretty well.

 

Yours looks great! Why on 33 though??

 

Lol... tons of things happen on the moon. Just can't figure out which way to go. Tired of my loud, bumpy 37" iRoks.

 

After a chalk test for this specific tire and playing around with different psi over 6 months, I find 33-35 psi the best for overall ride and mpg. At 35 - 37 psi, I get a bit better mpg, but the ride becomes a bit more rough around town. Just personal preference.

 

Yeah my duratracs stand 33 and 3/8 for the 315/75r16. They are a great tire and ride great. I lowered my psi to 30 but I guess I should raise it to 35 or a bit more to improve my mileage.
You will just have a ton of room to flex.
