Those of you running 275/55/20 tires, what pressures are you running for normal everyday driving? Just had KO2s put on and trying to get close without doing a lot of testing if everyone is close to the same pressures.

 

I still run 44 front and 50 rear. I know a lot of owners run the lower range and say the ride is better but I don't feel that I need a better ride than I get with 44 and 50.
I don't have enough miles on my Yokohamas yet to see if they are wearing more in the center or edges but I do measure it each rotation and will use that measurement to make an adjustment to tire pressures if needed.

 

I thought the 44/50 the shop put in our Yokos was a bit much. Have a TON of those road seams around these parts. Ba-Bonk Ba-Bonk. 40/46 is better for us here anyway. Still hear them. Just don't feel them as much.

 

I have Fallen AT3 in that size and I run 46/40. The 50 PSI is at the upper limit for the Falken and the ride is really harsh

 

Hoping to resurrect this question.

I'm about to put on some KO2's in 275/55/20 on new rims. I typically run the lower (recommended) pressure, 34/37, for everyday driving, and up it to 44/50 if we go somewhere with a heavy load. This summer I'm towing a trailer up the east coast and wondering if 44/50 is enough on KO2's? Do you guys run the lower (recommended) pressure when your payload is lighter?

Also, did any of you have alignment done when you changed the wheels/tires? I currently run 22 inch (with Pirelli Verde All Season) so I'm reducing the the rims size but I think the diameter/circumference is roughly the same.

 

I have the OEM tires (255/55 R20), but have always wondered why such a high pressure is needed in the rear tires. I usually keep it at 44, as 50 sounds excessive and does impact ride. Any thoughts?

 

50 is for carrying 7 people or some other heavy load.
Way too high if lightly loaded and absolutely impacts ride quality. I set mine to 39 in the summer which is a touch on the high side but means they will still be above the recommended pressure on cold nights.
