TB Owners, what PSI?

[Sin City Trail Boss]

What tire pressure you guys running at? I know my door jam says 41 cold, but at that PSI it's a little too bumpy for my taste and get too much feedback on my steering wheel.

 

I set them down to 37-38 cold, but not sure if this may be too low?

 

For those that have the 18" wheels with Duratracs, what PSI you running?

 

Thanks

43 all the way around. Sweet spot for me!

Cold or hot?

42-43 cold

[lebag335]

Cold. On 100 degree days the heat ups them to 45. Works great for my ride comfort!

32 in the Goodyear  18" tires..  40 psi is for the 20" eco tires,  too damn harsh

Also 18” w/ DT tires here. Agree on 41 not being comfy. I’m running 38 now and it seems a little better but haven’t tried going lower. Will try 32 but wouldn’t that wear the tires out a lot faster and noticeably worse MPG??

Btw - the door sticker assumes you’re fully loaded so that’s usually too high in real life anyway...

That's what I was thinking too! I wanted to go down to 35 psi, but scared it may be too low considering truck calls for 41. 

 

Hopefully someone who know tires can chime in.

once they warm up on the road they end up at 35-37psi

I cruise around with my front tires at 38 to 39 and rears at 35.

So I ended up staying at 37 cold and the ride is perfect now. I just hope they're not too low and get bad wear in the future. 

 

I will keep an eye out for wear patterns.

I have an RST that had the 20" but I just bought some Trail Boss take offs that are being put on today. When I get it back I will be chalk testing the tires to see how low I can go and still get even tread wear. I'll update everyone after.
