Guys with 37s on stock rims with a diesel

[6006spd]

So what are you guys running for air pressure in the tires on and off road? I just put my eav 2 inch spacer kit on and am in the process of picking some rubber out, looking at Firestone mt2 37x12.50x17 for my stock rims for now any pictures or info would be great

late af response. But i run 25 psi on my 37s for on road. 8-12 psi offroad. im using 37s on stock sport rims as well.

Yup I settled at 32 for the pavement seems ok

I am running 34 cold on mine on road, 12 off-road. I have the Milestar Patagonia M/T-02s and was told by a factory rep that they are designed to have a crown on the tire. That being said, the pressure depends on what tire you are running. I generally run through some water on the driveway and then see what the footprint looks like on the pavement.

Another fighting factor with the factory wheels and a 12.5 tire, is that the tire is going to want to naturally put a crown to its wear pattern… dropping the pressure for a chalk test is going to be a fine line between good contact pattern on road and heat development.

Ran factory narrow wheels on a couple sets of 37x12.5’s before finally picking up a set of wheels- poor man’s bead locks. you should be able to drop tire pressures pretty low off road without de-beading.

I don't recall seeing a tire manufacturer recommend 12.50 on a wheel narrower than either 8 or 8.5 " . Sure you can go narrower but their is a reason the manufacturer has wheel widths stated . Many do use a 7.5 as I did on the road for a week , is it right , no. Not to mention side walls look funny. Off-road do as ya want at low air pressure

I have 37's on the Rubi rims. Pressure set at 28. I'm getting center tread wear. If I set it lower. I start to get a wobble in the steering. Saving up for new wider rims.
