What pressure did you end up sticking to? I ask because I recently purchased the same tire size and load rating (275/65/r18 116, Duratracs funny enough - I wanted to stay away from the LT versions too) and have been trying to nail down the best pressure. Usually just stick to 35 but I’ve noticed my fuel economy has been pretty bad at that pressure.
I do find it interesting that they spec’d those 265/65 duratracs so high even though the load capacity for that size and load rating (114SL) caps at 36 psi. Wonder if it’s something specific to those duratracs, softer sidewalls perhaps.
Makes sense. I have not had them long enough to see how they wear, but I did confirm elsewhere that the stock 265/65/18 Duratracs on the midnight editions do in fact call for 38 psi in lieu of the 35 psi for the regular all season tires. Must be for better wear if the engineers spec’d the stock Duratracs out for 38 psi from the factory. Thanks.
Hello, I recently purchased metric 275/65/R18 116SL (Not LT’s) duratracs. Truck was born with P265/65/r18 at 35 PSI. Shop set my new tires at 38 psi which seems kind of stiff for a Non-LT tire. For those of you with P rated duratracs (or 116SL rated tires in general), what pressures have you been running? Using this website (https://tiresize.com/pressure-calculator/) it’s saying that I should run 32 psi (!) to match the OEM spec for load capacity and tire wear. 32 psi seems way too low, even if it can support the same load. I read on here that the midnight edition 1500’s recommend 38 psi in their factory P265/65/R18’s duratracs. Can anyone confirm this? If this is what I’m supposed to run in mine then so be it. I called multiple shops and got multiple different answers but none below 35.
Makes sense. Did you ever end up getting the +1 offset wheels on your truck? And did it stop the rubbing? I’m actually looking into new wheels and I want to get a 0 offset (+1 mm is basically 0). Just wanna confirm it helped before I pull the trigger. Personally I am more of a fan of the “flush” look which is why I’m aiming for 0.
Yea I agree. They actually don’t look bad on the truck as is. I was surprised to learn they were +30mm. Feels like I don’t see that high of a positive offset offered on new 18” wheels, so I guess it’s uncommon.
Makes sense. I strongly feel that these tires were already rubbing the control arms at stock height. Sucks that new wheels are so much money. I’ll probably get a 0 offset wheel down the road. Just to confirm, the +1 offset now clears the control arms, correct?
2018 crew cab Silverado z71 275/65/r18 (32”) Rockstar 2 +30mm offset Bilstein [email protected] 2” Leveled using bilstein 5100 at top setting. Using readylift UCA to help with ball joint angles. Noticed that the readylift sticker has rubbed off on one side. Below shows how close the control arms are to the tire. They are rubbing while in motion at full lock based on the marks I can see on the arms. Do I have to get wheel spacers or is this not much of a concern? I know +30mm is pretty tucked in, not sure why the previous owner chose these. They could’ve been rubbing at the stock height too, I just never noticed until now. I would prefer not to use wheel spacers so if it’s nothing serious I won’t bother. I don’t even feel or notice it while driving or parking.
