Im running 285 70 17 Goodyear Duratracs on my 07 silverado. Iv been running them at 60 psi but I have been told to run them somewhere around 40psi. Im really annoying of my indicator inside saying my tires have to much air because they are set for the factory tires at 35 psi. I mostly drive e-way. and through downtown. I dont do much wheelin. If anyone could help me out, that would be great. Thaknks

If thats the pressure your going to use then have your dealer reprogram the TPMS to that pressure.I had to have mine done beacuse the 35's I have run 65psi.

For a truck our size recommended PSI is anywhere around 35-45 PSI.

 

For Jeeps and compact trucks its 30-40 PSI.

 

For 3/4 ton trucks you run higher PSI like 60-75 PSI along with load range E tires. Depends on towing.

well I want to run my psi at whatever the recommended pressure is. If 40 psi is what I should run them at, then i shouldn't have to go to the dealer to reset them. It seems like its more of a preference as long as im under 65psi. But id like to know what pressure to run them for better gas mileage and what will help the wear of the tread.

I don't know what the recommended psi for that tire is. But I'm pretty sure the tighter the psi the better the gas mileage. Higher psi does make the ride more uncomfortable though. You might try 40-45 psi. I can't be tight enough to hurt them I don't think and it should be tight enough for best fuel mileage.

How do you like those tires btw? I'm thinking about getting some.

I absolutly love the tires. Very quite and handle great on the e-way. Iv done a little wheelin and noticed a big differance compared to the stock tires. They even hook up alot better on the snow coverd roads, which ruins some of the fun of doin donuts and whatnot but are definitly easier to handle. all around great tire, and i have about 8000 miles on them, no sign of ware

If they are load range C then max pressure is 50psi cold. Load range E can go up to 80psi. If you have E I would put em around 50 unloaded for a good balance on economy and wear.

I run 35-40 in my load range E, 285 70's. I had the dealer reset the "magic number" to 40 psi, so I can bump them up to 50 when towing without the sensors freaking out. There is no need to run 60 psi in an empty 1500. Your gas mileage wont be any better then 40 psi, but the ride will be much more harsh.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.

      There's some truth to the above, but also, she's selling fullsize trucks and bread/butter CUV's like hotcakes, meanwhile, extracting GM's pickups from the deep discounting sales game.   GM's stock has held its own during her tenure, and the more recent buybacks are delivering cash back to investors and signal confidence in their direction forward. Even with the EV losses.   GM is an example of a modern publicly traded company. The #1 goal of any publicly traded company is to deliver the most value possible to shareholders. Despite being a car company, building the best car isn't GM's path to delivering maximum shareholder value.   McDonalds doesn't make the best burger, or the best coffee.   I've mentioned in another thread, I really don't / won't ever understand Cadillac or Buick in a modern context. Both brands are completely dead to me. I'll cede that the Escalade is a nice SUV, but the brand and nameplate mean nothing to me, and GM will never persuade me to pay north of $170k for a gussied-up Tahoe or Burb. Other people don't mind doing that and that's their purview.   The C8 shares absolutely nothing in common with any other current Chevrolet or Corvette on the market. Since its introduction 8 years ago, it's developed quite the following. It did what other Corvettes couldn't do: reduce the average age of its buyer. GM has something there, and I see them investing in the car. They'd better not mess that up.   We've successfully derailed Grumpy's thread again, but I think this one is meant to be more of a random thought thread so a little wandering is probably OK.

      Sliding doors ftw   Also, Sienna ftw as well.  The in-laws got a 2024-2025 recently when their 2019 sienna was totaled due to a deer back in June.  They've been getting 38-40mpg on the 65mph highway they live on.

      Forgot to mention that this started after changing the oil I use mobile 1 full syn with mobile one filter but I did add pro lube additive and was the first time doing so and is making me wonder just can't see why that would matter
