Looks great. I was pming a member about these yesterday. Im still debating on either 285/65/18 or these 275/70/18's. Either way the truck looks great.

285 is a little shorter tire, supposed to be a little wider. however according to bfg's site the only place it is wider is the section width, not tread width. i liked that these were alot cheaper than the bfg 285($70/tire cheaper), and they are lighter by about 3 or 4 pounds each.

Hey, I just bought an 08 just like yours... Thinking about putting the RC leveling kit on. You have any problems with it? And also do these new BFG's rub? I've kinda been looking at the 275/65/18 s and the ones you bought... Still don't know which one to get yet. But your truck looks good!

they dont rub anymore. i dont think that they would have rubbed anyway, but they were on the driver's side, but the fender well came loose due to a high speed water entry(deep). i fixed it but only after it mashed the fender up good, so i think the plastic was warped. it doesnt rub anymore, i bent it in a little and presto...fixed. as for the 275/65-18, i looked at those as well, but i wanted a little lager tire. those measured out at about 31.75"(with a tape on site), and these were about 32.25". not alot of difference, and only like 2 pounds difference in weight. i like them alot, although i miss the capabilities of my mud tires, but not the noise!

I know you have a 2 inch leveling kit but, do you think the 275/70/18 would fit on a stock gmt900? On the discount tire direct website they list this size and the 285/65/18 as plus zero size tires for a gmt900 truck. I believe this means they will fit on a stock truck. I was just hoping for some verification before I bought them and them had to turn around and trim the fender or order a leveling kit.

Dmitri, I am sure that the 285-65/18 will fit on a stock suspension, as i have seen one on this setup with no problem. as far as the 275-70/18, yes i believe it will work for your stock truck suspension. if they scrubbed a little you could fix it relatively easily without a leveling kit if you wanted. you could simply bend the plastic a little so it would clear, or slight trimming with some tin snips. i have so much room i dont see how they could scrub on yours. i have seen a set of 315's(hummer take-offs) on a set of stock 17's on my brother's GMT900 GMC. now he does have a leveling kit, and they did scrub, but he could still drive it, just not turn the wheel full lock. hopefully that answers your question. personally i would put either a rough country kit on the truck regardless(you can adjust from 1.5" to 2"), as you will need an alignment anyway with the new tires(good excuse to put the leveling kit on).

How much do these 275/70s change your gas mileage from the stock tires? I put the 285/65/16s on My old truck ('98 sierra) and I got about 1 to 2 mpg less.

The + zero means on your oem size rims. If you look at the tire sizing, the + 1 will be 1" larger diameter rim.

Sorry, just checked back. I am getting about 25 or so miles less per tank than before with the stock tires. Those are P metric and alot lighter though. Love my tires, no probs with them rubbing. They will take some power ou of your bottom end too. They measure out at 32.25'' inches tall.

 

That would be about a 1 mpg loss of fuel economy by the way.

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      OCI, not when but why?

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
