Yea definitely, the tire size ends up being about 34” tall and 11.6” wide. I did a full NorCal mod and the rubbing is now gone.

1.5” lift in the front. Still has a slight rake, not completely level, but I like it. Running a 275/70r18 no rub full lock. Don’t judge my crooked bumper. I still haven’t got the hit and run damage fixed. :(

Nice look!  I'm considering 285/70/17 LT's on my truck with a 1.5 level/lift.  I am adding a leaf to my rear springs and installing 1.5" spacers to the front to maintain a stock profile.  I am "beefing" up my truck for a major road trip with our travel trailer.  Did you find the larger, heavier tires to have a significant impact on your mpg's?  I could go with 265's but for a few $ more I can get the larger tires.

Thanks! I have a running spreadsheet for mpg documentation. The numbers did drop, but I have not reprogrammed the ECM or BCM for the change in tire size (looking for advise to get this accomplished), and I have not put a formula in the spreadsheet to correct the value. I’ve had that on my to-do list so I hope to have an accurate answer soon. Something I noticed is that the transmission seems to be confused by the new tire size. I don’t really know how to explain it. It gets about 13mpg when the cruise is set anywhere from 65-69. If I set the cruise on 64 or 71-72 the mileage seems to go up to 17-22.

1.5” motofab block in the front. 

 

Thinking about Nitto Grappler 33/11.5/20  for tires.

I have the same year and same truck. I have the motofab 1.5 up front as well, and have been researching coopers new line of at3’s for new rubber. You have the setup I’m going for. Any way you can grab pictures straight on of the truck to show the width of your tires? Maybe turn your wheel as if your turning left?

im going back and forth with 275/65/18 and 285/65/18, but now you got me going on 275/70/18 due to no rubbing and I can actually see someone with the same exact everything as I have. 

I like the sidewall of the xlt’s better than the lt’s But it’s not a deal breaker, the tire size is going to dictate it.

thanks!

From my calculated/corrected odometer numbers I think my math is still buggy, but going off of the trip meter readings at every full-up, it looks like my average MPG went from 17.55 to 16.15. I expected it to be worse!

 

I'm going off of this guy's formula. Again, I think something isn't right, but I can't get my head around it.

I took a few photos today and tried to grab as many relevant measurements as possible. It was easier for me to upload everything to my blog to keep from getting the thread off topic. Head over to https://roodeebee.blogspot.com/2019/02/silverado-ride-height.html for details. You might be able to go 1" larger diameter than the 275/70r18, but that would probably be pushing it. On my next set I'm probably going to look at going a bit wider just for a tougher look. The next size up in the Cooper AT3 XLT is LT305/65R18. I recommend looking at https://tiresize.com/calculator/ and clicking the "tire comparison" tab. Also go to http://us.coopertire.com/tires/discoverer-at3-xlt.aspx and click "full specs" for all sizes of that model. Good luck.

    • It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.
    • It was never mandated.  Ever.    Automakers were incentivized to install it by getting CAFE credits to help with their vehicle fleet fuel economy scores.  They were being handed money/CAFE credits to install it.  Which is NOT a mandate.       The current admin removed the incentives that were behind them installing it.       
    • Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!
    • If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.
    • My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.
