Yes.  Sorry in advance, everyone.  From my research on this board, the topic has been thoroughly discussed.  Many times, however, specifics aren't discussed (e.g. "Wrapped with 35" Ridge Grapplers").

 

I'm about to take delivery of my AT4 and one of the first things on the list are new tires.  My plan is to go with a 35" tire on the factory "AT4" wheels.  Research shows that staying under 12.5" (the max that most shops will mount on factory wheels anyway?) will yield the best results in no rubbing.  I also would like to keep the tires from sticking out past the fenders.  So, I turned to Nitto's page to see what was available and surprisingly found 27 (!) 20" choices with several being roughly 35" in diameter.

 

Here are a the ones I believe I have narrowed down:

LT285/65R20 E 127/124Q ---- 34.8" Dia ---- 11.5 Wide

LT295/65R20 E 129/126Q ---- 35.12" Dia ---- 11.77 Wide

35x11.50R20LT E 124Q  ---- 34.76" Dia ---- 11.42 Wide

35x12.50R20LT F 125Q ---- 34.76" Dia ---- 12.5 Wide

 

Stocks are 275/65/R20 for reference.

 

My next stop is to call a tire shop and get their opinion.  However, I thought it would be good to hear the voices of people running these first.  Are these the four that people are generally running?  Are there others in the 35" territory?  Some of these are "LT" (light truck?) rated but have higher load capacities than the non LTs - further complicating this......

 

Thoughts?

GMC 2500 AT4 standard bed here - I have about 12k miles on Nitto Ridge Grappler 295/65/20 on Fuel wheels with a +20 offset.  Factory wheels are +44 offset.  My suspension is stock w/exception of Bilstein 5100 shocks which offer nothing for height.  I had very very slight contact on the front liners, which I pinned back with a zip tie on each side.

 

So, that means my wheels are 24mm pushed outwards, or 0.945".  On stock wheels, I don't think you'd have any rubbing at all.

 

I recently ordered a 3500 AT4 SRW standard bed truck.  I'll be running the same size on it too.  Along with +20 offset again.  I'll stick with it cause I know it works and it looks awesome too.

The 295 is roughly an inch wider.  Will they stick out on stock (+44) wheels?

 

 

Actually closer to 3/4" and that is only 3/8" on each side of the wheel.  You won't even notice the difference other than a more aggressive tread.

I would definitely go at least 35x12.5  That is only 0.9" taller and 1.7" wider than the stock tires.  It will be a slight change, but not enough to have issues.  They won't stick out past the fenders because the stock wheels sit in quite a bit.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Gas Prices

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      By Coastie05 · Posted

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      Gas Prices

      By Chuck FB · Posted

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !

      OTA updates and radio still cuts out

      By wxman13 · Posted

      Just wanted to get a idea of how many of you still have problems with your radio cutting out during the first few minutes of driving, my 2024 GMC Sierra still does this after a little over 2 years of complaining to my dealer about it, and OTA updates no longer complete, the check for updates in settings is greyed out for the second time while trying to install a update, my dealer took about a week to play around with it the first time this happened, and somehow got the check for updates to work, even though it would always show system is up to date when I knew it wasn't, now again 1 month later its greyed out again when the OTA update N25-F163BU tried to install, which ironically is the update to help with reliability of future updates.
