34.3 " tires (275/65R20)

[DanRob]

Just bought a 2020 1500 Classic Night Edition last week. Love the truck, hate the lights and tires. Put some new bulbs in and that made the lights alright until I upgrade to LED. Looking at a set of 275/65's. I was wondering if anyone had this size on their truck with stock suspension, and if there were any issues. I'm looking at putting a 2.5" leveling kit in a couple months; however, would like to put the tires on before too much snow is down. Any tips or opinions are appreciated.

Not sure about stock, but I ran them with Bils at 2.1” no problem .... Bils are a way better way to level vs a top spacer

Thanks, I will keep this in mind when looking to level.

I've read on the forums that several people reported no issues with the 275-65-20's on the stock suspension.

Definitely true since I bought my truck in March I've spent around 3 k in upgrades so far. It's addicting and really fun to take something and make it better or more unique.

I have that size. No rubbing and no lift.

I have that size, and they're fine. I've found that I can run 55 PSI without adding to the harshness of the ride - but that may depend upon the exact tire.

You guys that are running the 275/65/20, how has the added tire weight effected performance (seat of the pants) and fuel consumption, adding a typical average of 15# at the wheel, which is considerable, especially going from the 32" tall Goodyears along with the added height.

I put some LT295 /60 R20's on my truck a couple of months ago. I have a 2.5" leveling kit in the front. No issues whatsoever. Initially, the tire shop thought they could get 35" tires on, but they were a little too big and would rub the inside well on turns. These tires are basically the equivalent of 34".

Here's a good web site to cross reference tire sizes and help you compare.

I have Goodyear Wrangler Duratracs LT275/65R20 on my Sport with no issues what so ever. They are heavier and I do run higher air pressure. I really have not noticed any difference in performance, and hard to say about mileage since they have been on for so long.

Not the same size, but I had 285/60 20 on mine, which are just about the same diameter and wider, on a stock 2wd with no rubbing issues, so I imagine they would be fine.

I went from a 49lbs tire the a 72lbs tire. And that is stock 33.1” to 35.1”

Re-geared from 3.72’s to 4.88’s

Lost maybe 1 mpg

I have that size on mine 2019 1500 classic with 2.5 leveling kit.

mine barely rubs at full turn I also have 20x10-24 wheels and zone UCA’s

I went with nitto's that were XL rated and are 34.3 tall also IIRC . I can't remember the weight but they were 20lbs lighter than the E rated BFG 35-12.50 KO2s they replaced and are only half inch shorter and an inch narrower than the BFG's. That same 275-65-20 Nitto is also available in an E rated version thats much heavier and not really needed on a half ton.

I have Falken Wildpeak AT3 in 275/65/20 on stock 20” rims. They are E rated and I run about 50psi in them. The truck is leveled +zone UCA and 1” spacer in the rear.

The tires are great but heavy. I notice it on washboard roads and little bumps going sIow. I also feel like I lost a little on the acceleration with the extra weight. I got the E rated because I believed they would be more puncture resistant and I felt like I was patching the stock tires all the time. Now I am having second thoughts about the benefit of that.

I have the 3.92 gears so the truck is still quick and I am putting on a borla catback and core rear arms next week when they show up. I am also going to air down to 40psi and see how that feels.

275/65R20 BFG KO2's E rated on 20x9 Fuel Maverick -19 stock offset. Wanted e rates for towing, no noticeable difference in performance or gas mileage for me with 3.92 rear. I do notice a bit rougher ride which bugs me a bit but I need the durability and load rating for towing.

Out of all things to buy, I hate spending money on tires, has anyone had any experience with SureTrac tires?
