Upgraded the stock Michelins to some Duratrac tires! The tires are 295/65/R18 and have an E load rating which was important to me. I searched these forums to death and never found anyone with upgraded tires using the stock 18's on the AT4. I think they look great! :)

Stock Height with Toyo Open Country AT3's 35x12.50
18s or 20s?
I just had the same tires, 35x12.5-18 installed. Ride so much better than the 295/65-20s I replaced. I think the extra 3/4" sidewall makes a huge difference. I need to go get them rebalanced though, they are not as smooth as the the BFGs I took off

What wheels? Offset? Pics would be great too! Any rubbing at full lock or under compression?

I have a 2021 and have been kicking around the idea of going to 18” wheels with slightly bigger tires. Not interested in lifting or trimming…….been there and don’t want to go there again.

Method NV HDs, 18x9, +18 offset. 0 rubbing on compression or full lock. 0 trimming. I am leveled 2.5" though, and I did remove the very bottom little airdam/valance. I did that the day I bought the truck 1 year ago.
The 295/65-20 on a 0 offset had 0 rubbing as well, 0 trimming.
I don't have any pics, I'll take some
