What are the biggest tires I can put on stock rims with no lift/level? The truck is a 2019 1500 bighorn. Stock tires are 275/65R18’s. Looking for taller tires mainly, but I wouldn’t mind a little wider too.

I put 33x12.5r22 on stock lift. No rubbing. I’d imagine that’s close to the biggest tire on a stock ride. You can find a tire that will fit the stock rim. I don’t remember the website for that however.

Assuming this is a 5th Gen/DT truck we are talking about, RAM downsized the stock tire from a 33 to a 32" dia.

I am running the Blizzak DM-V2s that I had on my 4th Gen at 33" tall on my '20 with no issues.

I ran 35x11.50 on my 4th Gen at stock height with no rubbing, and am hoping for the same on the 5th Gen. May try 35 x 12.50 even if I need to use spacers (shouldn't take more than 10mm at most).
