New tires

[19ramhemi8]

Good Morning everyone, question… I am looking to purchase new tires. I currently have 275/65R18 on my 19’ Ram 1500, I was thinking of getting the Atturo trail blade m/t 275/70R18 (maybe getting a leveling kit in the future). Has anyone used these tires? and would it be ok to go that size? (Everything is stock at the moment)

Thank you!

I am bumping this question as I have basically the same question on a 2025 Bighorn with off road group. I would like to go to the 275/70-18 size on the Rebel. Will they fit and do I have to have the dealer do a recalibration on the spedo?

I don't think I'd change sizes for another half inch of ground clearance.

I also don't think I'd want to run those 10 ply rated 275/70's at P metric air pressures which would leave me with TPMS warnings 24/7

I just don't think the juice is worth the squeeze for what is effectively no benefit

Personally with the understanding that tire sizes are not happenstance with regards to fitment on any individual vehicle but are in fact engineered components providing the optimal final drive ratio to match the other components/controls in the truck, I'm not going to be changing tire sizes barring some extraordinary circumstance.

Assuming you still have stock-ish wheels, yes they will fit. And yes you will need adjusted for the larger diameter. There are systems you can buy to do it yourself but otherwise the dealer can.
