Will I have any issue going to a P265/75R/16 tire on a stock 2013 JK Sport? Factory rim, no spacer. As for calibration, it's a manual shift so assuming just a slight variance in the speedo if anything vs a need to worry about shift points.

That works out to be a 31.6" tire. You should be fine. As for calibration, yeah, with a manual, you don't 'need' to program it... speedo will be a bit off.

Thanks, wasn't 100% sure on the factory wheel aspect of it, currently have 245/75/16, without issue but they're worn just wanted to double check with those who know. As everyone can guess, you call the tire guy and he goes right into "those aren't what the Jeep calls for" panic voice.

I love when I tell someone exactly the part number I need and they go asking me what it's going on.....lol.

As far as speedo....talking a very marginal amount it's gonna be off. Going up to a 35 puts you off about 5mph up around 65-70mph range. I'd think you'll only be off 1-2mph.
