As I have mentioned, in two other threads, I am new the Cherokee Forum but not new to JEEP.
I have owned jeeps since 2004 (2004 Liberty, 2005 Grand Cherokee, 2009 Wrangler, 2013 JK) and have had a lot of good advice using the other Jeep forums.
I have requested information concerning tires size upgrades for my 2019 Lat FWD (no lift) a couple of times with no response. So I am assuming that 1) there are no KL owners on this site or 2) no one has upgraded their tires or 3) no one likes KL owners that are requesting information on this forum.
Please prove my assumptions wrong.

Hi I just bought a 2019 Cherokee 4x4 limited. I hope you stay on the forum because I have some questions too.

Hello, I am new here and also to Jeep. We own two Cherokee Latitude FWD (just bought another Saturday). As for tire upgrades if you do upgrade size it will throw off your speed. stock size 225/60r17 (size we have) vs 225/65r17 the 65 will jump about 3 mph higher than the 60 series. This web site is a great site for comparison https://tiresize.com/calculator/

You have a FWD so you are somewhat limited as the suspension is different and there is less room. Generally anything 29.5" and smaller should work.
