Recommended tire size for 4 cylinder engine?

Post some pictures and tire size
33 inch tires
12.5 by 15

Again. My teenage boys convinced me we needed these wheels. We live in Idaho. But I needed a back up vehicle too. So we chose a wrangler instead of a UTV.
I don’t wanna wreck the engine/axels with these tires.

Thank you so so much for your help.
I really appreciate it.
Having buyers remorse as this isn’t a great mom car. I’m a sucker.
They're a fun family vehicle when the top's down in nice weather and the family's enjoying their time together. You can't say that about many other cars. And you're entirely welcome. :)

Thanks much. My dad passed and left me a little money. I was just looking for ways to connect with my boys and fulfill a dream of mine. He’d be happy. I hope I chose the right one! Thanks again. This helps my nerves a lot as I wait to go pick it up!
 
Thought I'd get another perspective than my own on what my next set of wheels and tires might be and stumbled on this thread. I'm currently rocking the stock wheels and tire size on my 1999 TJ Sport with the 2.5 squirrel power, manual trans. I don't DD it but I do like to cruise around and that requires at least some interstate driving to get where I can take her off-road in Alabama. I'm not doing any rock crawling out here (not Arizona anymore!) so it's mostly foresty-type trails.

I'm looking at going with a 15x7 set of wheels and 235/75r15 tires at just under 29" (specifically duratracs) and wanted to get anyone else's thoughts, especially if you've run a similar combo. I would prefer to not have to do a lift or to keep it at under 2 inches if I do, and also would like not to have to regear. If I was going to regear, then I'd be looking at going larger, in the neighborhood of 33s and a lift but I like the idea of staying a little lower and staying closer to stock if it still is useable on the highway while still making me a little more capable for the lighter trail work I'm doing.

Any input would be appreciated, thanks!
 
235-75-15 are great. They would fit on your current wheels that are 15x7 and its hard to beat oem wheels for quality and fit.

Thanks! I think that is where I wanna go with the sizing, I had 35" patagonias on the JL and while it was a beast off-road, I don't need that capability anymore and want something a bit less. The stock rims are in rough shape but there are lots of options for 15x7 steelies with an 8 pocket, probably end up with one of those.

Sorry to hear about your Dad. I'm sure he'd be happy that with your reasoning. Enjoy your Jeep and keep in mind that you're giving your sons a special gift... your time.
