Tire width question

I recently bought a jeep TJ with 305 65R17 tires. Theses tires are nearly 12" wide and I was wondering if I could change to a tire with less width while keeping my 17" rims or will I need new rims? Thanks in advance and apologies if this is a dumb question

Not a dumb question at all! Welcome to WF.com BTW

To answer your question with certainly we need to know the width of the wheels - do you have this info or do you know what wheel is on your Jeep? What size tire do you want to switch too?

Yes you can go with a narrower tire however as mentioned how narrow you can go depends on your rim width.

You will also want to keep the overall size close to whatever stock was or what the Jeep is setup for. Going to far one way or the other will mess up your Speedo

That tire is only 32.6" tall. As the others have said, it depends on how wide your rims are.

Just as a comparison, 285/70-17 is 32.7" tall and 11.2" wide
You'd gain 0.1" on height and be 0.8" narrower.
So if your rims allow it, you can run this tire without losing any height.
