Replacement Tire size

I purchased my 2004 WJ Special Edition used and it came with off-brand American Prospector sized 235/70 R16 tires . I need to replace them and I know the vehicle left the factory with 225/75 R16s. In fact the spare is a Wrangler ST in that size.
The WJ does not have the Up Country package and I have no plans to lift it anyways.
Would I be best to go back to the original size of 225/75 or stick with the 235/70 that's on it now.
I wouldn't call myself an off-roader, so I am really just looking for an all around tire like a Wrangler or Destination LE.
Thanks in advance.

P.S. If there is already a post addressing this, please direct me to it. I had an awful time in the search tool trying to research this.

Hey bud,
In my opinion it really doesnt matter, due to them being so close in size. When you convert that size to the english language you get 225/75/16=29.28in and the 235/70/16=28.95in (hopefully my math is right). But as you can tell the size difference is minimal and wouldnt affect speedometer and the revs per mile a whole lot. What I would do is go to the tire store and compare prices between the two and also what they have in stock. I know when we threw new tires on our jeep we were going to stick with stock size but they didnt have them in stock (235/65/17) but they did have 245/65/17 which is about an half inch difference in diameter. Hope this all makes sense and helps you in your decision.

Hey Maz, thanks for the reply. You know I didn't consider the cost between the two sizes, but I will now in my search. Do you think the thinner 225 would give me a slight boost in mpg?

The size difference would be so minor of a difference it isnt worth worring about. However would be best to switch to the 225 since you already have a spare this size .

WarInc makes a good point on sticking with your spare tire size. That way if you do get a flat it isnt a big deal running your spare for long amount of time. That wouldnt be the case if you had the larger 235. In regards on the better mpg. Thats hard to say. Were talking a 10mm difference in width which is roughly .4in. Again that is minimal. Ill tell you that we were running 235/65/17 and we just got new Firestones and the 235/65/17 were on back order so we went with 245/65/17 which is about a half inch larger in diameter and the 10mm wider. Before we put the Firestones on were were getting right under 18mpg and now with the little larger tire were getting a solid 17mpg. Not to mention rotating mass because the old tires were POS and had very very little tread. I would take WarInc tip and get the stock size due to your spare tire and if that size isnt available in the tire you want then get the larger tire. Just my $.02

you're best bet is going to be to stick with the stock tire size, and get the same tires as the spare. in this case you can do a 5 tire rotation, and get some use out of the spare instead of having it dry rotting in the tire well.
