225/75R16 vs 245/70R16 on an AT-KO

dgeist · **Posted:** Mon Feb 25, 2008 11:00 am

I'm debating on getting one of either 225/75R16 or 245/70R16 in the BFG-ATKO to replace my stock Crapyears. I need to stay close to stock diameter (due to things like my garage door) so I won't likely get a lift even though I'd like to.

I don't like the look of the existing tires (too rounded/passenger-looking)
The questions are:
- Are the BFG's more square-profile such that they'll look better than stock even in the stock dimension?
- Is there a reason the two sizes are so different in price?
- Based on what I'm reading on their site, it looks like the 225's are higher load-rated anyway
- With stock size, will my on-road traction decrease compared to the crapyears since it's an AT tire?

I went with the 245/70 AT KOs and haven't looked back. I have no rubbing issues and currently running stock lift. They do look alot better than the Goodyears (get complements all the time). IMO the AT KOs do better on and off road than the factory Goodyears. Someone else will have to chime in on the 225/75s. Good luck with your choice.

I would say the extra $20 per tire is for the extra width. It doesn't seem like much, but it is. Also keep in mind that a wider, heavyer tire will add a small hit to the MPG- not like an MT will, but it will have more rolling resistance. What kind of wheeling do you do? If you get a lot of mud or sand, I'd do the 245's - rock or snow, they 225's. Not that the .9" difference will be that much, but it would help float you in some situations and bite in others.

Anyways, just go ahead and lift it and go with the 32's :twisted:

Most wheeling is limited to existing trails (packed dirt or gravel). No crawling, no deep mud (if avoidable). I'm in Georgia, so the natural soil is red clay that turns into a gooey adhesive mess when wet (so no help short of MT's there...). Some light/medium towing is encountered, but nothing heavy enough to make the decision for me. I mostly want something that's durable, appropriate for any terrain that I'm likely to encounter, and will last a really long time. I would like to retain my 20+ fuel economy if possible, too, since most of my miles are on-road.

I went from the Stock ST's in 225/75r16 to General Grabber AT 245/70r16, pretty similar to the BFG AT. The extra width seems to make the Jeep handle and corner much better and it actually looks like a real Jeep now. I don't notice much in the way of MPG loss (must be a little though).

Take a look at the General Grabber AT2's. I have run the BFG's too and I think the Grabbers are just as good and cost a lot less.
