Yes, I am a newbie, but the only practical reason I can see for increasing the tire diameter is to increase ground clearance.

But is the extra 1/2" or 1" in of clearance worth the money, lifts, potential body mount chop, etc?

Are there other reasons? What am I missing?

You answered your own question. However, the stock size looks a little silly with a lift. In that case, it's a slight aesthetic preference.

Look at it this way, if you were offered two different sets (one stock, one bigger) for the same price. Which would you choose?

It is worth it, depending on what kind of trails you're going to run with what kind of obstacles. In rocky terrain particularly, larger-diameter tires make a big difference on what you can get over and climb.

OK...I get that.

But perhaps my math is wrong. Right now I have the OEM 265/70R17 which provides (according to spec) 9.6" of clearance. For me to add an inch of ground clearance (a 10% increase), I'd need to increase the tire RADIUS by 1" (or about 25.4mm)...yes?

To get 25.4mm additional sidewall height one has to go to an additional 36mm of tread width (25.4mm/0.7)...yes? Adding 36 to 265 means a tire like a 305 / 70R17?

A tire that big is going to require lift + maybe chop + no more indoor parking, yes? (maybe this is for another thread... ;-) )

LOL -- Maybe ******* chicks ;)

As I said to the wife this weekend.... I have no need for a winch or huge tires, because if there is an obstacle that requires I winch my $30k ride over it, then that means I'm going to be turning around and going back the way I came. haha I've been 4-wheeling on some pretty major trails, and I've never come across anything I couldn't get over with a pretty stock configuration. Some guys abuse their equipment on purpose, but that seems like more of a crazy obsession to destroy your toys and cost yourself money?

Spot on Hakrjak :clap: ... It's a personal preference but I agree with you totally... And if you really get stuck, there are other (albeit slower, manual) options to get you out.

I've been amazed by the difference a small lift and one-size-up tires makes on keeping skid plates and bumper off of rocks. Even on relatively tame trails, .75" of increased clearance can make a substantial difference in how often your belly makes contact with rocks. It's probably not enough of a difference to make the truck with bigger tires wildly more capable but bigger tires are the only way I know of to increase clearance between the ground and your differentials.

Plus, a lifted FJ with stock tires looks a bit like a rollerskate... at least mine did.

Larger diameter tires will make rocky or rough trails feel smoother, like when semi trucks hardly feel holes that will swallow your Prius. A

No lift or large tires on my FJ either.

However, I did opt for the 16" TRD rims and a 265/75R16 tire. It has the same O.D. as the stock 265/70R17, but a softer ride on the rocky trail of the Summit, because when airing down there is more side wall to cushion the ride. Also, I have the LT version of the tire so I have a Class C sidewall rating. The stock FJ tires are the P (passenger) version, which have a lighter sidewall ply.

Also, it challenges you to become a better driver, as you must pick your driving line to avoid obstacles.

The only extra armor on my FJ are rock rails by Man-A-Fre.

Ground clearance, traction, floatation, agility, looks, proportion, your sexuality!
