245 75 17 or 255 70 17

I just got my RC 2" lift with Robby's spacers installed and am looking to get bigger tires. Which size should I go with. I would like something taller and wider but do not want any rubbing issues. Both of these sizes stated that they would not rub on the sticky. I am just looking to see what size you guys use and why?

thanks

Both sizes are almost the same rolling diameter... 255/70/17 is 31.1" and 245/75/17 is 31.5". Obviously the 255 is about .4" wider than the 245. Note these dimensions are approximate. Either setup should be fine.

I lifted my XK with the RC 2" kit and switched to 245/75/17's. I am pleased... no rubbing. I didn't go wider in order to keep rolling friction down, but a wider tire does look nicer! I guess make sure you can get the tire you want in the sizes you are considereing.

You can see the pix in my garage (click in signature).

I think its worth bending over the pinch weld for 265 70 but then you need spacers and stuff. I would pick a tire. If it comes in both sizes go wider! More rolling resistance however larger contact patch means better traction!

Interesting thoughts.

Wider is not better for winter driving or fuel economy. It LOOKS tougher and is better for mudding, but unless you are mudding more that spending time commuting to work, I say get a setup primarily for street use and occasional off road capability.

Of course, you have to decide what you're using your XK for and what tires will suit your needs.

I vote for 245/75's. Plenty wide enough, probably a bit more economical on the street. But either is fine. Might just want to go with what you can find for less money at the tire stores.

I have the 255/70's. I kinda like the wider look better. Th 245/75 will fill the wheel well more, it all depends what look you like better I guess. here are a few pics of mine. https://www.jeepcommander.com/forums/...hp?albumid=223

I am nearing the same decision...

I would like to know from people with the setup some specifics that aren't quite answered or buried throughout threads:

On the RC and RR, does the difference in lift afford enough to increase tire size?

Without Spacers and trimming what rubs?

________RC_|_RR_
245/75 |____|____
255/70 |____|____
255/75 |____|____
265/70 |____|____

Without spacers with trimming?
With spacers without trimming?
With spacers with trimming?

not sure if all those charts could be completely mapped but man those are the details that would take the guess work out of my decisions...

Looks good, I would like the tires to sit more flush with the fender flares, but I don't even think that 255's will???

What kind of mud flaps do you have? I need to get some.

I wasn't aware that there was much effective difference in those lifts. I have Rusty's 2inch lift. 255/75's with 1.5 inch spydertrax spacers. I had to pound down the pinch welds on the front and trim the plastic inner wells.

I don't know that you can exactly go by what the manufactures call their lift but if you had exact dimension of the parts you could identify if any real measurable difference.

I did a 2.25 OME lift and went with 255/70/17. Yeah they look good, but next time I am going to go with a smaller size. When I take turns a little to fast, the tires will rub and it feels a little sketchy.

I tend to drive a little fast though.
