Seems about 1-2mpg hit from what I read FYI.

Trying to get this thread back on track though.
Anyone with a 200 on 275/65/18s please GITT and share thoughts.

Got the Coopers in 275/65/18 installed on stock rim, stock LC. I don't see/feel any difference so far between the trivial size difference. Note this is not the LT counterpart that weigh 11lbs more each. Appears the same in the wheel well as the previous 285/60s did, if anything they may fill them slightly more as they are .61 inch larger in diameter but more to my concern they do not look any skinnier than stock, basically same stance as before, despite the .39 loss in width.

Hopefully this can put someone that is looking at a tire that is not provided in the stock size of 285/60 and doesn't want to go to 285/65, at ease.

Your speedo will be more accurate now. When I ran that size it was dead on.

Thanks for the info! Reversing with the wheel turned hard left produces some rubbing in the passenger front but so did the stock 285/60 Nexen tires the previous owner had. Otherwise, really satisfied with the set up so far. Super quiet.
 
Just for reference -

On a LC200, the following are the Recommended Cold Tire Inflation Pressures for the tire sizes under discussion in this thread:

P285/60R18 - 33psi F/R (Stock)
LT285/60R18 - 46psi F/R (Same for Load Range D or Load Range E - no difference)
LT285/65R18 - 42psi F/R (Same for Load Range D or Load Range E - no difference)
LT275/65R18 - 45psi F/R (Same for Load Range D or Load Range E - no difference)

NOTE: Recommended pressures are different for LX570.

What pressure should I fill up to for:

2013 LX570
275/70/17 KO2? I believe it’s the E rated

I don't know - BFG doesn't make an ISO-Metric 275/70R17 KO2...

If you have LT275/70R17/E 121/118R tires, however, then the RCTIP for them on your 2013 LX570 is 38psi F/R.

Anyone have experience with this tire and or size? How does it compare to the great KO2? Will be used 90+% on road most LC’s. I’m going to replace the current 35/12.50r18 on my new LC. My wheels are 18x9

What’s the difference between iso metric and the ones you listed?
 
What’s the difference between iso metric and the ones you listed?

ISO-Metric: 275/70R17
LT-Metric: LT275/70R17
P-Metric: P275/70R17

All different construction and built to different specifications. Each requires a different cold tire pressure.

It's important to recognize the difference.
