It's cool that your Costco has the Defender for the LC. My local Costco will not put those on a Land Cruiser because they are not listed in their computer due to lower speed rating (not V). At least at my Costco, if a tire is not listed in the computer for a vehicle, they won't put it on.Great timing for this thread. I have a roadtrip from Bend, OR to Denver coming in about 3 weeks. I have been running KO2s on my trucks since 2016. But I am doing little offloading anymore and what I do is rather mild. Think 90% pavement, not towing. 5% pavement and towing. 5% "mild off-road". I tow a 5700# travel trailer with ~700# of tongue weight but IIRC, the LC is rated for 8100# and I would assume that is stock. So although a higher load rating is a plus, I don't know if it is necessary. With my current setup I get 14.5 MPG combined and ~16 on highway. (No need to even discuss towing MPG!) With gas here in Oregon at $5/gal I would love to get a couple more MPG and better highway ride quality and less noise. All that said, I have a "mild" 2" lift (OME, 2721/2700 done by Slee a couple months ago).
I got a bit lost in all of the terminology and codes as I was trying to follow the thread. But a quick check on the Michelin website shows me that for my 2021 HE 18" wheels they only offer the following:
- Defender LTX M/S2 285/65R18 125S
- Defender LTX M/S 285/60R18 120H XL BSW.
- X LT A/X 285/65R18 121/118R BSW
- Latitude Tour HP 285/60R18 120V XL BSW
Now I guess I could change to 275/xx but I have always run the 285/60s or 285/65s so I am not sure of the tradeoffs of doing 275s. I did consider 275/70s at one point but didn't want to do any cutting and Discount Tire would not put them on due to the tight fit.
So, given the type of driving I am doing now will I see benefits from a switch to either of these tire choices and if so which would you recommend?
Thanks in advance for any suggestions. I have about 3 weeks to do that swap and it looks like Tire Rack (or in the case of the Defender LTX M/S2s Costco) have them in stock.
Note that the 275/65-18 P rated Defender LTX/MS is a bit wider in tread than the 285/60-18XL Defender LTX/MS. So with the 275 size you get wider tread and a taller tire. The 285 is overall wider, but more of the width is in sidewall bulge and not tread compared to the 275.
