Hi All!

1 1/4 is on the aggressive side for 275s on the 250, but you're probably fine, you'll just be closer to the edge than most. Most guys run 1 inch and call it a day. At 1.25 the front will likely kiss the liner at full lock, and the rear bumper corners are the usual spot that gets friendly with the tire when you're loaded or hit a dip. Worth a test fit before you torque anything down, turn the wheel lock to lock and check both sides, then bounce the rear a little.

One real thing since you already ordered, make sure they're hub centric and the right bolt pattern, and decide bolt on versus slip on. Slip on needs longer studs, bolt on carries its own. Either way torque the spacer to the hub properly, that's the part people rush and then post a horror story about.

You'll be fine, just don't be surprised if you end up trimming a tiny bit of liner. What brand did you go with?
Thanks for that, I will send these back. Do it right do it once!
 
Welcome and congrats on the new rig. 20's with A/T's actually looks fantastic IMO and will generate more grip on the trail than you'll likely need for a long time. I'd expect ride quality to improve some, but some of the rough ride on these is simply the nature of the dampers. You're starting in the right place, I'd avoid E load tires if your wheeling use allows it and I think you'll be very happy. Beautiful truck!

I thought about going that route after bringing our Premium with 20"s home. I went down to 18"s with slightly larger than stock tires- happy camper. One good thing about the LC250 platform is that wheels & tires look at home on this beast in 20" down to the right 17" if you choose wisely. I prefer the 18" for just that little extra clearance between the wheel and the brakes, but as long as you do your homework with outside diameter and offset for clearance you are good to go.

Luckily lots of forum members have blazed that trail already:


Those are a lot of posts to go through, but worthwhile to see what rubs, what doesn't and whether there will be other mods required to make your preferred package work. Included for OP's benefit ;)
 
So here is the after pics! Long read but some tidbits that may interest some.
I first put 1in spacers on to hold me over till I decided on tires to fix what I considered a very weak stance. Then I went down the tire rabbit hole! Did not think tire selection could be so stress full! I think I have now read this entire site! Was taking my time but then my tire place had a buy 3 get one free so the pressure was on. Came to the concussion I was going with 275/65 keeping the 20’s for the look. I plan to get a set of 15 or 18 take offs that I will swap out for off road weekends (once I get to that place where the newness and what I payed doesn’t make me timid, that was about 4 months with the last rubicon) . So the focus was comfort with with light Off road capability and a bit tougher look that I think should be standard on a Land Cruiser. I realy wanted the new Conti’s but that size only comes in an e, so I ended up with brigstone as the second runner up. Low noise good comfort and a modest but notable look. I ended up keeping the spacer on and you can see from the pic it puts the tire just about perfectly paced on the fender. No rub that I could creat, but have not been off road, but from what I can see, not going to be in issue for light off road. Intersting note. The spacers actually improved the ride quality alone with the stock tiers. I was not expecting that. On my rubicon you put them on to improve highway manners, Not comfort. That plus that additional side wall it rides really nice. I think I may have lost a bit of steering response but I want to let them wear them in a bit before I have a verdict on that. Mpg will be the next thing I am curious about. I ran the stock tiers down at 33 just to get what I thought was an acceptable ride. Never got above 19 mpg. I believe I can run this setup at a higher psi so it will be interesting where it lands. I have them at 37 currently. Curious if anyone out there has had the computer adjusted for tier size change. Let me know if you have and if not what factor do you figure for milage. If you made it this far in the post, thanks for reading. Once this setup wares in I will give a full rundown on my loved and head scratchers on the truck. So far it is like my Tahoe and my rubicon had a baby and that is what I was looking for!!

Looks really good! If you wanted a subtle but noticeable look I think you nailed it. Speedo can be recalibrated for a drastic change in tire size, but like most cars, these over-report speed in stock form. It is likely closer to accurate now than it was stock. You can compare it against a GPS phone app, but you should be pretty close to right on the money. Thanks for sharing the pics!

As far as I am aware, the speedometer cannot be calibrated to a different tire size. There was one aftermarket device that someone shared awhile back, but can’t recall the details outside of it not being for me. For what it’s worth, the consensus is that all LCs are factory calibrated to the 265/70-18 or 32.6” diameter. My GPS confirms this. This would be my recommendation too: pull up a simple GPS w/ speed built into the GUI (Google Maps is actually pretty accurate with good cell reception). See the disparity at every 10mph increment and do basic math.

My perspective is contrary. If Toyota is willing to put undersized tires on 1958s without a complimentary speedometer calibration, therefor allowing 1958 consumers to over-report mileage toward warranty expiration, screw it. Know your offset and run it under-reporting. They set the standard for tolerable specification there.
