We swapped from 20-inch wheels to factory 18-inch take-offs. Got the benefit of more sidewall without increasing overall size. This info is helpful though.

I’ve been thinking about doing this. I have a 2022 Nightfall Edition. What tire size did you go with?
@Mickey
Not sure about the exact size. They were OEM take-offs from a 2024 X-Line model.
How do you fit a 15-inch tire on an 18-inch rim?

The photo shows 18-inch rims. Could be a typo? I was confused too.

Yeah, it was a typo. I didn’t catch it before posting. This forum doesn’t let me edit, but the correct tire size is in the photos.
@Myles
Makes sense now. I was lost until someone pointed that out.
Isn’t an 8% increase in sidewall height a bit minor? Does it really make a difference?

The wider tire adds surface area for better wear. A truck tire also has more steel belts, making it stronger. The specs for my tires are 265 (width), 60 (sidewall), and R18 (rim size).

That makes sense for durability. I checked the numbers here and it doesn’t seem like a huge comfort gain though: 245/60-R18 vs 265/60-R18 Tire Comparison - Tire Size Calculator | Tacoma World

Thanks for sharing the tool. I didn’t do the math before making the switch, but I’ve noticed less wear and good handling over two years. Off-road and snow performance has also been better with the all-terrain setup.
This is helpful info for when I need new tires.
Does the speedometer reading change much?

Speed should be off by less than 2.5 mph at normal highway speeds (under 80 mph).

That’s good to know. I’ve had two Tellurides and usually stick with Michelin Primacy Tours. They last around 50,000 miles, but they’re pricey. Changing things up sounds tempting.
I’ve had three tire blowouts on my 2024 Telluride this year. No off-roading, but two tires needed replacing. They were Continentals, and I’m not impressed.

That sounds terrifying. I’d be really concerned too.
This sounds similar to the X-Pro package setup.
Our 2025 SX Prestige came with 265/50R20 tires. We’re in Idaho and use winter tires seasonally. We had a set of 245/60R18 winter tires from our old Highlander. A tire shop confirmed the fit was fine, so we only had to get new TPMS sensors. The winter tires are about 3% smaller in diameter but slightly narrower, which I prefer for winter driving.
