I threw some orp wheels and oe tires on my limited tonight. Love the way it drives so far. Smooth.

I thought I was going to save a lot of weight. The 20” setup is 73 lbs. the 17s varied from 69-70. Both sets of tires nearly new. Hard to justify on weight alone though the weight is likely farther from the hub w/the 20s which does hurt. Thought the data point would help.

Looks better in the flesh than photos.

Funny, I'm looking at doing the same thing. My math is the same as yours. I've got several sets of wheels I'm looking at right now to purchase.
I'm coming from a 2015 BMW i3, so the 4Runner fuels costs are painfully obvious, but I'm banking on Toyota reliability. Just broke 500 miles on the 4Runner odometer. First Oil change will happen in two more weeks when we reach closer to 1000 miles.

For some reason, I remember each pound at the wheel is roughly the same as 40 pounds of cargo...so dropping 3 pounds at each wheel is the same as dropping 3 pounds x 4 wheels x 40 pounds = 480 pounds of cargo.

I'm sure someone can do the math...but when I did the research a long time ago, I chose 40 pounds as a good engineering estimate to use.

Another good estimate to use as a rule of thumb

100 pounds of cargo costs an extra 10 gallons of fuel a year at 12,000 miles a year.

So the wheel change above will save roughly 50 gallons of fuel a year... or $200 per year at $4/gallon.

A recovering engineer,

Another neat formula
$10/hour is 20K per year....
$15/hour is 30K per year...
$30/hour is 60K per year....
or double the hourly rate is the annual rate in thousands per year..
close enough (2000 hours per year= 50 weeks x 40 hours) to work.
and the reverse is true too
50K annual salary is about $25/hour.
80K annual salary is about $40/hour.
But no matter who you are, those bureaucrats and politicians who happen to have jobs in government keep wanting a bigger cut for all their good ideas.

All those numbers are cool but....... does ride comfort improve ? When I had Venza it came with 20"s & I felt every bump & gutter , switched to 18"s for more rubber on road & sure did feel it right off ! Better handling also

I have my OEM 20" in my garage and have 17" rims for both my summers and winters. I much prefer the ride and bigger sidewall of a 17" rim/tire combo

100% with you on this. Love the way it drives now. Smoother, better ride. The lower sidewall gives you a hair better steering response but the tradeoff is totally worth it. And, it's a big ponderous pig so who are we kidding?

I did notice the change in steering right away. I have to take corners a bit slower now if I'm coming at them at speed. I do enjoy the ride much better overall. I will say this though, the nightshade trim with the blacked out 20" rims do look very sharp. I saw one this summer (rare around here) and it looked real nice
