Ride quality on stock tires

[glider]

The XLT has 225/65/17. The lariat has 225/60/18.
Does the difference in side wall height effect the ride quality? I'm under the impression the narrower the side wall the bumpier the ride. So why put 60's on the lariat?

Logically, yes. In reality, no.

They shorten or lengthen the sidewall accordingly so circumference is same for speedometer accuracy (so if’s you put 19’s would go to 55, and then 20’s would go to 50, and 21’s down to 45…). Some added width going from the 225 to 235 or even 245 also helps ride characteristics but the tires themselves have different ride quality too.

You won't notice any difference from something like that unless it's a pretty drastic change.

My '22 Lariat 2.0EB has the Michelin Primacy 225/60/18 and the ride is excellent. I also carry tools and assorted stuff all the time so there is weight in the bed - maybe 200lbs most of the time. The Mav is far more enjoyable to drive than the 2016 GMC Canyon V6 I had.
