Purchased a new Volvo XC 90 in May 2021. In January 2023 (with 30,000 miles) I took to the dealership with a very loud thumping road noise. All four tires were worn unevenly. The center of each tire had less tread depth than the outside of the tires. They said that was causing the loud thumping nois…

Thanks to all for the information. Tires were rotated at all oil changes. I checked the tire pressure before all long trips. Always set to 38. That’s why I was wondering if on long trips the tires would be constantly heated up and tire pressure increased accordingly. If so, would lowering tire press…

If the tires were only rotated at oil change then you may have gone 10000 miles between rotation . I think your vehicle calls for oil change at 10000 miles or 12 months .

Oil changes were between 5,000 and 6,000. One went to 7,000 while on a trip. I was originally wondering about the tire rotation but then didn’t think that was the factor as all 4 tires measured the same when they were replaced. So confusing.

Some tires on some cars wear strangely. Just a fact of life and 30K from a set of tires is OK wear. Not great, but OK. Just follow the manufacturer’s recommended pressures.

Just to be sure - the 38 psi is on the car’s sticker, not the number on the tire side, correct?

yes the 38 psi is on the car front door

Thanks, everybody for all the tips. I guess my expectations for mileage on the tires were a bit too high.

One more point - at 38 psi you might still be getting more miles, even though the center is more worn. At, say, 35 psi the tire might wear more evenly, but faster because tires heat up more at lower pressures, because they flex more. You will also get slightly better mpgs at 38 psi, and slightly s…
