Factory summer tires on my 2017 DGC SXT will soon need replacing - probably this spring. Factory size is 225-65R-17. I love my winter tires @ 225-60R-17 but tend to over rev engine when going above 65 MPH. For summer tires, I'm thinking of wider tires - changing to 235-60R-17. Yes. Speedo will show 60 mph but real ground speed will be 59. Anyone using 235s / 60R-17? BTW: 235/60-17 is same tire size as Toyota mini-van, Are they better / smother ride over the rough country roads? Would you pick this alternate tire size size again?
