KO2's have a stiff sidewall so no problems. Goodyear Duratracs had a squishy fishy feel though and the Duratracs I had were E rated (295/65/18's).

As for calibrating your speedometer the Hypertech speedo calibrator works just fine.

Funny but I did not swear I don't know why it blocked out the name of the world war 2 jeeps Willis (I'll spell it diffrent.) As far as speedo goes I went from stock 32 to 34 inch and my speedo is 4 kms out at a hundred so I did not bother buying a calibrator. That was gps btw

As long as you can accept that your mpg and odometer readings will also be 4% out. It may effect your factory nav as well if you have it.
