Small tire size increase- calibration needed?

[kenmore99]

Have a 2022 KR with 10k miles stock 275\60\20 Pirelli tires--want to level front 2" and get Falken Wildpeak atv3 275/65/20--from a 60 to 65 could I get away with not recalibrating odometer or would I still need to reprogram-truck custom shop says no- thanx for replies

I didn’t, I went from 275/60R20 to 285/75R17 so about an inch increase. I just checked my speedo with a gps app and it was reading right on the money so I didn’t mess with it!

As stated, just check your displayed speedo using a GPS. Check it at various speeds. 20mph...40mph and 75mph. If it's dead on or superclose, I wouldn't worry too much about it.

You’re fine. With a 2” lift you can fit up to 35s and have minimal speedo change.

In the past the dealer's people could select a different tire size only if it was offered with its trucks. If the difference is going to be 4 mph at 65 mph then I would make a mental adjustment and forget about "fixing" it.

Of course you should. It’s increasing over an inch right? Get a FORScan cable and do it
