You're joking right?

If you put a larger diameter tire on the odometer and speedometer will be slightly off on the low side. Once programmers are out that can be fixed.

Larger tires will not do anything to your 4x4 system....

Re: 275 55 20 ? will it fit on stock 20s

My dealer adjusted the speedo as close as possible after installing the A/Ts on the aftermarket Mopar black wheels. It still shows my MPH just a shade below my actual speed. Prior to that, I inquired with a Hypertech dealer, I decided to use their aftermarket speedometer calibrator. Long story, it didn't work and the ABS light remained on even after upgrading the firmware. No issues returning it, but I'll be waiting for SuperChips to release theirs. (they post on this site)

It doesn't void any warranty, but remember that your actual MPH is slightly higher. (mine is approx. 5% off right now +/-) Since I don't have the 430N radio which shows how fast you're going, I usually take a look at those stationary signs that display. (which are probably not the most accurate) It usually places me about 3mph over my speed if I'm going between 55 and 65. Hope this helps.

I find this automated calculator very helpful if you want to change wheel or tire sizes. It'll tell you what are the net effects .. http://www.rimsntires.com/specs.jsp . Cheers.
