17" to 20" rim upgrade

[mlundquist]

Hi - I recently purchased a 2013 Tahoe with the standard 265/70-17 wheel tire combo.

 

I just purchased some 275/55-20 GM oem wheels from someone that upgraded their 2014 Silverado. This wheel tire is an upgrade that was available for the Tahoe.

 

My question is do I need to do anything to the computer/speedo after installing the upgraded rims/tires?

 

thanks.

I think you'll be fine - your new tires are less than 1% larger in circumference than your stockers.

 

 

My 20's were slightly bigger difference from my OEM 18's, and I never had an issue. If I did, everyone that knows me knows that I'd be ranting about it on the forum ..

You'll need to program the TPMS. Other than that no change, they're the same diameter.

Oh yeah ... forgot about that stupid thing ...

 

I have the light glaring in my eye all winter long ....

I bought 17"s to run as winter wheels, My 2011 Silverado came with 20"s. Getting the TPMS warning light now, it's easy to ignore.

I have the sensors in my winter wheels, but it's not worth the trouble to try and reprogram them for 4 months out of the year. One time I tried & the stupid thing locked up on me, requiring a trip to the dealer (under warranty, of course) - once they waved their $2,000 magic wand over the thing, all was well. Not taking that chance again.

 

I ought to remove the stupid things and hawk them on eBay for some Christmas money ...
