New to trucks....questions

[rwickens]

I just purchased my 'new to me' 2014 GMC Sierra SLT. I would like to put a more substantial tire on it as the stock 20" wheels and tires just seem to little.

 

Would an All Terrain 33-12.5x20 work on my truck in stock form or will I have to level the front end first? Any help is greatly appreciated.

I have a 2015 with 285/70r17 with out a level and they work great. You could put a tire with the same outside diameter on a bigger rim too

For 33x12.50 you will have to level.

I'm running 33x10.8 (275/65/R20) and I slightly rub.

Thanks for the feedback guys, that is what I thought.

 

How do you recalibrate the speedo?

I used Hypertech's Speedometer Calibrater.
