New Tire Size

[JMuir]

Hi All,

New to the forum and had a question. I have a 2015 Suburban LT (I know it is not a Tahoe) that I am replacing the stock tires. The new tires are a slightly bigger size, going with 275/65/18 instead of the stock 265/65/18. Does anyone know if I will need to have the computer reprogrammed to accommodate the larger size or is the size difference small enough that I the reprogramming is unnecessary.

Thanks
John

You will be fine that tire is hardly bigger. Speedo might be off 1/2mph at 60mph lol

Thanks massivespl. That's what I was thinking. Since this is the first time I have ever deviated from original equipment specs I wanted to confirm.

Go to 1010 tires and use their tools (or Google, lots out there) to see exactly what % you'll be off
