Tires sizes

[AdamG]

I am currently tire shopping...

the door sticker says to use 235 75 16

I bought the truck used and it has 245 75 16 that are now bald.

While shopping at Walmart, Costco and a few other web sites, it says that the truck can use 255 70 16 and well as what the sticker said.

 

This doesnt make sense.

wouldnt the 255 70 16 tires throw off the speedometer?

Those tires have the same diameter so speed will indicate properly. They are all 75 series tires. Change series and you get a different speed on the speedo. Go from 75 to 50 for example and speedo will indicate a faster speed than you are traveling.
