Tire size

[coxfmly]

Hello,
I just purchased a set of new 3/4t chevy aluminum rims with tires.
The tire size is 245/75r16. I am currently running the stock tire size of 235/85r16 on my Sub. What issues if any will I have with the different tire size.

Thanks

Your new tires will be about 1" less in overall diameter than the ones you are replacing, 30.5", vs. 31.5", for a differance of only about 3% in actual speed vs. indicated speed.
