30" To 31" Tires

My new (used) tires should be here tomorrow, I will get them installed Thursday or Friday. Do I need to worry about changing the speedo gear? Thanks, Scooby

did it come stock w/ 30's? i don't think you'll notice much difference. if it came stock w/ 205/75r15 or something, you'll notice a little difference.

"The danger to America is not Barack Obama but a citizenry capable of entrusting a man like him with the Presidency. It will be far easier to limit and undo the follies of an Obama presidency than to restore the necessary common sense and good judgment to a depraved electorate willing to have such a man for their president."

Speedo shouldn't be off but a couple MPH. I wouldn't worry about it with that little difference in tire size. But that's just me.

with my 31's the speedo is off about 10mph lower than normal when driving on the highway, as for driving on the streets its not off by too much.

maybe worry about a little rub, that's it. I have 31's and a 2" Lift and it rubs when I lock out the wheel... no big deal.

your speedo will be 3% off so when the speedo reads 100 mph you will really be going 103 lol. At 30 mph you'll be going about 31.. barely any difference. (30s vs 31s)

I had the 30s stack on my sport and I upgraded to the 31s. I have absolutely no problem with tire rub, and I dont have any aftermarket lift kits. And the speedometer doesnt show much of a noticeable difference at all.
