Seriously man, your attempts at making yourself seem intelligent are backfiring big time. The garbage u post is either incorrect or just aimed to belittle people. Cool it already. How many times does Yax have to punk you for you to get it?

You're asking him to think a little?
The difference between going from a 225/45-18 and a 245/45-18 results in ONLY a2.7% difference in rolling circumference, NOWHERE NEAR the error he says he's seeing...
It also means that by going to a LARGER tire, the speedometer will actually read 2.7% SLOWER. When the speedometer reads 60mph, you're actually going 61.6mph.
Why don't YOU think before calling somebody else stupid?
I do realize he came back and said the tires were the stock size.

haha wait, what about my statement that 225/45 having a smaller diameter than 245/45 is incorrect? Let me know when you figure this out ok.

Brettus, it absolutely does make a difference what size tires you have.
Here's a handy calculator for it

Can't really comment as 09s have different ratios and top out even lower on each gear..

If you REALLY want to prove it, take it up to 9,000 RPM's in second gear, don't shift, and look down at the speedometer. You'll be going 65-66 MPH.
