Oversized tires can cause havic on the vehicles performance mainly because the vehicles computer is expecting a certain speed of rotation coming from the front and rear wheels and when it doesn't see that it assumes there is something incorrect in the vehicles setup and will try to compensate until it can't. Once it can't compensate then it assumes that there is something broken on the vehicle even if there isn't and will set a warning light.
The difference in the rear tire size from stock to what he has now is .7% slower which would tell the computer that the front tires are moving faster on acceleration and could potentially result in a loss of traction. This is more than likely the cause of his issue."

There are other members that have this setup tho so i'm pretty sure there is a solution to this issue.
And everyone called me silly for sticking with 20's

But...I havent heard this issue from the other 21'er's, so not sure its really the cause here.
