car freaking out after tire change
#22
Minimize aggravation and you'll live longer and be happier.
Put new 305/30/20 tires back on the rear, and ask your tire dealer to take the 305/35/20's back. After all, it their fault for letting you put the wrong size tires on your car.
If they won't take them back, dispute that charge with your credit card company in writing (assuming you paid for the tires with a credit card). Wait for a resolution from your CC company before you put the 305/35/20's up for sale on eBay, since they may require you to return those tires to your tire dealer.
Good luck, and let us know how you resolved this issue.

There is a many things wrong with running the wrong diameter.
False readings
Increased miles on odometer
Slower speeds
More weight
Possible fender damage on severe bumps
Inaccurate **** points.
The only upshot is a smoother ride, higher top speed and less possibility of bent wheels.

You're very funny, and thanks for bringing back memories. The first time I heard that line was when I was 5 years old and she wanted to play doctor.
I don't have to show you anything because I'm not the one who is suspected of being a troll. And I'm not the only Forum member who is suspicious of you and why you're here. If you want to see photos of my XKR and XJ, I've already posted lots of them in multiple threads on this Forum.
You have zero credibility on this Forum until you prove that you're not a troll by posting pictures that verify that you own a 2014 XKR-S GT in Pennsylvania. Prove that I'm wrong and I'll apologize. Until then, I'm done playing your game and this is the last reply you'll get from me.

Maybe someone else here can comment- I believe you have a failing battery if you only have 12v

I will add that I'm 5% taller front and rear with no codes so I guess it needs to see speed inputs farther outside the norm front to rear.

Ok folks here is what I have done. Put battery on charge. Once charged took car for a spin and the sensors started flashing again once I hit @ 35mph. Just put on the new tires on the front. Took it out and the car is fine. No sensors flashing at all. I am relieved. To cap off what I did- stock tires - front 255/35/20. Rear 305/30/20. I used the stock wheels. 9/20 fronts and 12/20 rear.
I put a 305/35/20 drag radial on rear with the stock fronts. This made the circumference difference around 5.0% according to a tire size comparison chart that I used. I then put a 255/40/20 on the front. This difference with the 305/35/20 is 1.4% using the chart.
New tire combo - front 255/40/20. Rear 305/35/20.
Thx goes out to everyone that posted an opinion / idea. I couldn't have figured this out without ya. Next to do what s a tune I think.

I would also love to see the OP's car int he light from a couple different angles. Honking big arsed wing has some advantages.

OP - have you noticed it blunting the acceleration any?
I did similar on my old Boxster, in error, and ended up with too large circumference tyres on the rear. I'm sure it made the car slower to accelerate.
Maybe not so noticeable on an XKR mind!
