Hi, I'm looking to purchase some winter tires for my 13 Gen. My question is if I upped the sidewall from the stock 225 40 19/245 40 19 to 225 45 19/245 45 19, would it make the TCS go crazy ?
Gaijinn is correct. Staying near 2.5% is probably safe. Also the new tire sizes preserve the front-to-rear size ratio which means your TCS (which compares front-to-rear speed ratios) will function normally. Where you could possibly experience minor problems is the ABS function.The difference in your new setup is a -2.56% from front to rear. Thats under + or - 3 % so you will be fine.
