Just got the new tire installed on the rear and have it set at 26 PSI. Had a real nice grip to it! Not sure if you have the same sling as mine I have a 2016 base model. The front tires are 205 50 ZR 17. I know you can throw codes by messing with the tires but just wondering if anyone has gone larger or wider on the front tires and not made the computer go crazy. Any input would be greatly appreciated .
Glad you are happy with it! I have the SL, and it has 18 fronts and 20 rear. I planned to go up 20mm (width) in both front and rear next time I replaced them all. The second number is the percentage of the width for the sidewall height. There are many tire comparison places on the web. They will give you width, and diameter from one to the next. I planned to go up the same amount in diameter, to keep the nannys from getting ticked. But I believe ThomSS is running 22's all around, not sure the front to back size though. Mitch at RevDynamics set it up with his air ride. His speedometer is off though, pretty sure of that.
As for Federal, if I go with this tire I'll have to do stock again in size. The largest 20 they make in it is my stock rear size. That's OK, I think I can live with that.
