I’m new to this website and I need help, I recently bought new tires for my coupe and I made the mistake in trying to make it staggered without researching more, I bought Pirelli Cinturato P7 all seasons. I bought 245/45R18 for the back tires and 225/45R18 for the front ones. The problem now is that when I reach a certain speed in the highway my AWD starts blinking slowly, what’s the best solution for this? Should I go back to all the same size?

 

Yes. I believe there are threads that address this question and you can go a tad larger but not much and IMHO it's not worth screwing up the AWD system.

 

Thanks, now I gotta sell the front tires to make them even
