I have been using 20" Pirelli PZero tires on my 2015 QP SQ4. They are the low profile tires. I have blown out 3 in the last year due to pot holes or a curb hit. Any thoughts on not using low profile tires as far as handling etc.? Thank you

The problem is if you put larger tires on 20” wheels you will change more than you can imagine with the mechanics of the car. I remember seeing a QP some years back with huge wheels at my mechanics shop. Aside from the wheel well liners being torn up from rubbing the transmission was shot. A better solution would be go with smaller wheels with tires that match the current tire diameter.

You pretty much need to go with smaller diameter rims if you’re going to a with a larger sidewall. You “might” be able to upsize slightly but I’m not sure if that messes with anything else in the car or will even fit. You could find a tire with a tougher sidewall. I’m running Firestone Indy 500 tires and they’ve been awesome. Some of the reviews said they seemed to have stiffer sidewalls and that was one deciding point for me since roads are crappy around DC.

your best bet would be to size down wheels to 19" or even the 18" option from the factory/dealership. maybe source used wheels from ebay or a forum.
as mentioned, it is important to maintain the rolling diameter so as the speedometer, odometer, abs, traction control, transmission systems operate as they should.
scaling size with factory smaller wheels can be adjusted for via scan tool and a new configuration file from italy being loaded to the car.
