Need wheel and tire help guys and gals. I have a 2019 Bullitt that I just picked up with 19x9 & 19x9.5 wheels on there and I plan on picking up a dedicated set of winter wheels and tires as I will drive it all year round and I don't want to beat up the stock rims. There's a nice set of performance package. PP1 tires and wheels available locally with the same wheel size as the Bullitt but I know that doesn't mean it's a slam dunk that they will fit with no issues I don't know what the offset are on the Bullitt but the PP1 are as follows:

2019 PP1 - frontTire size: 255/40/19Wheel size: 19" x 9"Bolt pattern: 4.5"Offset: 45mmBackspacing: 6.7" 2019 PP1 - rearTire size: 275/40/19Wheel size: 19" x 9.5"Bolt pattern: 4.5"Offset: 52.5mmBackspacing: 7.3"

Am I overthinking it here? Will these PP1 tires transfer right over to the Bullitt with no issues? The plan is to keep high performance winter Pirelli's on the PP1 wheels and just swap back and forth instead of swapping tires every spring and winter. Thanks!

 

pretty much all of the OEM wheels within the same generation of car are interchangeable . . . so yeah they should fit

 

Thx Bert for the quick response. I'm grabbing them tomorrow. Question now is should I put 255s or 275s on the rear 9.5 wheel for the winter. Talking snow ice and constant sub 40 temps in the Northeast region. And which winter tires. I've read good things about the Pirelli Sottozero II tire.

 

for snow you want the narrowest tires possible, for me even 255 is too wide . . . check the tire specs to find the narrowest tire that is OK on those wheels, and size the aspect ratio to make the overall diameter what you need, usually around 27"

 

Thx Bert again. I'm going to look at multiple options for the rears. IF I went with 255s out back what should be the Treadwell size? 255/45/19 instead of 40 or would.it be reversed to 255/35/19. That always confuses me obviously this is on a 9.5 inch wheel. If I went even lower to a 245 what would that change the second # to. Again as always any help is appreciated guys and gals!

 

look up the tires in Tire Rack and you can see all of the information on the "specs" tab; including the tire diameter and the recommended wheel rim width range

you want to look at the tire diameter -- the outer diameter, which is the result of the wheel diameter, tread width, and aspect ratio . . . you want the diameter to be about the same as your original tires, which was 27.2" on most of these cars, or maybe a little bigger

the 35 or 45 number is the "aspect ratio" which is the sidewall height as a portion of the tread width, meaning a tire with the same tread width and a higher aspect ratio will have taller sidewalls and bigger overall diameter . . . you can play with this in combination with the tread width to get the diameter that you need

and sorry this is a little late, if you already bought those wheels, they really aren't the best for snow tires because they are too wide; ideally you would want the narrowest wheels that will clear your brakes, which I think is 9" . . . if you haven't actually bought those wheels yet, you might take another look for something narrower
