Max tire size

What is the max tire size I can put on my coupe to achieve little flush and bulky stance?

currently on Factory staggered setup:Front 19"x8.5" - 225/45/19

Rear 19"x9" - 245/40/19

Fat tires aren't going to get you where you want to go, and with bulging sidewall your handling will be compromised. Get some wheel spacers instead... although at OEM ride height, adding a little poke could look more awkward than otherwise.

I was thinking of wheel spacer but got negative feedback from the mechanic

Installed properly and torqued down correctly, spacers are fine. You wouldn't need more than 15mm anyway.

Sorry for the potato quality - havent seen the sun for the past 3 days- that and all the rain and debris thanks to TS Ophelia.
Anyway, stock square setup 19X8.5 with 245-40's, 15mm SPC (I think) spacers on BC colovers with a ~2 inch drop. Its a little tucked in the rear, 20mm would probably look better, but i dont plan to pursue that.

thank you for your share, really appreciate it. So 15mm front and 18mm rear would do the job with a spring drop.

lastly, what kinda drive issues you had or felt after adding the spacers? 🙏

I have the sport package too of course and I use 15 mm spacers in the rear and it sits almost flush. 20 MIGHT stick out just enough to sling dirt and debris on your rear bumper. Had 15 mm on the front but took them off because the front tires did sling dirt and debris onto the side of the car, the added vibrations even through they were hub centric, and it made the steering heavier. But it did look good though.

This is going off the Tire and Rim Association / European Technical Tire and Rim Organization

widest tire for a 8.5" wheel that's at or close to oem diameter is 255/40R19 at 27' diameter

widest tire for 9.0" wheel that's at or close to oem diameter is 275/35r19 at 26.6" diameter

the best combination is 245/40R19 and 275/35R19 as those diameters match. you'll still want to run a spacer up front if you want it to be flush at the fender as everyone is mentioning.

Awesome! 😊 thanks for sharing and add this to our knowledge.

What would be the issues and concern, drive and feel, brakes issues or rubbing on full turns I would face or live with it by running the best combination of 245/40R19 and 275/35R19
