Hey folks question for the 18x9.5 TE37 owners, what sizing tires are you running?

I would suggest going thru this thread: https://www.m3post.com/forums/showthread.php?t=486694

But most people run a 265/35/18 on the 18x9.5 ET22 TE37SL.

275/35/18 if you are looking to max out the tire size. 265/35 is much smaller overall wheel diameter compared to stock.

The minimum and maximum recommended tire width for a 9.5 wheel is 245 and 275, with 255 and 265 being ideal.

265/35/18 square will you want the ability to rotate tires and reduce some of the understeery characteristics of the car. Wider front tires have also been known to increase tramlining although this is more dependent on tire compound and alignment.

Or you could do a 255/275 stagger or 265/275 if you like the staggered look. Even oem sizes would work but the front would look a little stretched.

Any increase or decrease in tire diameter will change the overall effective gear ratio. A smaller tire will travel less per rotation than a larger one. thus the speedometer will read slighty higher and the odometer will read slightly higher. A bigger tire would have the opposite effect. Top speed for every gear will also slightly change. Just something to keep in mind.
