Question
Any thoughts on running a smaller sidewall on the front?
- I.E. 245/40/18
...if I keep the rear size: 275/40/18

Details
This is without TPMS.
These will be track tires.
I am leaning towards Nitto NT-05

youll want to compare load rating... and why nitto's.

Nobody makes a decent tire with the two sizes listed below, besides PSS, and those are too much for a Track Tire.

- OEM Front spec: 245/45/18
- OEM Rear spec: 275/40/18

i thought OEM Z base wheels (the 18s) came with 225/245 setup?

i know sport packages OEM Rays have 245/40/19 and 275/35/19 tires

Run the 245/40/18 and 275/35/18. Problem solved.

Is 1/2 inch less sidewall something to be considerate of when tracking ur car?
- These are track tires btw...

Only if you are on coilovers and already sitting low then the lower tire height would become more of a concern.

I run 35 profile tires on all 4 corners.
