Should I go with 245 front and 275 rear or...?

[BTEMY]

Hello Gang,

I'm currently running 19" SSR with 245 on the front and 275 in the back.

I'm going to be purchasing 18" OZ Alleggerita HLT for weight savings. I also got tired of repairing my 19" SSRs every few month from the put holes we got all over San Francisco.

I'll be going with Hankook Ventus V12 tires. The suggested sizes, naturally are

225/40ZR18 XL front
265/35ZR18 XL back.

The quesitons, should I go with 245 for the front and 275 for the back like I have done with my 19"?

thank you in advance.

Here is how the car looks right now
