Default Can 235/40/18 fit on the front?

My car needed front set of tires soon. I wanted the front tires to match better with the back. Can I run this setup for the front WITHOUT any problem like odometer, rubbing or any censor? Please post pictures if you have this setup. BTW my car with stock 18" stock.
Thanks in advance....

This is mine with a 10mm ichiba spacer. I am running 255/40/18 rear with a 15mm spacer.



The sidewall buldge matches the rear perfectly. I think it looks perfect because the buldge is identical, but the diameter is a smidge smaller up front. I think it should have come like this from the factory. It also helps eliminate most if not all of the understeer.

I'm curios about what are the differences to run 225 and 255? I know as tire goes wider it distribute the weight thus increase the tire life, so in the contrast as tire goes narrower it increase the tire traction, correct me if i'm wrong, but what are other pros and cons?

I actually just put 235-40-18 tires on the front after months of contemplation and warnings that it will rub. All I can say is that it should have come from the factory that way. The Ride is sooooo much smoother, and it fills the wheel well up better to match the rears. I put Vredesteins on and have no rub at all.

Two things to keep in mind:
1. Make sure you get an alignment after
2. Not all tires are the same size and may cause rubbing, watch out for tires with a very square shoulder and ones with a very deep bead protector.


I will try to snaps some pics later today.
