Tire/Fender Rubbing Question

[Mazdaspeed3KHP]

Hello,

I'm trying to decide whether a 235/40/18 has more fender clearance or a 245/35/18 has a less likely chance of rubbing.

I've decided on a set of wheels that are 18x9.5 +38. Now to fit this on a 2012; I'm wanting to go with the 245/35 series but if a 235/40 series is going to rub less then ill deal with the stretch.

The tire calculator points to the 245/35 being smaller in every area except width. Would the smaller height give me a better advantage of fitting these wheels?

I ran 18x9 +35 with 245/35/18's in the past with no issues so I'm leaning towards the 245/35's.

A second example that I've ran on this car are Evo x wheels 18x8.5 +38 with 245/40's. These had more rubbing issues than my 18x9 +35 with 245/35's. But I've never tried any wheels with 235/40 so that's my long lost question.

Which works best? Rear fenders are rolled and bumper tabs are shaved off. I'm lowered on Sonic tuning coilovers but its more of a spring drop height. Front camber is -1.4 and rear is -2.3.

Thanks

235/40 will not rub, I was going to order that exact size but ended up finding a better deal on smaller tires. Even lowered I don't think it'll be an issue.
245/45 would not fit on my stock car (rubbing)

So just go for 235/40

Well maybe if you did your research you wouldn't be asking this question for the 1,000th time its been asked on this lame forum buddy. LOTS of tire fitment threads have been posted.
