Staggered vs Square

[san]

I have 34psi on my 245/40 square. I tried 38psi but it was too harsh for MI roads.

I've read accounts of members having to use 34psi or less for more even tread wear, That's why I started, and I like the handling.

Ok I’m about to switch over to a square setup and deciding on tire size. I’m looking for some comfort and stability. From what I read on here 245/40 is a good option, but a staggered setup will offer better stability ?

What do you mean by stability? Adding front tire by going square will dial-out some of the factory understeer so that would create instability using your definition.

I have a coupe. When i bought it, previous owner had square setup (225 and 8in rim all around). I threw on some 235 all around and drove it like that for 4 years. A couple months ago I tracked down an original staggered setup, and TBH I much prefer the staggered. Yes the square setup was more neutral, even had a bit of oversteer, but it was also more prone to wandering on the highway. I have a 3.38 diff and found the rears would break loose easily (obviously not an issue if u do 255 all around). I can see the square beinng a benefit for tire rotation and for autocrossing, but having run both swtups, id choose staggered for its looks and overall stability. Considering much more powerful cars than ours (like the m3) still run 225 in the front, maybe we shuld consider throwing more rubber in the front may cause more issues than it solves (unless u never drive on a highway and ur commute is an autocross course)

I'm going with a square setup and after reading this informative article https://motoiq.com/how-to-properly-s...performance/4/
the best tire choice for my new square setup (apex arc8 18x8.5) is 235 40 18

Square setup on the ZHP is life. This was without question my favorite upgrade I did on my car.

What tire size are you running on yours?

I’m probably going with the new Michelin PS4S

I was planning to go with a square set-up with original 18x8.5 ET50 with 245/40R18. Will these fit on a stock 67k-mile suspension? Will 12 mm or 15 mm spacers be needed to clear suspension/bodywork?

245/40 up front is very similar to original 225/40 size, but wondered about the 245/40 rear tire size vs. 255/35 original.

Thanks!

235/40/18 is a nice size for the stock ZHP wheels on some wheel spacers.
