Picked up some coupe 19's 4-19x8.5 and am looking at tires now. Should I go 255/35 or 245/40? Need some opinions.

Dropped on z/g springs.

255 on the rear, 245 on the front (if you want it staggard).
You won't be able to rotate the wheels if you keep the tires the same size so either way.

did you buy these off PreacherMan at my350z?

No, I've had these for a few months...

Thanks Ryan, but they're not staggered wheels so why run a staggered set-up?

Coupe 19's are 19x8 in front and 19x8.5 in the back.

I have 245/40's all around dropped on Tein H techs and when I replace the rears I'm going 255/40. The 255/40's are closer to the same diameter as the 245's than 255/35. The 35 series profile leaves too much wheel gap for me.

I'm also on coupe 19's.

Yes... but I have 4 coupe rears...

Even the 245/40's are bigger in diameter than the OEM 215/55/17's. 255/40 will be even bigger than OEM.

Ahh I see.....

I'm running 245/40/19's for 4 years now and dropped on Z/coupe springs and love the look & ride...helps fill up the fenders a tad more w/ less of a gap.

I did! (Is that a bad thing?)

I was curious about this exact question, glad I stumbled on this thread. Does anyone have spacer recommendations to fit flush with the fenders when you have 8.5s on all 4 corners?

No spacers needed. When I test fit mine they were flush.

Oh! I didn't catch the 4-rears part.

Well then it comes down to this:

Which will sit flush and not rub, if both then-

Which tire size is cheaper to purchase when comparing the same brand.

If you can fit 255's then I'd recommend 255's, worst case you may need a moderate fender rolling in the rear but I think you will enjoy the look of the wider tires (even though 245 and 255 is minimal).

Thanks again!
