Here's my current set-up:



OEM 19" Sport Rays

Front: 19x9 255/40-19 Michelin Pilot Sport PS2 with 20mm spacer (= +27), -1.5 camber
Rear: 19x10 285/35-19 Michelin Pilot Sport PS2 with 25mm spacer (= +5), -1.2 camber.
TEIN coils (mild drop)
SPC rear camber arms/toe bolts.

What I'm going with:

Front:19x9 +20
Rear:19x10.5 +25

My questions:

1) I already purchased a set of Michelin Pilot Sport PS2 305/30-19 for the rear. I'm thinking a 15 or 20mm spacer added?

2) What about fronts? I was thinking either 255/35-19 or 265/35-19? Getyourwheels.com stated to use the 255 because it would "look" better. I also don't think I'll need a spacer for the front?

Suggestions & opinions welcome

15mm spacer in the rear and at most a 5mm spacer up front but you may not need it at all. I would run a 255 just because it sits better on the 9" wheel then then 265.

Being 50mm smaller than the rear, wouldn't I experience some understeer?

You would probably get under steer even with a 265 but turn in response will be better with the 255 also. A 275 or 285 would be best to match with your 305 rears but the rim width is your limit. You COULD still fit a 275 on the front but then turn in response will decrease and it'll feel sloppy.

I would like some more opinions because one issue I have is also the look of the sidewalls. I currently have 255's on my 9" rim and it looks a bit stretched. I know the 305 on the 10.5" will have a bit of a bulge. My thinking is the 265 will have about the same amount of bulge vs. a stretch due to the 265 & 305 section width are both about 1.5" over rim width. Also, with the 255, it would have a smaller diameter and sidewall compared to the rear. OEM has fronts a bit larger so the 265 by the numbers is a better fit:

......................255/35R19...........265/35R19.....305/30R19
Section Width: .. 10.04 in .............10.43 in .......12.01 in
Rim Width Range: . 8.5 - 10 in.........9 - 10.5 in....10.5 - 11.5 in
Overall Diameter: . 26.03 in ............26.30 in ......26.20 in
Sidewall Height:.. 3.51 in ...............3.65 in .........3.60 in
Radius:...............13.01 in..............13.15 in .......13.10 in
Circumference:.....81.77 in..............82.63 in.........82.32 in
Revs per Mile:......799.15/mi............790.78/mi.......793.75/mi
Actual Speed:......60.53 mph...........61.18 mph......60.63 mph
Speed Variance:...2.65% too fast....1.57% too fast..2.48% too fast
