The guys mounting them struggled a little with the oem sport rays but they got perfectly. I think I posted pics a few pages back

I dont have sport rays.... I have TE.6 wheels

You are measuring inches where I am comparing millimeters (more precise).

I scrapped the 265/35 tires and opted for 255/35 instead. The front tires are still slightly taller than the rear, but visually hard to discern.

IMO- the front 265/35 was visibly taller than the 295/30 rear. A difference I couldn't live with...

The 305/30 is 91.5 mm and the 265/35 is 92.75 mm with a difference of 1.25 mm.
The 295/30 is 88.5 mm and the 255/35 89.25 mm with a difference of .75 mm.

i have had 0 issues with 265s up front.

I agree you shouldn't have any issues at all. For me, the difference in tire height is too much. I chose tires that look closer in height front to rear.

offsets then. i'm on stock sport rays with my 265/305 set-up

Hey guys, I know this may have been asked already but there's a ton of info here to sort through: Will I lose height going from 245/40 to 265/35 fronts and 285/35 to 305/30 rears?

most liekly. its tire specific to. go on tire rack and compare the overall diameters of the tires and sizes you are looking at

Taylortoons · 04-25-2014, 03:45 PM

The same calculation can be used for any tire. Multiply the tire width (245) by the profile (.40) to get the mm height.

EX. 245 x .40 = 98 mm, 265 x .35 = 92.75 mm

The answer is yes, you would lose height going from a 245/40 to a 265/35

The offset doesn't matter since you are calculating the width/height of the wheel/tire combo. The offset comes into play whenever you start thinking about how you want them to fit under your fenders and potentially clear BBKs.

JaviZ · 04-25-2014, 04:59 PM

Taylortoons, thank you!!

So if I don't want to lose height because I plan on keeping the stock Nismo suspension, can I go 265/40/19 front and 305/35/19 rear with spacers all around? Haven't seen a writeup on this size yet. Most common set up is 265/35 and 305/30 with some sort of drop.

265 x .40 = 106 mm, 8mm higher than stock in front. 305 x .35 = 106.75 mm, 7mm higher than stock in the rear. Just don't know if I'll have any rubbing issues.

Those are huge! Maybe there is a good reason no one is running that setup.
