Will Kumho ecsta le sport 265/35/18 fit on 01 330ci sport package?

I have 9.5 by 18 vmr 710s for my rear.I really want to put 265 in the rear but I dont want to roll my fenders at all. I have the stock sport suspension. Will this tire size fit?

What is the existing tire package, and how much room is there from the tire to the fender?

If the proposed tire package dimensions fit within the space your currently have, then yes. If not, then no.

A 265/35 is more than an inch bigger around than a 225/40, which is the standard fitment. It's also an inch wider.

If you have the same or lower ET on the new wheels and they are wider than the old wheels, then they will be pushed outboard toward the fenders. If you have an inch from whatever you have now to the fenders, and the new wheels are the same ET but an inch wider, then you have a tight fit and will probably need to roll your fenders a bit to get some clearance. If the new wheels arfe wider and have a lower ET, then your proposal will definitely require rolling fenders.

You need to know what you have and how much space there is, then you can do the math to figure out if the new plan is a good one or not. Me thinks, not.

YES,
since no one answered my post about whats the largest tires that can fit on e46,
I did my own seasearch and found out that

the biggest tires you can put are offset ET35 in front on 19inches and 8.5 wide, and offset ET45 in the rear on 19inches and 9.5 wide,

from there the tires could be 225/35 in the front and 265/30 in the rear,

this is on a normal non m coupe, for sedans its smaller.
no fender mods.

so yes the 18 inches will only fit if your offset is not bigger than what I said
ET35 in front and ET45 in the rear
265 max tire size no fender mods

im not sure about this but you can see how the offset on the front tire ET35 is bigger and the tires is less wide 8.5 compare to a smaller offset of ET45 and larger wheel 9.5

both the front and the rear are the same size sort of because of different offsets and width in different directions

if I have to take a guess the 10 that's between ET35 and ET45 is equal to the 1 inch difference of 8.5 front and 9.5 rear

which makes both look the same size, but be different in functionality
1 is front and 1 is rear but they both look the same when they are mounted on the car

Yeah I get you, my rims are 45 offset so it will sit very tight with the tires on but it shouldn't rub if it does rub then it will be very light. I've seen guys put 10 in wide rims but im not familiar with how they do that. Im guessing they have higher offsets??
And I currently have 235 40 18 on front with 8.5 rims. I think 265 35 18 will match perfectly with ones upfront but I also heard stories of the tires rubbing in the back over bumps or when theirs passengers.

You won't have any rubbing at all with those tires

Do u have 8.5 wide in front and 9.5 wide in the back ?

For driving its better to have staggered tires only if your mags are also staggered, less wide in front and wider in the back.
I think for good driving if you want to have 265/35 in the rear you would need to put 245/30 in front.
But if you don't care about performance much than sure you can put 235/40 in front 8.5wide, you can put 225/35-19 8.5wide so 235/40-18 should be approximately the same size.
With 8.5 in front you can have a bigger offset than ET45 I'm guessing your front wheels are ET35 already.

^^I mean 245/40 in front not 245/30

But to put those would be impossible, so that's why it's not suggested to put 265 in the back but it's not a huge problem if you don't take curves very fast

Yeah I have 8.5 front and 9.5 rear.
Hmm i believe 225 would be the best choice upfront over 245. Bigger tires upfront follow the grooves on the road and its a pain. I have the happy medium of 235. I do love turning hard! Right now I have a track set up of 235 all around. I love the way the car handles with this setup but now i want more beef in the rear. So I will lose some performance.

OP - If you're running 18x9.5 ET45 size on your coupe, you can run a 265/35/18 tire without an issue.

Are you sure? I asked a guy from mod bargains and he said it will rub when turning hard or with passengers, but the rubbing will be very minor.
Im getting mixed reviews

Those are our recommended wheel and tire specs. You won't have an issue on stock suspension.

Oh btw my right rear shock is leaking slightly. Will that be a rubbing issue?

As long as your alignment is good, I still don't think you'll rub. The spring is there to support the car, so you'll just notice more travel with a leaking/blown shock most likely. Definitely replace that shock though when you can! There are vendors on here that sell replacement suspension, I'm sure!

Do you think performance wise it's worth getting 265. Would 255 be better? Including grocery shopping and carrying 3 passengers in the back? I still want my car to be reliable. Zhp comes with 255 I believe and the fenders are the same as my car.

For everyday driving, you will likely not notice a difference between 255s and 265s. If grip and power are a concern though, a 265 will provide more of it. One thing to consider is that the tire compound will make a huge difference. Some 255s will outperform other 265s. If you're looking at a 255 Michelin Pilot Super Sport to a 265 Hankook Ventus V12, I'm confident the Michelins will outperform the Hankooks.

Tires just came in. Here is how they look. Btw I realized that I made a mistake on the name of the tires. They're Kumho Ecsta spt. They're actually pretty light too.
