265/35/18 - will they fit?

[2subyfamily]

I got an amazing deal on some winter tires that I'm hoping will fit the B9. They're 265/35/18, I see others using the same size but in 17's... can anyone help?:confused:
EDIT: 235/65/18's

I don't see why they wouldn't fit. They will just be slightly wider on the rim and the profile will be a lot less... 35's!!! thats a low low profile. I am not sure of the calculations, but it may throw off your speedo slightly.

That definately sounds like an ultra high performance snow tire. Which brand? and how much are you paying?

On 17" steels I have 235/65/17's I don't think anyone is running 265/35/17's.

:o :o :o
oopsss...
reversed the numbers... typing away without looking they are 235/65/18's.
And I even typed it twice without noticing. can a mod edit the title to correct?

They should fit the rim, they may look a little small width wise, and
the overall height may be taller. Your best bet would be to check with
a tire retailer.

I wouldn't do it. Your speedo will be way off. I use the above website when looking for other than oem sizes for tires.

Thanks.:D
I'm off by 3.4% - the speed will be showing too slow.
Is there a generally accepted range?

I've allways heard that you should not go over 2% difference.

Eh, I wouldn't bother if it throws off the speedo that much. I'm no engineer, but would prolonged exposure to the improper radius affect the drive train or steering in any way?

I'm gonna sell the tires... I've been looking for a set of winter rims for a while and found a set from a nissan 350z which are 18x8, 5x114.3 and 30mm offset - they're curbed a bit so are cheap.
How does the offset work?

I dont see an issue with the speedo being off affecting any drive train or steering either. Outside of inaccuracy, I dont foresee an issue.
