Will it fit?
I'm going to need new tires soon. I'll be buying Falken Fk452's. I want them as wide as I can fit 'em.
OE tire size is 235/45/17
Thanks!

they will fit, but the tread is too wide, leading to sidewall flex which means handling will suffer.

That's what I was afraid of.....
245's it is....

According to that calculator I should be fine....Originally Posted by BuckNaked
Seeing as I'm not tracking my car, just having fun in the canyons, I may have to give it a go....
Franka, a member here, has been running 275's on a 9in wide wheels for years now. He says he has no problems. If he can run 275's I should be able to run 255's....right?
Anyone else have some input? 255's all around sounds awful tempting...

It's physically possible(just like running 195's on an 8" wheel), but it's not going to be ideal for handling.According to that calculator I should be fine....

Minimum size per Falken website is 8.5" with 9" wheel recommended.

I recenly discovered that the STI and EVO guys have been running 255's on their OE 8in wide wheels for a while now without ill effect. I guess I'll be one of the first in the bimmer community to give it a try....

I absolutely don't recommend it. Go with a 235/40-17 for the best handling possible on your wheel setup.

Have you run this setup before?

+1. Trust us, 255 will feel mushy, unresponsive, vague. 235 will feel better and make transitions crisper. This advice comes from experience.
Dont think so? Here's a similar example. Check out the latest Grassroots tire test. They tested four 285mm tires and one 245mm tire on an 8" rim. The 245 was the fastest.

yea, on my 540i i run OE wheels with 245/45/17 Bridgestones on all four sides. No rubbing at all and even looks somewhat wide from the back.

No, and I never would, because I already know what I would be sacrificing.

i run a 275/40/17 on my 17x9.5's course this is on a Z28.. but a wheel is a wheel.. they fit perfectly with no "mushroom" effect.
having said that.. i have once ran a 255 on a 8" wide tire and the mushroom was terrible. Remember though.. certain tires run wider than others from different manufacturer's.. on a 8" wide wheel.. i would only use a 245.. for 9" i would use a 255.. for 9.5" a 275.. and a 10" a 275, 285 or 295.. depending on what brand tire.

dude don't do it. I have 255/40/17 on my 9.5 inch wide wheels. Your sidewalls are going to flex way too much. its just too much for an 8 inch wide wheel. I'm even thinking of going with 245s so I don't rub.
Member
If your quote showed 265mm vs 245mm I might see your point. But of course something as massive as 285mm isn't going to be right on a 8". He was asking if it would work to stretch the sidewall, not blow it out of the water.

Ok....
What if I was to use a tire that had a stiff sidewall? Maybe something like a Falken RT615...
Would this help?

no.. it wont..it will make mounting them a bitch for whom ever is going to do it.. it would actually make it worse because that stiff sidewall wants to be at vertical to the wheel and you;re trying to make it at a slight mushroom angle..
just dont do it.. learn from others that have already tried..

See that's the thing. The STI and EVO guys have tried with success. No one here has done this....
The tire width will be ~125% of the wheel width. I don't think the ballooning will be too bad...
We'll see...I'm still reading...

and you missed a key factor here... certain tires run wider than others.. find out what brand they are using.. and go from there..BFG tires typically run wider than other manufacturer's tires.. other brands are smaller and you might get away with it.. but you're also compairing apples to oranges.. you said STi guys and EVO guys.. their fender wells, brake systems, and backspacing also come into play for rubbing issues..See that's the thing.

how about this.. since you know STi people and EVO people are doing it.. have them post pictures so you can see it..

ok, if you run this setup your car won't explode, it just won't have crisp handling....and the tires will look a little like fat muscle car tires to those of us used to trying to maximize handling. It's your car, do what you want.

245/40/17's work well as a plus 0 setup on the stock sport 17x8 wheels.
Member
Since I am in the same identical situation (factory 17x8 wheels using OEM tire size 235/45R17), it looks like most favor using a tire even smaller than the factory setup for best, crisp handling: 235/40R17. So the order of preference for best handling, having the same tire size front/back, is then:
1) 235/40R17 (slightly smaller)
2) 235/45R17 (OEM size)
3) 245/45R17 (slightly larger)
Did I summarize this well? Wouldn't make sense to consider also a 245/40R17 size as well? Pros/cons?
Option 1 is preferred over the OEM for having slightly smaller/shorter sidewalls? Which is probably why option 3 is the least favored, right?

Looks to me that the author of this thread wants to get the wide tires despite the recommendation of all the posters here.
So let him make his own experience, blow unnecessary money for a tire way too wide for the rim and giving poor performance on top of it.
