: 225/45R17 Autox Rub?
03-02-2005, 10:17 PM
Yes I searched this [;)] but not much pertained to racing. My mom got new tires on her BMW, so I got the old 225/45s off her car. I know they will fit the SVTF rim and won't rub under normal driving, but does anyone know if they will rub when the suspension is under load, e.g. autocrossing?

Nope, just stock here. Excellent, just saved myself lots of $$$ [:D] . Thanks!
What kind of tires are they?
The price was sure right![thumb]

Unless I'm mistaken don't bimmers have Continentals on them from the factory?

Yep, Continential ContiSport 1s, factory. Michelin Pilot Sports are optional. The Continentals are obviously not the best tire available for autocrossing, but as WD40 said, you can't beat the price! I plan on just using them up, then I'll get some racing compound somethings.
My stock Contis have been just fine on the course,
though dedicated R compound tires would provide some improvement.
One thing I've noticed, is the more these tires wear, the faster they are on the track.[thumb]

They WILL rub. I run Victoracers in this size and I get rubbing on just about every corner.....
You won't notice ( as I didn't ) until you really start to push the car, but they will indeed scrape a bit, though I have not seen any damage, and it only happens in really hard cornering. Eeven when I'm running my Koni's at full firm.....Time for stiffer springs, but I don't know if I want the stiffer ride on my daliy driver.
For example, in this pic, I was indeed rubbing, lol.....

Thats good news to hear WD40. I figured the tires wouldnt hold up to well on the track. I was just planning on shredding some free tires for a few runs. How long have you had your tires (miles/races)?
^^^12,000 miles, and 15 events^^^
Most of the events I ran 4 times, and a couple I ran 6 times.
About evenly split between a short course, ~50-55sec, and our road course here in Helena, ~1:40-1:50.
FWIW, they're getting close to the wear bars.
I'd guess I've got about 6,000 miles left at my current "usage" rate.
If I didn't use them on the track anymore, I'd guess that number would almost double.

I was looking at getting the new Falken Azeni RT-615, in 225/45 17 but I was worrying about rubbing because my winter tires do rub at that aspect ratio. How much of a problem is it in terms of unsettling the car and/or tire damage? It's no use to spend $700 on tires if they are going to bind and slow me down and/or wear out in a single season because they are rubbing all the time.
In fact I am also getting Konis as well, and I thought that that would solve the problem, but I guess not. I don't want to leave G Stock just yet, so I am not going to go to a stiffer spring. Are you still happy with the setup or would you go in another direction if you started again?
(BTW 225/45 17 Azenis are $145, 215/40 17 Azenis are $195!!!)

they will rub . but hell they r free so they will be ok they just will wear quickly fromt he rubbing

I love the Konis. Don't see any reason not to use 'em. and the tires only rub in HARD cornering. Other than that I don't get any.
The tires I use are V700 Victoracers, not Azenis. I've not noticed any unsettling of the car or any actual damage from the rubbing, on the tires or the body of the car.
Fact is though, the SVTF's tire size is really large for an oem setting on this kind of car, look at what Dodge did for the SRT-4...LOL.
I know some tires just don't come in our size, and that's a shame, but for what I use my tires for, I have no issues with 'em at all. if you can, or what you SHOULD do if you haven't already is take that 700 bucks and buy an extra set of stockers and then find some tires to burn out. Save the good ones for the street and use r compies or more purposeful street/racing tires for track day.

I probably would do that, but my Conti's are just about worn down completely, and I have my snow tires on right now. The Azenis really aren't all that much more than the Conti's and I need to have a new set of summer daily-driving tires that will also work well on track. From everything that I have heard, the Azenis will fit the bill. I probably will still get some Hoosiers or something like that later in the year, but I need a regular summer tire anyway...
I'm glad to hear that it's not a real problem. I was getting worried.
BTW, how much did you pay for your Konis?
