Did a search did not come up with a POSITIVE answer...

Was thinking about going 225/40/18 and a 275/30/19...What is the biggest tire I can run on then factory OEM NA rims without having rubbing or clearence issues..ordering a new set and wanted to go bigger. Can the front be bigger than 225/40?

 

Ok after searching...which I got a LOT of different answers

Comfortable ride...235/40 in the front
275/35 in the rear

Not so comfortable 275/30 in the rear.

Live in East TN so not that much bad weather...some of the backroads you might see a pothole or two, but I drive mostly main Interstates and 4 lane's..

 

Hey folks ,
Akers04Coupe (Jason) sent me a PM asking me for some answers here but I am unable to answer his questions.
Can any of you out there post any useful info for him here ??

Thanks for your help guys

 

It's always a good option to check with Tirerack.

 

I don't know why more folks don't use this great tool:

http://www.rims-n-tires.com/rt_specs.jsp

It answers all of these questions! And it does it with pictures!

In front, the biggest problem is clearing the upper ball joint nut.

And in the rear, if you get too close to the inner tire well, you will rub it if you hit a large bump. But the OEM sizes do that.

 

Thanks Max. I'll sticky this.

 

FP, great move! I f you allow, I can add to this info on spacers and stuff, unless there is enough info allready?

 

Max,
I have this link saved but didn't think it would indicate the limits for clearance issues for our particular cars.

 

It doesnt Val, thats my point here. Thats why I was hoping somebody on the forum had tried to go bigger with a stock suspension and wheels

I KNOW somebody has... that site mostly shows UPGRADED wheel and tire packages. I was just in such a hurry because I was gonna order 2 sets of tires 1 set for the X-Fire and a set for my Wife's 540i.. Tire rack BTW DID NOT KNOW the answer either...I think I am just gonna go 275/35 R and 225/40 front...I wanted a 235/40 to get a little more rim protection on the sidewall. But I am afraid of clearence problems. Thanks VAL for sticking this!

 

You're both right, it doesn't show any more than the changes from OEM. You would have to figure out the rest.

This is what I have in mind...

$643.34 to the door WITH ROAD HAZARD

235/40s FRONT
275/35s REAR

320 Treadrating, which I ok with hows this look?

 

Nice, popular tire. Are you putting them on stock rims?

 

I can tell you right now that I have the Khumo 18s you're talking about on the front of my car with aftermarket rims. The offset is 22 I think. Anyway, there is some rubbing when turning the car - the outside of the tire rubs on the wheel well noise suppressor (the plastic-like shroud that is directly behind the wheel in the wheel well). I've driven them about 5K and I don't believe it's wearing them down. Just thought you would want to know. I'd also like to hear how the 275s work.

Note that the Khumos are louder than the Michelin tires, handle better in snow, but slip a little more in summer driving. IMO.

 

Hi, This is off of the rims-n-tires.com site.

I went up one aspect ratio front & rear.
I've had zero problems with the rear.
The only problem on the front is that on full-lock the tire rubs the inner plastic fender/cover at the front. When the wheels are turned right the left wheel rubs at the front - I think when I'm going both forward & reverse.
I am nut using spaces, but I imagine spacers would make the rubbing worse as the wheel would be further out/forward when on full-lock as described above. Plenty of clearance at the top to the threaded stub/bolt on the suspension piece.

 

YES Stock NA Rims

Thank you for the reply's, so my theory is OK to go to 235 FRONT and 275 rear. I have been debating and just feel like I need a little more wheel protection up front with the 235's and WANT more meat on the back with the 275's.

 

GLAD to hear this, I am not worried about the turning aspect, only the hitting the suspension on bumps aspect..

 

235/40 Front's NEXXEN' N 3000's
275/30 Rear's
$518 SHIPPED to the door.

340 treadrating too...my Hankooks have a 280 treadrating

 

Same size and brand tires on my car...I love the Nexxen's and they have a great looking tread!

 

I've seen 285/30ZR19s on stock rear wheels before... seemed to work fine. I just put 275/35 on the rear of mine, not issues so far, but I've only driven it a few miles.
