So did you buy an extra set of 18x8.5 for the fronts?

 

I got the PS A/S Plus's installed this morning. Huge differences in this tire in comparison to the F1's. They are significantly quieter and more comfortable than the F1's. Going over a set of railroad tracks the F1's would come loose, the Pilot Sports keep the car planted. I've only driven 10 miles on them so it will take some time for a more in depth review.

 

There's another A/S option available... Toyo Proxes 4
They're available in the stock 18" size - 225/50/18 and 245/45/18
I had them installed on my G35S last month. Smooth quiet ride, but not quite as sticky as the original RE050As.

 

I had the Proxes 4 on my Maxima and didn't like them at all. They were great in the snow and great in the rain, but provided little road feel and poor dry performance. I loved the Falken Ziex 512's the Toyo's replaced, but the Falken's didn't last very long before their wet performance decreased.

 

To All,

This is a follow-up to my last post regarding the issues I am having with the Goodyear Eagle F1's.

Before I splurged on a new set of tires (due to the excessive noise), my car was due for service anyway, so in addition to the 40K service I had them do a 4-Wheel Alignment. Apparently, the alignment was off (so they claim), but since then the noise level from the tires has been reduced to a tolerable level.

The dealer also told me that I had approximately 7/32" of tread left on the front tires, and 6/32" in the Rear. But they also told me that my front tires were cupped which are causing the noise, hence my current dilemma.

Given that the noise level has been reduced, I am hoping with the alignment, that the tires will wear more evenly over the next 10,000 miles or so. After that I am planning on replacing all four. (probably sometime in late summer or early fall).

Is there any problem with running with cupped tires? Will the uneven wear cause any additional alignment or suspension issues?

As I stated in my earlier post, when I do replace my tires I would opt for the Michelin Pilot Sport A/S Plus in 235-50/18 and 255-45/18, respectively. I know that some of you have already done this with no problems, but my car also has 4-Wheel Active Steering. I am wondering if the larger tire size in the back would cause problems with the 4WAS?

I just wanted to share my thoughts. Anyone have any input?

Regards,

 

I have been waiting to hear if anyone has done this setup 245/45/18 all the way around. Thanks for posting! Does it look any different? I just ordered the Eibach prokit and wonder if ilowering it with your setup will have any negative affect.

 

245/45/18 all around works ok

 

To All,

I just got off the phone with the Tire Rack. The salesperson I spoke to recommended that I opt for 245/45-18 in the front and 275/40-18 in the Rear. He further explained that the respective diameters of these tires would be almost the same as the OEM sizes:

OEM: 225/50-18 - 26.8"; 245/45-18 - 26.7"
Optional: 245/45-18 - 26.7; 275/40-18 - 26.6"

He further went on to explain that the 235/50-18 and 255/45-18 (the sizes I asked about in an earlier post in this thread) would have diameters of 27.3" and 27.0", respectively.

Has anyone opted for the 245/45-18 (F), and 275/40-18 (R)? I would be interested in the pros/cons, and you overall impressions.

Either way, I will be replacing my Goodyear Eagle F1's (the noise is driving me nuts) in the next month or so. I may even go back to the OEM Bridgestones if I decide to stick with the OEM sizes.

But what I really want are Michelin Pilot Sport A/S Plus' which everyone knows are not offered in the 225/50-18 size.

Lastly, I have 4-Wheel Active Steer on my G. Any potential issues with this system as a result of changing tire sizes?

Your feedback would be appreciated.

Regards,

 

On my second set of BFG GForce A/S. 245/45/18 back and 255/45/18 back. Very competent tires, wear a little better than the stock Potenzas, not quite as sticky but almost as good on dry roads/summer. Get about 20k from a set (got 15k from the stocks). About 3/4 the cost of the RE050As. Summer tires are not so practical where I live so willing to give up a little summer grip for those Oct/Nov frost-covered roads before the snow tires go on.

 

Never knew 275 wide tire can fit on a 8.5" rim. That's news to me. I thought the miminum you can fit a 275 on is 9"

 

You are correct. I am going to go with the 235/50-18 for the front, and 255/45-18 in the rear.

Thanks again to all.
