I'm planning on going to 265 front on my next go around. Might be awhile for my front seem to wear slow. Even with track days and 2.3 camber. Steering might be heavier but for track use it will defiantly give better steer in being are cars are heavy in front. Another reason I'll be buying power sterring cooler.

I tracked my last car with these tires and Im not planing on getting anythiong else

So what were the db measurements between these and your old tires?

Since I am coming up on 15k miles on my RE-11s, time to heap some praise on. That's 15k miles, more than a dozen days of autocross, AND almost a dozen days on the track. I've driven 700 miles to VIR and been lapping on the same tires that months later would drive 800 miles to Homestead, right onto the track, and precede to embarrass slow Porsche Turbo drivers. With everything they have been put through I'd credit them for well more than 20k street miles.

My rears will need replacing soon, but even with the tread nearly gone they are still handling the constant NoVa rain right now. The fronts might get another 5k miles if I had some camber to play with in front.

+1 for RE-11s (265, 285 on Nismo)

How are the RE-11s in noise? I drive Bridgestone S04 Pole Positions which are VERY LOUD. Really need some quieter tires.

Better than OEM, but its not quiet

so i did the math on tire thickness which I assume would affect ride height. The second number (275/40/19) is thickness as a ratio to width right?

so stock 275/140/19 would be 110mm thickness
re-11 285/35/19 would be 99.75 mm thick

stock 245/40/19 = 98mm thickness
re-11 265/35/19 = 92.75mm thickness

which means I will be losing about .5cm F/1cm R in ride height, correct?

And if I was to go with stock sized fronts, I would just lose the height in the rear and not in the front. Will this uneven drop make any difference?

Just wanted to make sure I got it right also. My exhaust canisters barely scrape on my apt parking structure speed bumps after gettign springs. An even lower ride height has me worried now.

I think your math is off... my 285/35/19's are clearly a taller tire than the stock 275's.

is it? I thought it was 275 (tire width) 40 (ratio to tire with ie. 40% of 275) and 19 (wheel size)

I don't really know, trying to figure it out. Please let me know where my calculations are off.

There is a considerable amount of rounding that happens since profiles are only in 5% increments. The best bet to go by tire diameter on the specs page from tirerack or the manufacturer. Take diameter, subtract wheel size, divide by 2 and you have profile height (in inches).

I think I found my error. i was calculating the stock rears as 275/40 when they are actually 275/35, oops. sorry guys

there's actually a .4" height increase which will be great for my exhaust scraping problem, now if only my stockers would wear out faster

My RE11s at 15k
 

I've been very happy with mine. Looks like I'll get about 25k out of them with the outside fronts showing a little more wear than the rest of the tires. Increased my front pressure to compensate. At 15k they are about at the same noise level as the OEM tires were new. The PS2s I used to run on my 350 made less noise but it's hard to be objective because as we owners know our cars let a lot of road noise in the cabin.

I got these tires as a replacement of my stockers based on the recommendation of this site and they've turned out to be as good as the PS2s in terms of handling and wear. I never thought I'd say that another tire works as good for my driving habits as the PS2s but it's true, and cheaper to boot.

I used the stock size on the fronts but kicked up to a 285/35 in the rear to fill out the sport wheel a little bit. Bottom line, these tires definitely converted this long time Michelin guy.

After reading through the thread and really only seeing good things I decided to order a set of these today. I picked up my base model Z last week but decided to order some 19" wheels. Playing it safe with tire sizes and decided to just order the stock Nismo Z sizes. So I'll be running 245/45 fronts and 285/35 rears.

I feel like it's a crime but I doubt the car will ever see a track day, but I'm sure I'll still get to enjoy the extra grip around a few corners in my area.

I just ordered 285-35-19's for the rear today as well. Fronts still have a lot of thread left so I'll wait until the fall to get them... Hope the car drives ok...
