the 245/40-19 diameter is 26.8". 275/35-19 are 26.5". 285/35-19 are 26.9". the speedometer would actually read more accurate with the 285 because cars tend to come from the factory reading ~2mph fast.

the reason why you feel that way about the re760 is because it is an UHP tire vs the S04/re050a being max performance, which is a higher grade. also the re760 wet performance rating isn't as high as the s04 (http://www.tirerack.com/tires/tires....za+RE760+Sport). i'd advice against the conti dw since they have notorious for having soft sidewall = sloppy handling.

Well I had to compromise alil with performance for better mileage from a tire. I didn't think it would be a dramatic difference but it was. Also there were like only 5 reviews for the re760 at the time I bought em. Just goes to show the superiority of the s04

Also to correct my last post i was only getting 10k miles or less from the rear tires. Which is in line from this sorta tire.

So the S-04s don't last long? Shouldn't they last longer than stock RE050s?

I found that they lasted longer than the RE050A, but only marginally. Better grip and response, though.

yep, wat alstann said. have to remember these are summer tires. im good if i can get over 8K miles on them.

the amount of driving i do, i dont mind the shorter life cause it's either motoring fun, or dry rotting :ugh: i prefer motoring fun. :D

if you want longer life, i suggest you get the DW's. those wear well. but you do loose some wet weather grip and the steering feedback.

Well, I got 28k miles from the stock tires. The Z is mostly a spirited DD for me. If I can get 25k miles with the S-04s I'm fine.

I just ordered a set of 4 stock sized S04s for $804 via tirerack. 245 front and 275 rears. And it comes with a $50 off coupon so its $754. Shipping and mounting/balancing are extra but still quite the deal!

Waiting on tax time but I'm going to jump on these as well.

Looks like I'll have to fight for the $50 rebate since bridgestone and tirerack took down the webpages to get the promo code and submit the rebate. Rather stupid as the offer stated tires purchased from like mid Nov through midnight Dec 31 qualified but then on Jan 1 they take the sites down to get the rebate submitted. :-(

Couldn't wait on tax time so jumped on these through tirerack. Got them in stock size for $864 shipped to my door. Really digging the wide rain channels on them and can't wait to have them mounted. :happydance:

I bought the s04 a few years ago for my g35 coupe. I was absolutely extremely impressed with them. Just got a 370z and am now thinking if these or pss to replace stock.

What is the speed rating on S-04?

"Y"

I will be putting a set of these on my Z this weekend. How has the tread life been on these tires so far for this who have posted in the last year?

So far 6k miles seem to be doing well.

I had these installed on Friday of last week. Tires have a lot of grip but not quite as good as the OEM yokohama advans. Road noise has reduced as well. Impressed so far and will update mileage life on these tires. I have the base model with the 18's and they cost me about $740 for the set installed.

They get better once you run the new off them!

Mileage has been great for me I've put about 6k on them and have noticed little wear. They seem to be wearing more evenly especially in the back. THe stock tires wore on the shoulders more than the inside on the rear which was weird considering they had negative camber. I expect the S04s should last me 25-30k as I got 15k on the oem potenzas. The only downside with the S04s in my mind it seems that the initial turn in on high speed lane changes is a little sloppy or delayed not crisp and immediate like the stock potenzas. The S04s seem to be much grippier in temps below 50F too. For the price its a really great tire.

yah, unlike the S03s and RE050A's, the S04's do in fact grip better at lower temps. :tup:

in related info, Advans suckarse under 50F... holy hell dorifuto tires. :ugh:

I don't know what it is about the compound of the S-04 but I'm finally able to smoothly peel out from a standstill. Before with the RE050A and disappointing Hankook V12's, there would be horrible wheel hop like the car was breaking apart. Those tires were able to peel if I got them hot enough after some spirited driving on a hot summer day, but otherwise wheel hop for days.
Also, I don't know if it's a coincidence that the VLSD is giving out or the added grip of going 285mm with the S-04 is making it difficult to execute drifts now. I find myself spinning out more frequently and maintaining the drift requires a different amount of throttle.

I did the stock sizes for my 19" and it does not drift as easily. Much better wet and dry handling as well than the stock RE50A

So far so good for me - I've had mine for over 14 months now, but only about 7K miles. They are wearing just fine, and I'm just as impressed with them now as I was when I first bought 'em. Much better tire than the OEMs!
