2009 Nissan GT-R: Tired Front Tires

expensive coincidence, when you consider the X5 almost needed em (cause of the screw) and the R8 has already gone through a couple sets in its longterm stay.

What next? The '05 TDI?

The gt-r isn't as cheap as the sticker says. Especially if you use launch control and void the warranty.

You should put on economy low rolling resistance tires and see how it does.

those don't look like ANY fun in the wet, even with full... anyone tried it, care to comment?

Oh be sure to get the DUNLOPS instead of the Bridgestones when replacing.

For 2010 the Dunlops are now standard fitting on all GT-R's and they offer better performance. They'll better reflect the OEM fitting as the Bridgestones appear to be getting "phased out."

I guess in the flatlands, it's possible to get a lot of miles out of tires. Here in the hills of the Rust Belt Western PA, getting 20k out of performance all-seasons is normal and anything more then 30k is nearly impossible,even with normal rotation.

You can't have ultra-performance and long tire wear. I think 12,000 miles for the tires on a Skyline isn't all that bad. Tire Rack says $1610 for the Dunlop DSST Run Flats.

If you don't have the money for $1800 a year in tires, you shouldn't have a Skyline GT-R.

The trouble with the Dunlops is this: we'd have to buy 4. A full set from Tirerack costs $1,610, plus mounting.

If we stay with Bridgestone, we'd only have to buy the 2 fronts, at $736 plus mounting. What would you do in today's economy with a pair of rears that still have life left in them? And why add tires to the recycling heap before they're used up?

Oh, I wouldn't replace the rears if I didn't have to. As much as I like having 4 tires around the same age and treadlife, if the rears have life, let them go. That cuts your tire cost in half (including mounting).

They might not be the best tire, but if they don't need replaced, then I wouldn't. In another year, when the fronts are shot again and the rears too, then I'd upgrade to the Dunlops.

You've gotta pay to play. The cost of tires is a major component of owning a performance car. Just a fact of life.

Nice slicks! j/k

565565, I'm not sure if the Dunlops are "better" than the Bridgestones. The former are the SP Sport 600 DSST (IIRC) and the latter are the Potenza RE070R. Using the previous-gen STI (Potenza RE070) with the current STI (SP Sport 600) as a *general* example, the RE070s have stiffer sidewalls and better response than the SP Sport 600 tires.

After all, weren't the RE070Rs optional on the new GT-R because they were the "better" tire?

subytrojan, according to Nissan, the SP Sport 600 is a faster tire in the dry then the RE070R, it is worth 4-5 seconds around the ‘Ring. The RE070R is quieter and better in the wet. The 7:29 was done on the SP Sport 600.

$1610!!! Holy crap!

If you're wearing out the inside of your tires like that, you do need to tone down the negative camber. I know it's not manly to go with a less aggressive alignment but it just means you're using the GT-R as a daily driver, and the performance alignment is more for track queens.

if you only buy two, make sure you put them on the rear and rotate the rears to the front.

i know a lot of you won't agree with me. but before you argue, beware, i have about 15 links from manufacturers (goodyear/michelin/dunlop, etc.)and retailers (tirerack.com/discounttire.com) to back it up.

unless, of course, your tire sizes are staggered, which they probably are on this kind of vehicle... too lazy to check.

then i guess you should probably just replace all four.

Perhaps this car could be nicknamed Audrey II, as it keeps yelling "Feed me!"
Odd that just the innermost edges are corded - otherwise treadwear seems fairly even.

Don't you guys have to cut back on expenses too?

You should replace all four tires at the same time. As stated by Nissan, and within the Disclosure form you signed when you took delivery of the car, it states "The Nissan GT-R is equipped with high performance, low profile, run-flat tires that are optimized fro performance and handling... In many situations it may be necessary to replace all four tires if only one tire is worn or damaged"

So, purchase all four, or none, and stay safe with the vehicle.

This GT-R does have different size tires front and rear. The Bridgestones have a 140 treadwear, the Dunlops 220 or 240, something like that. I looked them up on Tire Rack.

automobile had a GTR and GT2 at the Ring and both were driven on the same day by the same driver with some racing experience. The GTR did not come close to 7:29 and was 7 secs slower than the GT2. They mentioned it did not have the dunlops but as mentioned earlier thats good for 5 secs. I'm sure this will be on the internet soon and GTR fans will be up in arms.

You'll find that negative camber alone does not wear out tires, at least as fast as toe out tends to. I have run several cars with anywhere from -2.5 to -3.5 degrees of camber and zero toe and have gotten plenty of life and mostly even wear (ie insides cord first, but the outside had no tread anyway at that point.) I bet Nissan also specifies a decent amount of toe out in the alignment spec. (similar to the way the 91 NSX has a ton of toe in for the rear suspension and ate tires like they were going out of style)

gearhead1977, then the only thing to do is buy all new tires. new tires only on the front contributes to dangerous oversteer regardless of drivetrain as stated by all the manufacturers and retailers i listed (and more i didn't list).

sorry insideline, goes with the territory!

$1600, cha ching!

oh yeah, might want to get that less agressive alignment done now that you know two worn tires = four new tires every time!

WTLY (welcome to last year) - I know the Ring times were done on the SP Sport 600s when Porsche was claiming Nissan did the impossible.

But I didn't know about the time savings. :thumbsup: You're not so lazy after all! :o)

welcome to the world of AWD. 1 goes down, must replace all! the problem is this car was used too much as a commuter... you need to be hitting the canyons with it and track days with it! then the alignment settings could even be more aggressive!

$1610? That's it? That's really cheap.
That's no more expensive than many luxury sports cars, or even just plain sports cars.

kitw's probably right about front toe. I run zero front toe on my car so it didn't even occur to me, but it does make a lot of sense.

"But I didn't know about the time savings. :thumbsup: You're not so lazy after all! :o)"

subytrojan, I am only lazy on things I don't care about :-)

Looks like the tire pressure are too low and not enought toe in. I run -1.75 camber and my tire wear are perfectly even!

Yipes. I'd have a hard time spending as much on tires each year as I do on gas.

How did the car feel with the tread worn like that? Were you getting vibrations under braking and while steering?
