I'm looking at getting new tires for my rays v2, was looking at going 285/35/19 rears. For the fronts, will both 255/40/18 and 265/40/18 work without issues? Or would one work better with the 285 rears than the other? If not I would likely go with the lower costing size. Car is stock but will be lowered on stech and koni yellows, and from what I've researched, I shouldn't worry about any rubbing concerns with this set up or sizes

 

Either will work, but I would run the 265 front if you do 285 rear. If you can only get a 255 front (tire availability) just run a 275/35 rear. Last, I would not remove the factory Nismo springs for a pair of S-techs

 

Thanks! I'll look into the 265 fronts. Regarding the springs, don't have a Nismo model, I posted in this thread since I have the rays v2 which are the same spec as the oem Nismo wheels

 

Has anyone gone with 245/40/18 fronts and 275/35/19 rears? Based on tire size calculator, the 275s will be a 3.35% diameter variance from the fronts, vs 2.28% using 265s. Researching through guides on this forum, the general rule is 3%. Would 3.35% be large enough to mess with the TCS/VDC?

Reason I ask is because I have a good deal on RE11s or RS3s in this sizing, so if it won't mess with anything (to be used on dry street and track, with hopefully minimal rain, but can't always avoid), I'd like to get in these sizes.

 

That's what I'm running on my 2008 Nismo.

Car still has the original tires from the factory 245/40/18.

Replaced the factory rears 265/35/19 about 6 months ago with a pair of 275/35/19.

No problems, looks better IMO. Planning on sticking withe 245's in the front when I replace those (they actually still have a good amount of tread).

 

The 245/40 front looks nice, I use that still and a 285/35/19 rear, Bridgestone RE-11's. Great tire, not super light but so sticky I can deal with it. Most of the Michelin offerings are lighter due to the use of polyurethane bands rather than steel. Several pound difference in the bigger sizes.

 

275 / 245 is actually the OEM size the Nismo 380RS runs so I'm guessing it should perform better than the rear 265 without messing with anything. I ended up going with 255/40ZR18 99Y FALKEN FK452 (fronts) and P285/35ZR19 90W GOODYEAR Eagle F1 A/S-C (rears). I didn't want to mismatch tires but the private tire dealer gave me too good of a deal on them that I couldn't pass up. Rears were at 100% and the fronts were at 75%, I picked up the entire set for $270. Plus the tread patterns are pretty similar.
I am on Tein Comfort Sport coilovers and I had them at their lowest setting before I put them on, after install I had rubbing issues with the rears while semi-hard cornering so I had to raise the rear a little, raised the front as well just to even it out a little. Here is how it's sitting now.

 

Ultra high performance on the front an all seasons on the back both with different speed and load ratings? Definitely not a mix match set up Id go with but to each his own.

 

Took a quick trip to some hills nearby and it rides just fine on this setup, I definitely feel the improved difference in grip while cornering. I needed new tires really bad, and like I said main reason I got them was because of the deal I got. If they were more, $$, I wouldn't have gone this route. I'm satisfied for now. l2iceman tire choices are great so in the near future, I plan to switch them out for some RE11s or the RS3s

 

Thanks guys. I'm likely going with the RE11a in 245/40/18 fronts and 265/35/19 rears as they're only $140 (or $200 after mail in rebate from conti) more than the continentals and I won't have any concerns with tracking with them. I don't daily drive the car so not worried about the 200 wear rating on the RE11a. I'm just waiting on a 275/35/19 quote confirmation, and if not much more, I'm going to get those instead of the 265s since the 265s seem to be a stretch on the wheel.

 

^^Sounds like a plan, and again, FWIW, I think the 275's look better, not "stretched", and maybe slightly fill in the fender gap, so if not much more, may be worth it.

 

ok so it turns out the quote I received for the "re11a" were for re11 as re11a are not available in 19s (rears).

So I'm down to deciding on these three, all within $40 of each other, from lowest to highest (including rebates):
Michelin PSS - 245/40/18f and 275/35/19r
Bridgestone RE11 - 245/40/18f and 265/35/19r (275 not available for RE11)
Hankook RS3 (2013 model, not the new v2 for 2014)- 245/40/18f and 275/35/19r

I've read countless "reviews" by searching Google, so many differing opinions, it's hard to decide lol I'm inclined to go with the RS3 or PSS simply due to the availability of 275 rears. From a performance standpoint, is the 275 vs 265 rears much different?

I plan to track, at most, 3 or 4 times this summer (I'm a noob, so doubt I'll be pushing the car to its limits, I'll be focusing on improving my own skills rather than focusing on speed/time) and I drive this car on weekends and once during the week (I walk to work and have a second vehicle).

The RS3 I believe are the only of the three listed that can be swapped left to right for some extra mileage.

 

Run 285/35 on the rear, looks perfect on the stock wheels.

 

I guess I'm going to be changing my tire size to 275 rear and 245 fronts as well. With more driving on my 285 rears, I still do hear the tire rub a little when I make hard right turns. I honestly don't want to raise it up more than I already have.

 

The 285 rear would require a wider front I think, as the diameter difference would be too large. This would also then have the tires fall out of my budget.

 

I think ur right here.

Also, you would be adding alot more unsprung weight to your car, just for "the look" as I don't think there would be any performance advantage.

 

Why a wider front for a diameter difference? I use the stock front with a 285/35 rear and it has no issues. Yes it might be a few ounces heavier than a 275 but really is that the issue? I don't care too much personally, i'm super happy with my RE-11's in those sizes, car handles so well with that much rubber on the ground and it got rid of that ugly stretched look from stock sizes. I have had three different types of tires on the rear, all in 285/30 or /35 and it just looks correct. Some tires run a bit wider though so it may look like too much for some people's taste. I'd put a 305 on there if it would fit the rim nicely.

 

Stock 370Z Nismo tire size is 285/245 but it's wheels are x 9.5" & x 10.5" instead of our x 9" and x 10"

 

Hmm I didn't realize the 285/35/19 rear would work well with oem 245/40/18 fronts. I'll see how much the re11 are with 285 rears, but as it is, I'm leaning towards the rs3 with 275 rears.

 

I had said before that I was going to switch out the 285s for some 275s because I was having issues with a "tire rubbing" sound when I would make semi hard right turns. I thought it was because my car is lowered but NO that's not why. I lifted up the car at a tire shop and I was able to wobble my rear driver side wheel in and out. The damn wheel bearing is shot! Once I fix that, I'm 99% sure there won't be anymore rubbing sound.
