Okay, so I have decided that I FINALLY have enough money to get my rims/tires. I am going to be ordering Volk SF Winning in Mercury Silver in 19x9.5" +19, and 19x10.5" +29. I don't want to deal with the hassle of rolling/shaving my fenders, so this is the better alternative for me (versus a +17 offset in the rear).

Having said that, I need advice on tires. What size should I be getting? Would 245/35/19 and 275/35/19 be fine? I know some people run that on a 9.5/10.5 setup, but is that "safe"? Or should I move up to a (less standard?) 255/285?

Also, what brand of tire is good? Toyo's seem to be reasonably priced, but now they have a new T1-R which is supposedly better than the T1-S in every category. Should I get the T1-S or the T1-R? What are other alternatives?

TIA

 

ive gone with the 8.5/9.5 on the volk gt-av's +23/+24. Im thinking of going with either the Toyo T1-R or the Fuzion which is made by Bridgestone or BF goodrich..i cant remember, however the Fuzion/Toyo are awsome tires. If I go with the Ultra performance Ill stick with the Toyo, however if i go with an AS high performance illgo with the Fuzion, in the 245/275 or 285 in the 35 series tire..Please dont go with a 30 series tire. Cheaper - yes, safe - no, ugly - most definitely with a stretched tire. Good luck.

 

Thanks for your reply. Whatever I end up going with, I will definately NOT be getting a 30 series. If I have to go with the 285/35, then Toyo's are out of the picture...

BTW, can anyone explain exactly what tire "stretch" looks like? I know a lot of people mention it, and it is considered a bad thing, however, I was never quite clear on this concept. Can somebody elaborate? Possibly post pix of stretched vs. non-stretched tires? My understanding is basically that a stretched tire barely covers the wheel width, whereas a non-stretched tire may be as wide as or wider than the wheel. Or maybe I'm completely wrong

 

Easy, tire stretch pictures are below.

Remember how tire sizes are, example:

275/35/19

275 - represents the width of the tire in mm's.

35 - represents the height of the sidewall, or the Aspect Ratio. It is a percentage of the tire width. In this example, you would take 35 percent of 275 millimeters and this would give you the sidewall height.

19-And of course this represents the diameter of the center of the tire in inches.

So if the width of the wheel is too wide for the tire width the side wall will stretch. Now Im not sure how to scientifically say it and there are others here that can explain it alot better than myself but the pictures will explain it. I think there is some formula but honestly im not sure.

The pictures im putting, God i hope they dont get mad at me putting them up, are examples of some tire stretching as I see it.Beautiful cars and beautiful wheels, but the tire just looks "stretched". there is no protection of your wheel on the side wall, ie from curbing, maybe hitting a pothole etc.. but im fairly new at this. Im sure there are other reasons.

 

bhasha, just some things i had to make decisions about with my rims that you might want to know.

With that big a width in the back (what I have also), your definitely going to see stretching if you go with a 275 there. I think the only reason people ever go with a 275 back there, is because they dont want to do the fender rolling/cutting and a 285 is a beefier tire that will require more rolling/cutting. Im going with a 285 as I have no problems with allot of rolling, and i also do not want the lips of my rims out in the open like you see there with a 275.

The 9.5 should fit pretty good up there, you might have to do a little rolling but the rear is where the most rolling is going to be required when you go with a 10.5. But dont worry about it, 10.5 is beast and youll love it.

GL, are you at stock height or have you been lowered. I was wandering about rolling the fenders, if I put a 275 or 285 on a 9.5 rear wheel? Any suggestions? Im still stock height but putting on the tokico shocks and eiback springs.

 

Hey I found this, and im not sure if it will help you but I found this on ebay. I contacted them and they seem to be really nice. Its the same company that are selling the Ruff Racing wheels. They told me the other day they had about 10 sets of these wheels left. Hope it helps.

Amit I'm very happy for you! Finally getting the wheels eh? ( I guess who should talk I dont have mine yet--hell desiz beat us both).

As far as stretched/non stretched goes NC hit the nail on the head description wise. I couldnt have said it better myself. Just remember if you're running 30 series on the Z or if you can see the lip not being protected by the tire, you're most likely stretched.

If money was no object I'd rock the KDW 2's from bridgestone. The T1-R is a very nice tire. Personally I'm going with the T1-S b/c my friend is getting rid of a brand new set (a shop).

Anyway, let me know what you do.

ncparamedic, depending on what offsets you have I can help you out. 275 on a 9.5" is commonplace here. I've seen people with 10.5" on 275/35 with eibachs and +24 offset with no rubbing. Its all in the offset, width, tire size.

Peace!

If you want to keep the stock stagger from fron to back, and not have potential problems with the VDC or increased understear then u need to go with 255/35/19F, and 275/35/19R. These are the correct sizes.

For a 275 width tire a rim 9"-11" wide is acceptable.

Thanks all for the replies. I'm getting closer and closer to ordering the wheels and tires

So will I have to "roll" the front? I never heard of any problems with the front at all, but then again, maybe I just never noticed/read up on it. I always figured the front was fine, and the rear was a problem and would need to be rolled. What offsets on your 9.5 front? And what tire size did you opt to go with?

Yeah, I may have to consider something else if I ditch the 275/35 rear for a 285/35. I don't believe Toyo's are available in 285/35/19.

Are you sure the correct size is 255/275? I always thought it was 245/275...

 

Ooops...aparently the new Toyo T1-R are available in 285/35/19 (according to http://www.toyojapan.com/new_tires/proxes_t1r/list.html)

So if I go with a 285 in the rear, do I go with a 245 or 255 in the front?

 

Well the stock Track size is 225F/245R. So the 255F/275R keeps the same 20mm difference.

the pics in the 4th post are of a 30 series tire. a 275/35 will look a little different (better). a 275/35 doesn't look bad at all, imo, on a 10.5" wide rim. only thing that bothers me is protection from curbs, but drive careful and you shouldn't have to worry about that .

 

I put this together...

Correct 18”-19” +1 Tire Sizing

Front Diameter Comparison

Move From Tire 1 225/45/18
To Tire 2 245/35/19

Stock 225/45/18 diameter is 25.97”. The closest diameter to stock is 255/35/19 2 26.03” a difference in +.06”. The difference in diameter between a 225/45/18 and 245/35/19 is -.22”. The closest size to original diameter is the 255/35/19.

F/R Diameter Comparison

Front Tire 1 245/35/19
Rear Tire 2 275/35/19

As per Nissan overall diameter difference between front and back should not exceed .72”. 255/45/19 275/45/19 has a difference of .55 which is within specs for diameter, and keeps the 20mm difference in width between front and back which keeps understeer as stock.

245/35/9 and 275/35/19 has a diameter difference of .83” which is out of spec per Nissan. It also increases the stagger from front to rear to 30mm increasing understear.

Those are the facts…

You meant 35's here right?

No disrepect JET, but can someone confirm JET's post? Cause like alot of ppl here, All i've read in the forums are 245 in the front, and 275 in the back. And if you use 255/35/19 in the fronts...would 19x8.5" rims fit well with those tires?

So the final sizes if you go +1 should be:

19"x8.5" with 255/35/19 in the front
19"x9.5" with 275/35/19 in the back?

Thanks for the info JET

 

Sorry.... yes I meant 245/35/19 front, and 275 35/19 rear.

The 245 front application arose from availability. There are only a few manufacturers making both 255/275 sizes in the same tire. There are manufacturers making cheaper tires in the 245/275 sizes.

Here is the revised post in full

Correct 18”-19” +1 Tire Sizing

Front Upgrade Diameter Comparison

Stock 225/45/18 diameter is 25.97”. The closest diameter to stock is 255/35/19 2 26.03” a difference in +.06”. The difference in diameter between a 225/45/18 and 245/35/19 is -.22”. The closest size to original diameter is the 255/35/19.

F/R Diameter Comparison (FOR VDC PURPOSES)

As per Nissan overall diameter difference between front and back should not exceed .72”. 255/35/19 275/35/19 has a difference of .55 which is within specs for diameter, and keeps the 20mm difference in width between front and back which keeps understeer as stock.

245/35/19 and 275/35/19 has a diameter difference of .83” which is out of spec per Nissan. It also increases the stagger from front to rear to 30mm increasing understear.

Those are the facts…

Well, yeah u prolly wont have to roll the front, i didnt see what size you were considering up there, chances are youll only have to cut or roll the backs, especially witha 285.

I am on Tein Basics with SPC camber/toe arms in the rears. Ill let u know what my final numbers and fitment is when i get my rims and fenders rolled and everything is final within the next week or so here.

 

The rim width range for a 255 tire is 8.5"-10". So you are solid.

Respect
JET

 

lol, omg. that stretching in the first pic is so extreme. you can balance a beer can on top of that sidewall.

 

Jet is soooo smart. I knew there was a mathmatical way of saying it but I wasnt for sure. Thanks jet. You also helped me realize that maybe I need to stick with the 255/275 so my vdc does mess up. I dont mean to sound dumb but how are you calculating or converting the diameter of the wheels? What is the formula. I understand the staggered thinking from f/r 20mm spacing but what about the other math you did. Thanks again.
