Questions 275 30 19 or 275 35 19 which is better size for Rear tires
I understand the size difference 25 .5 vs 26.5 as well higher and lower speed and mileage differences between these two. My question is is it better to go .5 under or .5 over the OEM stock size which of these two size is overall better feeling, handling, etc size to go with? Or there is no drastic difference between the two sizes when it comes to driving characteristics.

From what I understand the 275/30/19 size is more popular because it gives you a slight gearing advantage and with cars that are lowered anyway it gives you a little more leeway on not rubbing before you have to roll fenders?
I'm sure someone will chime in and give their opinion on which one is better for their particular circumstance.

275/30 will be better from a performance perspective, as it is closer to the stock diameter and the revs/mile will be within spec in relation to the stock numbers. I know 275/35 has been mounted before, and from what I have read, it is purely for those wanting more sidewall protection in areas where roads are less forgiving (potholes, bumps, etc.).

Assuming you're looking at the PSS, I wouldn't hesitate to get the 275/35 if the 275/30 is on back order again. Another way to look at it (and someone please correct me if I'm wrong) - if you've been on 275/30 for the last 20k, you're odometer is going to have 400 more miles than it would have had on OEM size. If you run 275/35 for the next 20k, it will even back out!

I've had 275/35 and 275/30. I would go with 275/30. IMO it looks much better. 275/35 the back tires wall just looks too thick. (I wish I had pics)
Your odometer is off by ~ 2% either way. Under with 30 and over with 35.

I drive from the suburbs to New York City Daily the roads in The Burbs are Nice & Smooth great shape but once I get to the city they're pretty crappy so that's also a consideration when deciding. Any that have had both interested in your input as well as those on just 275 30 19 ride quality looks etc.

To be honest its kind of hard to say since I had two different sets of tires.
When I had 275/35 I was using Contiental Xtreme Contact, they are a bit soft to begin with, especially when cornering you can feel a bit of a lag in the steering input.
Now I have PSS all around and its a world of difference on its own. The ride quality and handling is much better.
We have some crappy city roads here in MN as well. Again this could just be the tires, but 275/30 feels better.

Hey Orthodoks I here you on Conti not my fav either gad them. That's interesting I would think that 275 35 might feel slightly better on crappie patched pot holed uneven surface roads. How tire gap

I'm sure the 275/35 will feel better on crappy roads, but I think you will be giving up a little bit of handling.
The gap is better with the 35, but the thickness looks weird to me, the wall just seems too high, like drag tires on a muscle car.
The 30 looks cleaner. Let me try to find some pictures when I get home.

Last week i went from stock OEM to a 275/30-19, which i like much better in looks. as far as ride, they are a bit softer but this may not be very helpful; i went from the original Potenza RE050, but they had some solar cracking and hardening, so anything would feel better than those.
I know there's some Pirelli-haters here but I'm mostly a city driver and I got a deal on some Pirelli P-Zero Nero GTs and so far I really like the feel. (as many do here; i went with 245/35-19 on the front)

Can I take us off topic for a moment?
I'm very curious on sidewall heights. Take these sizes for instance: 255/35/19, 295/30/19, 285/35/18. The circumferences of these tires are VERY close in diameter, so much so that we can ignore this parameter. Besides the tread width there's the issue of the sidewall height. Compared to stock, the 295/30/19 has LESS sidewall height, is heavier, and will likely handle sharper when mounted on a correctly sized tire because there's less sidewall flex. What about the 285/35/18? You gain a half inch of sidewall height (meaning an inch of diameter) with a larger tread width and gain some tire weight. How is that going to impact the handling? Especially on such a heavy platform.

Compared to stock, the 295/30/19 has THE SAME sidewall height.

I could find any decent pics of my own, but did some digging on the forum, here you go.
275/35 PSS actually looks pretty good on the SFP I have to say, but I disliked the Conti that was on my car, the wall was a lot more round.
