Rear tyre size
#16
Similar situation my F is DD, I drive to NYC 5 days week from Westchester County. NYC roads can be rough and after replacing several sets of tyre due getting bubbles on
side wall from pot holes, etc as well how the car handled. I went from 245/35/19F 285/30/19R to 255/35/19F overall diameter 26inches with section width of 10.1 inches 275/35/19R - 26.7 inchs overall diameter with section width of 10.6 inches. Thats .5 difference in width nearly square set up. For me this setup provides several benefits 1. better side wall protection from road imperfections, 2.since nearly square set less understeer more neutral feel. 3. More grip up front 4.The additional side wall provides for smoother more supple ride which translates to faster driving especially over poor roads. On certain sections of highway my F use to kind of slide over patches of bad roads in turns, now much more planted feel not as skittish. Some may not like look of taller sidewalls but for me it's more functionality over looks. Heres pic of my F with 255/35/19F 275/35/19R setup.

Cheers mate, some said 275/35 didnt look right vs 30 profile. I know you drive yours alot like me, daily ride and you are on the Sydney roads like me. Im just worried 30 profile for the rears regardless of width will be too thin, bumpy etc, thats my main worry. Touch bumpy on my OEM 35 profile now so wasnt sure how much difference that 5mm makes.
Seen St George, yep they are good on prices. Usually go Tempe but seen Taleb have a few specials. Think they are all owned by the same family anyway lol

I think you are under the impression that a 30 profile is shorter then a 35 profile regardless of tire width and that's throwing your thinking off. As the tire gets wider the profile gets taller for any given profile. The 305/30-19 PSS on my car is going to be taller then a 275/30-19, so as you get wider the tire gets taller and there is less worry about being close to the rim because you have "low-pros". I think Lou did the math for you on page one of this thread.
Honestly you are splitting hairs worrying about the ride quality between the two,I doubt you will ever really notice the difference. Go with the wider tire if that's what you want.
If you are really looking for some internet talk about ride quality between two tires I think that comparing make and models of tires for there build and compound specs will matter more then the difference between two similar sizes in the same tire.
This is like having a talk about turbo lag between two similar turbos......

...welll....
I just upgraded wheels/tires and went with 19x9.5 +40 offset on all corners. There's no rubbing (except on one front corner where the wheel liner is deformed inward)...
Rubber is the new Continental ExtremeContact Sport in 275/30/19 - great tire! I noticed they do have it in 285/30/19.
Any brave souls care to try it out??
Edit: The only other possible downside, the 275 is listed at 23.5 lbs - very light for a tire this size, while the 285 is 25.9 lbs per tire, so going slightly wider/taller would add 10lbs of rotating mass. Not sure the trade-off is worth it.
