Seeking tire/wheel/stance experts

[Cfarris87]

Evening guys, been doing a lot of my own research the past few nights buy y'all got more experience. Tiresize.com and wheelfront have are awesome resources Might be a bit of an involved post... I'm lowered on ARK GT-S. I'd like to stick with 19's but I want a bit meatier sidewall. Looking at a 19x8.5 and 19x9.5. From what I've seen, perhaps 245/40 and 285/35 in back or 255/40, 295/35. Definitely don't want much poke, but a bit more flush and filled out than the stocks. Would 255 be a bit too wide for an 8.5? Also wondering how much offset in the back. Tiresize says a 285/35 in the back at +40 is only a half inch closer to the suspension and .7'' farther out. Thoughts on look/stance/rubbing issues with either of these? I think a +30 will be good on the front offset.
Any insight is much appreciated, don't wanna drop 3k+ and be disappointed lol

This is the place to get the info you need on wheels, offset and tire sizes. Surely you've read the go-to thread? Wheel/size/offset and tire/size/profile...can be confusing.

255 is actually about the max recommended tire width on an 8.5 wheel; that is stock in the rear. But you are talking about in front.

I know from all of that plus repeated conversations in other threads (I just talked about this again this morning) that 255 in front is dicey; 245 on the right wheel in front works for a lot of people; 8.5 wide in front and even 10 wide in back are very common wheels; offset between 25 and 40 in back works. I have 8.5 wide at 40 offset in front, and 9.5 with 39 offset in back, using the stock Michelins. But I don't want to come close to poke and never sought flush either. I think it is close to flush enough: but obviously a 245 in front (with something like 30-34 offset) and 275 in back would make the look more like flush.

 

[Cfarris87]

Yeah, I looked through that. Just figured out how to make the spreadsheet make sense lol Looks like i'll be sticking with 245 on the fronts. I found a lot of pictures with different sizes but a lot don't have pictures that really show the poke/flush well enough to tell, on top of sharing offset/tire specs lol Perfect pics though, helps a lot. Your offsets look great though. I think with a little more meat, that's exactly what I'm shooting for. Thanks!

Adding more struggles now... lol settling in on 255/40/19 and 285/35/19 but the tiresize shows them being 0.6'' difference in circumference or a 0.4% difference. I've got AWD, is that going to be a problem with the AWD? 245 and 285 bring it down to 0.6" difference. I'm seeing 1/4" of difference stated by subaru but nothing on our awd system

A "0.6 difference from stock or from each other? The difference between front and rear on the stock tires is "0.1 front to rear. As long as you stay within that difference from front to rear you should be okay even if the overall diameter is different.

Im running 255/40/19 in the front and 285/35/19 in the rears with AWD and its been fine, though my Speedo is a bit off, so I would recommend 255/35/19 in the fronts and 285/30/19 in the rear.

I'm getting from you that you recognize 245 as the consensus widest tire in front: but you believe that you can stretch that to 255, "more meat". Hah.

Well, using your OP offsets, +30 front +40 back the calculator looks like this:

You pick up some "positive scrub radius": I have not heard anyone address positive or negative scrub radius: is this some kind of added wear/stress on the tread?

You get closer to stock OD, but the difference in OD front to back is more than stock and more than what you are on right now. Over time, would this be a problem with AWD?

Honestly I couldn't tell you. Car seems fine so far though.

255/35 and 285/30 are actually almost a full inch different in circumference though lol

In response to Merlin, upon digging a lot more last night, I'm seeing a lot of stingers running 255 in the front with no issues on a 8.5. From what I'm seeing on scrub radius, it's a very small amount that wouldn't have much of an effect, if at all, on wear/drivability.

I just called a dealer and he basically said "uhhhhhhh it's just showing me factory recommended tire sizes" The closest I can get them to match on tiresize is the 255/40 285/35 at .4"

And yes, Redleg the difference is front and rear, not to the factory size.

Yes, sorry. It should have been a 245/35/r19 for the front and 285/30/r19 for the rears.

 

[Cfarris87]

I see, almost exact. Really don't want to go down to 35/30 though. I'm a travel nurse so I do travel a bit, so I never know what quality of roads I'm coming into lol Quite a few AWD's in the Google doc with 0.4 difference on staggered setup

35/30 is not that much different than 40/35 and your speedo will actually read correctly. though if you are doing lots of traveling you may just want to do 255 square for easier tire rotations and replacement if something where to happen.

 

[Cfarris87]

Yeah, that's in the real of possibilities. Should probably stick with 8.5'' if I don't prefer a more stretched tire look, yeah?

8.5 with 255s with a 15mm spacer in the rear should give you nice and flush all around.

 

[SRV]

Yes, sorry. It should have been a 245/35/r19 for the front and 285/30/r19 for the rears.

Yes, this is spot-on, and what I'm running on my AWD.

I would prefer to run:

255 35 19
295 30 19

...but there are no all-season's in those sizes for 19's.

If you are running 295s, you shouldn't be using all seasons or winters anyway. You want skinnier tires for winter to slice through the snow.

No, because you aren't going to be driving a stinger through a foot of snow where that would even matter.

99.9% of the time in winter, you'll be on some kind of hard surface where skinnier tires will work opposite of that. If it's a few inches of snow, you'll be fine on winters. If it's more than a few inches, your front air dam will be a snow-plow long before you need to "sink in" with snow tires to get enough traction.

How far north are you? cuz In my area we get snow storms at least once a week that it would very much be the case. 295s are also just frankly a waste of money for cold weather tires as well. Tires will lose grip just the same in half an inch of snow as they would in 6 inches of snow. I mean, there is pretty obvious reasons why snow tires wider than 245s are far and few in between compared to summer tires....

61N. Anything that falls on the ground will freeze overnight. Most of the time it's snow and cold, but no matter what, snow gets impacted over time, turns to ice, roads are mainly compacted snow and ice near intersections. I still say if you are having to drive through that much unplowed/uncompacted snow, a stinger isn't going to cut it anyway. If you are in a warm location where it's snowing, but the ground isn't below freezing, hence, you are just penetrating to slush, it's more about hydroplaning resistance. This is typically the case at lower latitudes, but not here. People tend to freak out at those lower latitudes under those conditions, thinking they need crazy tires and vehicles for it. Turning and braking traction is much more important up here. The narrow tire for snow thing is taken way, way too far. I'm not saying 295s are good, but it's also not that you have to use 205s or something either. A good square setup you can rotate is generally a good idea.

I’m in Colorado and run 255f/265r/35-19 dws06 continental tires on stock standard wheels .they are wide enough that I get a lil pot hole protection. Seems to get less under steer on hard turn in. Really hard to get the tires to break loose .(I put the effort in )
