Don't rely on anyone but yourself. Most vendors are middlemen and have little technical idea of what they're selling. As mentioned, perform your research so you know exactly what you're getting and what should fit.
Wheels are a funny business to be in. There so many layers to fitment. Fitment aside, there's the issue of safe handling. For example, wheels that stick out too much put uneven load on the hub. Resulting in premature hub bear wear. Some don't care about this as they're in it strictly for the looks.
According to michelin, the pilot super sport in 245/40/19 will fit a rim of 8-9.5". Their printed tire specs (diameter, revs per mile, etc..) are based on a rim width of 8.5". I would of looked up your specific tire, but you didn't specify an exact toyo proxy model.

I'm glad the vendor is working with you. Right or wrong, he may have left out the discussion of offsets to simplify the transaction since you made it clear you were a novice at wheel/tire fitment. Offsets can be extremely confusing and complicated, and are hard to explain over a short phone call. Offsets are also only part of a complex equation that results in the final fitment. Alignment specs play a huge factor in final fit. A difference in a degree or two of camber makes the same size wheel look either past the fender, in line, or slightly tucked.
Did you end up with Forgestar wheels?

I think he may have left that part out to simplify it as well. That was my best assumption, at least. I ended up with the TSW Bathurst actually. The more i looked into the actual weight, the more I felt I wasn't going to get anywhere near what was advertised.
hey is my email with jason when i was looking for wheels

if you notice the email he sent back was not what i was asking for..he could have just said i don't have Matte black in 18x8.5 +35 in stock.
instead he quotes me a 18x8.5 +30 in silver

Assuming both clear the calipers, realistically speaking, how much difference is there in a +30 vs +35mm offset? Numerically it's 5mm, but does that translate into a significant visual difference?

So this is the email I was given this morning:
I don't believe they have a mark on them even after lugging them around anywhere. Not quite sure on how I feel about them shaved down.....but, one bridge at a time.
It really depends on the condition of the wheel that was mounted.
If the wheel is perfect with no scratches and TSW cant tell the tire was ever mounted then we'll get them swapped out for you no problem
Only other option available is 19x8 +35 all around, does that work for you? This fits 18mm further in than the 9
If it is scratched up from the mounting/unmounting TSW wont take it back and we wont be able to return the wheels. On the TSW boxes there is a sticker that specifically states to test fit the wheel before mounting a tire or they wont take the wheel back.
In that case then I can have the wheels shaved 3mm for you to make them a 19x9 +33 and that should fit better
This is a G37 x sedan running 19x9 +30 wheels with 245/40/19 tires and it fits perfect flush

well for one they didn't have the matte black i was looking for.
and if i wanted a +30 offset i would have asked for it..
the point of the story is i asked for a specific wheel and offset and he tries to sell me something i didn't want or ask for.
The marks will be on the outer part of the barrel from mounting the tires (the part of the wheel covered currently by the tires). The marks will almost certainly be there. This is just a fact of life when mounting tires.
No offense (just rationalizing), but I didn't see anything too bad about his e-mail. He's a sales guy trying to make a sale and went out of his way to let you know your other options. Sometimes people are flexible on wheel color and what's in stock sways them one way or another. I know this happened when I ordered my wheels. It was nice to know my options.

My question was more so about the significance of 5mm offset (1/4"). That is, just how important is that in the scheme of things so long as the brakes clear.

I looked over the two wheels that were actually opened and played around with. There's not a single mark on them; no scratches, smudges, abrasions, gouges, etc. Although the "tire specialists" did mention they could get the tire back off without damage.
I, also, was very surprised at this. But they're flawless.
I understand that. Especially the color part. You're really interested in a black car but get sold a white one instead.
