is there any disadvantage if I put 275 tire on 9' rim?
Ive ordered new rims 4 month ago then I got them about 2 weeks ago..
When I ordered them..
they said it's gonna fit on my car if I get 19x8.5 for front n 19x10 for rear..
then they made it..
But the thing they didn't know was..
our AMG caliper is bigger than regular c-class..
so after I got the rims..
fronts were great..
but both of rear rims were stuck on the caliper..
so now.. they r suggesting me getting 19x9 rims n also they were saying 275 tires on 9' is totally fine..
Is it right?
any disadvantage or smth like that?

Who are these bozo's giving you advice. If these guys knew about a C63, and also what they were doing, you wouldn't be having this isue right now. A slightly narrower wheel will not help, it's your offset that is causing your issue. A wheel spacer could help you in this instance. I personally don't like spacers. But seeing that you are stuck, I would consider it. Especially if the wheel is hitting against the calipers. But with the right offset, this all can be eliminated.
Offset
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).*
Zero Offset
The hub mounting surface is even with the centerline of the wheel.
Positive
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We have test fitted thousands of different vehicles for proper fitment. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.
*Backspacing, similar to offset, is the distance from the hub mounting surface to the inside lip of the wheel (measured in inches).

Thank you so much for ur kindness..
But what they said was "u can use the spacer.." after I told them I got this prbm..
however.. I didn't wna use a spacer on my car especially w/ customized rims..
IDK why.. but the weird thing is.. y can't they make 10' w/ right offset..

it's not just offset, but the clearance the rim gives for calipers as well. You could have two rims with the same offset with different amounts of caliper clearance, causing the issue you're having now.
What offsets are your rears currently and how far off are you to making them fit? From what I've read 10" rims are a tight squeeze and if your spacer is too thick, you could cause your rear tires to rub against the rear fender.

and the range they can make is +26~+44..

I'd suggest you demand all you money back and go to a shop that knows about what fitments work. In regards to a 275 rear tire with the same aspect ratio as stock, it will be taller effectively lowering your final drive ratio. A good think if you want better milage but not so good for acceleration.

They should be able to it's just they don't know. I'm running 20x10 right now no rubbing, and it doesn't hit the caliper. It doesn't seem like they know what they're doing. I say go with different brand.

I'm afraid spacers will not help u as it will make ur rims stick pass the fenders causing rubbing with ur 275. It could work if u stretch some 225 tires though.. Like the stretch & poke guys. I would just return the rims for a higher offset. Good luck !!

Hi Dr Q, I'm afraid ur offset is too low on ur 19x10.. + 42 or 43 will make the spokes to hit the calipers for sure. U need something higher than + 50 to clear the 19x10 on our cars.

what they said was..
they shipped spacers n special bolts to me..
I also think it wouldn't work.. but.. I will try then.. it doesn't work..
they were saying.. full refund!!

It will work.. It will solve ur calipers rubbing issue, but it won't look good. Plus, be prepare to rub if u have passengers or drop ur car in the future.
Basically, ur spacers will make ur offset lower. For example: 10mm spacers will bring ur +42 offset to + 32 offset. It's way out of wack for our cars. Trust me, don't accept their spacers offer, just get ur full refund before it's too late as most companies will not refund wheels that has tires mounted. Beware my friend...

Now before everyone brings out the bats and torches... let me explain some information that is going on in this post....
The wheels that we're ordered are the F05's that we're built with a custom two tone finish and pin striping, the main reason for the extra time was the custom finishing...
the wheels that are ordered are 19x10... most of you all know that we supply most of the forgestar wheels to this forum, so I've got to say that i have a pretty damn good idea what will and will not work.
Now with this being said, the highest offset for the 19x10 F05 is a 44, which this wheel was built for... the main issue that we are having is the spoke design, that currently does not clear the AMG caliper, had i known this was an issue we would never have even begun this order, but from what we we're told from forgestar these would fit without a hiccup so we proceeded.
The higher the offset number the further the wheel will sit in, so if Q had an offset of 50, these wheels would still not work because of the spoke design. The 44 offset according to forgestar on these F05 would fit in that perfect pocket of clearing the brakes and clearing the fenders. Would i have preferred to have 46-50 of course, however with the spoke design of the wheels, and trying to clear the rear calipers, we needed as large of a back pad to make the 10's work. The other suggestion was to run 9's (less preferred) with a 265 tire. Even running the 265 would be highly suggested as this will not be a highly aggressive fitment even with a 3mm spacer.
We stand by what we sell, so of course New York offered Q a full refund, however he wanted these to work as he loves the way they look. So that is where we are, Q will have his 3mm spacers on Wednesday and we'll wait for him to report back.

Thanks James for the details.. I'm not bashing ur company as I heard great things about ur customer service!!
But I've also read numerous times about bad fitment with Forgestar.. Specifically in x10 sizing. 3mm spacers is very minimal though, he should be fine without looking goofy.
Let's hope it clears the fenders now. Good luck!!

my 18" f14s barely clear front calipers...like 1-2mm which caused some scratching. Forgestars great price tag, but you get what you pay for i guess
solid customer service is rare these days tho, ACG always FTW

Post pics of your wheels Dr Q, I bet you must have a nice concaveness in the rear.
You'll sure push this car to a new level if you can squeeze your 19x10 + 41mm (w/the 3mm spacers) with 275 tires.
Well, at the worst, you can always roll or pull your fenders.

The OP stated Forgestar has maximum offset of +44 for this rim... So with a 3mm spacer, it should become +41.. I'm no wheel expert, but I have 19x10 +53 w/275 tires & it's a tight fit.
Dr. Q, is ur car lowered at the moment?
