111 means 2403 max pounds per tire

did they even look at the Gross Axle Weight Rating (GAWR) sticker on the B pillar? (see below):

GAWR is the maximum allowable weight for an individual axle. my rear GAWR is 3968 pounds. my 275/45R20 run flat tires are rated 110, which means that the two tires that are on my rear axle can carry a maximum of 4674 pounds. that's 706 pounds more than the rear GAWR. a tire with 110 rating is more than capable. since they're being picky between axles, show them this.

you can even argue that 110 rating is more than capable for the car's gross weight. my GVWR is 6967 pounds. all four of my tires can carry a maximum of 9348 pounds. again, more than capable.

tires with 111 rating can only carry an additional 132 pounds per axle or 264 pounds for the whole vehicle compared to tires with 110 rating... not a significant increase at all! either tire exceeds the vehicle's load requirements.

yep, exactly. they even did the math and said it isnt much, but policy is policy. Ive talk to two different discount and they said the same thing. out of their control. i was willing to sign a waiver and they still cant do anything about it....
as i mentioned on post above, this is an ongoing issue for years. its not about what the vehicle is capable of, but about their policy... not even an argument, its what they are telling me. it is what it is. now you guys now know.

I was just responding to your comment. I honestly do appreciate your help.

as mentioned, my feasible options are
-get wheels and tires else where (went to a few and they want to charge me extra because i have an X5, plus limited tire and wheel selection)
-get wheels and settle for 265/50/20 tires at discount
-go to the dealership and let them rip a hole in my wallet
-get all weather/all season for my current 21s staggered

i do want to get wheels, tires and installation at the same place so if theres any issues, i dont get the run around.

Sure.

From like 10-15 sets of wheel I have changed so far on my previous cars I would not get wheels from discount tire....

There are so many brands that are better quality than what they offer..... and if any issues, they ask you to talk to manufacture.... Mandrus is basically Bayern company for Benz... specifically built for Benz but that means nothing.... TSW and Drag, I would stay away from them on heavy SUV. Yes they are parent company for mandrus but that's all about it


I ususally get wheels from other BMW performance shops from online...

Tires I like tire rack better because they will give road hazard protection for free and no difference on price between tire rack and discount...


Only good think that discount does is free tire balance and rotation but they don't do alignment so have to take other place for that....

Never gotten wheels from them, but we usually get tires from them or Costco and every time there's any issue, they took care of it. the few times in the past we gotten tires from outside of those two, we ended up getting screwed.
weighting our options right now.
thanks,

FWIW, I'm selling my set of winter wheels and tires

Yes and No with your rationale. Bottom line it's must cheaper for them to keep their name off a lawsuit than risk being included so no rationale is going to change their mind.

Gross Axle Weight is a static measurement, meaning the weight an axle can carry measured at standstill. Tire load will always extend gross axle weight because you have to account for dynamic forces in addition to static weight; it's not only the vehicle load weight but the additional weight (= force) placed on the tire by torque and acceleration. Yes in this case the difference is minimal, but it's still below spec.

I had a Nokian Hakkapeliitta R2 SUV in several cars. Nordic type tires. Very soft. Speed ​​index depending on the size of the wheels R, T. I had R - no more than 170 km / h (~ 100 m / h). If the winters are very warm and there is a lot of dry asphalt, then it is better to drive slowly on them. Tires overheat. Not for aggressive riding.

Ended up going with 19" for my winters and alternate sizing in order to get Pilot Alpin 5 SUV tires. 275/50/19.

Everything done per TireRack's website and sizing guidelines so no issues regarding fitment. My only concern at this point is figuring out how to enable the other sizing option within the computer to sync the TPMS. Tire is only 3mm wider and rotational difference between is minimal vs. OEM 265/50/19(1mph @ 90mph).

I was speaking about Gross Axle Weight Rating (GAWR), which never changes. Gross Axle Weight (GAW) does change depending on passengers, cargo, trailer, road forces (you said so yourself), etc., and therefore is not a "static" measurement.

how are tires with 110 rating "below spec"? Bridgestone Alenza A/S Sport RFT 275/45R20 110H are OEM-spec from the factory.

It's stupid but it all comes down to the car's sticker on the door panel. His car has OEM 21" staggered with the rear having 111Y load index rating; that's why it's out of spec even though it's practically the same car as one equipped with 20"s (minor differences exist with engine and speed limit ratings on the G05, but essentially they are all the same). If his original tires were the 20" then this wouldn't be an issue. It seem like we're not going to win this argument with discount tire because of this minor technicality and their risk aversion. It's silly that the dealer is willing to put them on but discount tire isn't.

OP is the cost really that significantly different for the dealer to the job?

i'm actually waiting to hear back from my dealer about getting a new sticker since i converted from factory 21" staggered to 20" squared.

this is exactly what is happening here. Its not debatable since they are telling me, not trying to convince me whats right or wrong.

Yes, I think dealership wants about $5500 for winter wheels and tires; installed; with limited selection of wheels/tires. where else cost no more than $2500 for tires and wheels style we wanted.

good luck with that, our dealer wont consider that, even if we purchase the new 20s wheels from them.

[dream54ing]

After a long chat with dealership's tire specialist, theyve confirm the tires size wont cause any issue or void warranty. only thing would be the odometer will be slightly off since its about 3/4" taller.... So we eneded up ordering a set of 265/50/20 Nokian W4 tires from discount.
