5-door (year 2024) experience with 215/80/15?

I've been browsing the internet quite a bit and I can't find much information, anyway, I apologize if the subject has already been discussed.I'm about to receive my 2024 Suzuki Jimny 5-doors and the only modification I plan to make is to add some more off-road tires. I've read and researched that the 215/75/15 tires work well with the stock vehicle, but I'm interested in the height gain that 215/80/15 tires would give it.My questions:I know that compared to the OEM size, the 215/80 profile adds 32 millimeters (+5%) to the overall diameter.I also understand that the 215/80/15 profile fits, but I want to know at what cost.It could cause me problems in the future, I mean wear on gears, friction with some parts or any problem that could lead to putting on 215/80/15 tires.If anyone has experience with these tires, please let me know if everything is fine or if you definitely don't recommend them.Thank you very much.

215/75r15 is a popular size for Gen 4 and there isn’t much difference in 215/80r15, just slightly bigger, see tyre size calculator

tiresize.com/tyre-size-calculator/

Clearly your speedometer will change to under-read, but then they all over-read in the first place. It will be slightly higher geared, but that will hardly be noticeable.

What you might notice is the increased tyre weight and a small drop in fuel efficiency, but these won’t be too bad and easily outweighed by the better tyres for off road.

Plus they will look cool in your wheel arches.

My concern would be that all the tyres in that size seem to have a 102 or higher load rating, so they're going to be very stiff, as they're designed for heavier vehicles.

I say do it and don't worry about the load rating 
My yokohama G005 have 115 load rating and work just fine

The load rating is not the issue, the weight of the tire is the issue, and that has a negative impact on braking - a lot of people won't recognize this until it's too late.

I own both the three & five door Jimnys, the three door is on 215/75R15 ATs, the five is on the OEM Bridgestone195/80R15, I've no experience with 215/80R15 on either vehicle, but I do have experience running larger tires on a variety of other Suzuki models.

215/75R15 is about as large as I'm willing to run on a Jimny, 215/80R15 is approaching the limit that I consider acceptable without re-gearing, I would not want to run that on a three door without a brake upgrade, on a five door you might be able to get away with it.

The braking and tire weight is not to be taken lightly when modifying a vehicle.
I have had many Suzukis with too large tires up to 325-60-15 or more normal 31"s on my SJ wich have more or less the same brakes as the newer Jimnys.
Running 235's on my current Jimny. upgrading to the vented discs has a good impact on heat dissipation and has been a good mod for me driving many long and steep hills in Norway. (With a trailer.)

All in all I think the jimny can take larger tires but as with other mods and their combination one must consider the whole picture while modifying a car.

My mate put 36" tires on his Heep Cherokee and it could not at all brake good enough after that. He had to buy Hydro-assist brakes for it.
Thinking in horror every time I see a jeep with large tires now, not knowing if the owner have just thrown them on or done a proper job modifying.

Not so scared when I see a Suzuki on 30-31".
