Anyone ever go up a tire size on their rear F Sport 18" wheels? 265 35 18?
If so, can you post a photo of your rear wheel/tire setup?
The tires I need are backordered nationwide for months and no availability is in sight. So i will be forced to go up a size. 265 35 18
The result is a .3" taller overall circumference. i can live with that as long as it doesn't look too weird. The width should be OK I am thinking.

Interesting. Looks pretty normal to me. Appreciate the pics. I ordered the tires. Lets see how they fit! I will post pics.
My question was not really will it fit or should it fit, it will. It's only 10mm wider and .3" taller. It's just a matter if it looks weird or not. I want it to look acceptable. Which per the above post, it would. I looked on the MFR website anyway to find that info and its not there. Tire rack too. oh well. The stock tires on my car tend to be a bit narrow giving it a stretched look. So maybe this could be a nice balance. I tried everything trying to find this damn tire in stock in 255.

Can anyone tell me the biggest rim size I can fit into these tires on my Lexus IS 250, I don’t know much about this stuff but I want to install black aftermarket rims.

I wouldn't go beyond 8.5. But i don't recommend that. you should not stretch tires cause you risk bead separation the narrower tire you use (for a given wheel) and plus you might damage your new wheels since the rim of the wheel would be exposed

Perhaps you should check the manufacturers specification for the tire first.............then comment.

You never go over OEM specs ! a professional suspension mod and tires shop don't recommend that, all tires must be the same for AWD, also Stretch tire and Wheel bearing is not safe, get a massive low offset rims and go 19-20 rims size !
Back in the day people need to be explained in person, the info is all over the internet Tires and rims website nowadays, go read

I went up (taller) to a 255/45/18 rears and 225/50/18 fronts on AWD due to potholes and snow rocks on the streets in the winter. Car sits about 1.5 inches taller. Ride is smoother, no rubbing, zero issues. MPH is off by +3 at 60, just factor that in. Car is 2104 IS350 F Sport.
I've been running similar oversized set-ups on all my cars (about 12) since the 1970's with no issue regarding suspension, steering, bearings, breaking distance (so long as you have excellent tires and break pads/rotors), ride smoothness, etc. Car is approx .1 seconds slower on 0-60 than cars with OEM size, but faster at higher end.
Not sure if the 265/35/18 works, the wheel gap (looks like a cavern) is pretty big on our cars, it looks workable. Your car will have a slightly wider and taller tire with the 265's, the question is to find matching height tires for the front.

Personally I wouldn't run custom tire sizes (and I know there will be many who disagree).
Increasingly, dealerships are denying warranty claims on differential repairs whenever the owner runs tires that are outside the manufacturer's spec / recommendation for that vehicle. They will categorize differential leaks/noise as "normal wear and tear" - customization voids warranty basically. Depending on the dealer they may or may not work with you on this type of repair. It's not exclusive to AWD cars, and it is not brand specific.
Differential damage typically doesn't show up right away, it just wears faster. Repair can be a couple of grand and if you're still running non-spec tires it will just happen again in time.
Even if the tires aren't the cause, it gives the dealership ammo to deny your claim.
