so learning as I go.

what I see so far is the stock 275/45 is 10.8 inches wide and 31.7 inches tall.

your 285/45’s are wider at 11.2 and taller but not by much at 32.1. Thus you have 0.2 inches more sidewall for off-roading etc.

here from calculator:





Meanwhile the 275/50’s are the same width as stock at 10.8 (negating rubbing?) yet are a full 1.1 inches taller, meaning over a half inch more sidewall. This should mean there is roughly a half inch more tire all around. It looks like it would clear but I haven’t really crawled around under there yet. Just got car today.…

 

I think the rubbing is not only due to width, it would also be influenced by height of the tire. It grows half an inch top and bottom, but also on the sides, where it might start rubbing on the liners. I might be totally wrong though and would be delighted if anybody take it to test and prove me wrong.

 

My experience with a 2024 110x was the wider / taller you go in tire size, with no mods to the vehicle, you could run into problems with rubbing on the upper and lower control arm pivot point (see attached photo). With 284/45/R22 Toyos I have about an inch of clearance vertical and horizontal, and have not experienced any rubbing yet. With a 50 sidewall on a 22" rim, this could be an issue I imagine. This would not be a problem with a 20" or 19" rim.

 

If I wanted to run 22's I would break out the grinder and do a nice smooth radius on that upright with a 15mm spacer..

 

this is interesting nice job. And a lift wouldn’t help…. I’ll try to get in there today and look around.

 

Don't lift it if you want to drive highways and twisty canyon roads and don't put all that crap up top to totally screw up your center of gravity and your handling on the hwy..

 

I've had my car with and without the lift and have to say that for offroad applications in the highest offroad setting the ride is considerably more harsh if you are using the lift rods. You feel every bump against your spine. When not using any lift and using the OEM rods, the ride feels much more plush and controlled.

 

Ok I’m hopeful this will work.

in the Johnson Rod thread there is a fellow with 275/60/20 tires and said no rubbing. His tires are 33 inches.

My plan (275/50/22) shows 32.8 inches. If his clear the control arm pivot point, I believe mine will too. It’s not great science but currently my hand fits between tire and the closest part of potential touching, which is more than an inch thick, so an additional half inch should work….

hope to swing by tire place this week

 

Just a heads up:
Using those tire size calculators may not produce the exact dimensions of the tire you’re interested in. I always use the tire manufacturers web site to get the detailed specs of the tire/size I’m interested in. A 33” tire for example, may vary by half inch or more depending on manufacturer, size, and even load rating.

 

Good idea. This was done using manuf websites:
