265 or wider tires on stock 18x7,5 wheels- 4Runner TRD off road

[ssapaj]

Hi guys!
I wanted to upgrade the stock 245/70/R18 tires to 265 or 275, keeping the stock wheels, but I’been researching it’s not safe, since 245 is as wide as a 7,5” wheel can safely take. What do you think? I’ve been reading here that people is doing it on the SR5 r17 stock wheels, without any issues (like rubbing), buy I’m afraid it may not be safe long term or for highway speed.
Thanks

Well, I'm about to upgrade from the 245's to 285/70/17's. I ran the same tires on stock rims on my 5th gen without issue.

My Off Road Premium Hybrid is 265/70R18 stock (black wheels). Yours are 245? I just put on Falken Wildpeak A/T4W of the same size as stock. I know this doesn’t help you, but I was surprised to read 245 tire width on yours. Anyway, this is how it looks with 265/70R18 Wildpeak A/T4W’s.

Thanks! Looks great!
I’m not in the US. Toyota sells with different specs here (Chile).

How is the road noise with the Wildpeak A/T4W’s and did you notice a MPG hit ?. I'm thinking of those tires or going a little bigger @ 265/70/R18

Did you go with the E Load (LT265/70R18 124/121S E) or SL load? (265/70R18 116T SL). Looks great.

Just picking one example, Toyo A/T III specs say that a 295/75R17 will fit on 7.5" wheel. Now at that diameter (34.4") and width (11.6") you will need to remove air dam, bend back tab and remove crash bracket - and on SR5 it might still rub, but you certainly could go 285/70R17 (33" dia/11.5" wid) without issue.
Note that the Offroad trims all come with 265/70R18 which is 32.6" dia. Many folks here have put 285/70R18 (33.7") on these trims without mods and no rubbing. I strongly suspect this will also work on SR5 but can't recall for sure if someone has done that (since they come with 17" wheels, and folks who go aftermarket often go to 17" anyway). FYI that I run 285/75R18 (34.8") - no rubbing with 1.25" level kit after crash bracket removed on +45 TRD flat black option wheels.
BTW: Offset matters! Keep your +55 offset wheels to maximize tire diameter.
(I think I've covered all the bases but do you have 17" or 18" wheels? you mention both above and if you have lower offset 18" (e.g., TRD PRO +20) then adjust down a size from what I said - or get a lift.)
