Hey guys, reviving an old thread here but I have a question about this setup.
The factory tire size on the LE 20" is 245/60-20 which is 31.57" diameter.
I have a 4th gen SR5 (just like the one in the OP) that I want to put these 20" wheels on.
My question is...would I be ok with 31.57" diameter tires since my 265/70-16s are 30.61" diameter? A calculator on 1010 tire says that it is a 3.16% diameter variance. Is that safe? They say that it may cause brake failure but I'm not sure.
That said the 255/55-20 is pretty close to the 265/70-16 in overall size. 31.04" vs 30.61" Only a 1.43% diameter variance.

You'll probably get better advice over on the 4th gen forum, but I think it might be okay rubbing wise? I've seen 265/70R17 on a 4th gen without much issue (which is pretty close to the 245/60R20).
However, I don't think you're going to cause any brake failure with the larger diameter tires though, at worst you'll rub while turning. If you don't care about squeezing in a taller tire, why not just get the 255/55R20?
i'm sure you'll be fine.. worst case scenario you just have to do minimal trimming or level out the front
