Alternative tire size from 265/45/20

I currently have 265/45/20 tires and wondering if there are any issues putting 255/50/20 on to replace OEM size. I would like a little more sidewall because I live on a dirt road. I know the speedo will be slightly off.

You may can fit 265/50/20 and they make more tires in that size then the 265/45/20.

You may or may not fit the 275/45/20. I think it's possible.

Has anyone tried 275/40/20 size on these wheels? i currently have 255/45/20. I like them but wish the side wall was tiny bit less and wider tire would look so cool, i think. The tire in picture is nearing its life so sidewall is good now but i wish it was like this when new.

The best size and the most comfortable and ground clearance wojld be 275/55/20. At least I am going to do this setup this summer when I install new tires.
Also, I do drive a lot on gravel roads and even on the highway the 265/45/20 is too loud and rough. I hate those thin tires.
when I get tbis setup if they dont fit ( i am pretty confident they will), I will either get spacers or get a different offset - probably a + 43 wheels. Currently I believe theyre +61 so bringing them out about 20mm will be perfect.
Either way, play with tiresize.com a little bit and it should give you an idea. Below is an example.

Also, go to discount tire and they will test fit tires for you for free.

You’ll be fine. Speedo will read a tiny bit low, but the extra sidewall helps on dirt. Just keep all four the same size. No rubbing issues on a GLE.
