I have 18x8.5 rims i wanna do 235
In the front but can i do 275 in the rear if not what can i do

275 is fine

The minimal rim size for 275 is 8" so 8.5 would be far more then just ok

OP....here is my suggestion. Compile a list of the tire sizes you are interested in buying and their manufacturers. Then go down the list and call each manufacturer and ask them if that size will work for your wheel. That way you are getting accurate information directly from the source of the product.

I went through this same thing with tire sizes for 6 months and I will tell you that all of the forums, not just ME, are full of misleading information regarding "safe or approved" tire sizes for specific wheel sizes. After all was said and done I have 275/50-17 on 8" wide wheels on the rear and it is absolutely fine. Not one problem and they ride and handle great for daily driving.

Just my $.02.....

Yup! +1

Here's 265/40/18 on 8.5 rim

So just get 275/45/18 and your good

Not sure where you're getting this info or which tire brand you're proposing, but most 275's require a minimum of a 9" rim. Here's the specs right off of Nitto's website for their NT555 in a 275/40/18 or 275/35/18 or 275/40/17. They recommend a 9.5" rim for best fitment, but "Okay" as small as a 9" for this particular tire.

Ya on a 275/35 or 275/40, it's easy to make point when you only show stuff that goes along with what you say, why didn't you post this
Op never said he wanted a 35 or 40 tire


And a 275/50 is a minimal of 8"
275/45 is a minimal of 8.5"
