and if i had to trim what would that consist of?

 

you dont want wheels that wide. for those tires you want to have something 7-9 inches in width.

 

^^agreed, your stock wheels would work perfectly with those tires but if your set on aftermarket just stick to what NVANZEE said and go with a wheel between 7-9" wide and i would try to stay at the stock 6"BS.

 

You are gonna wish you went with a 5" backspacing, especially if you do decide to go with wider tires later on. I am running 10" wide rims with 31-10.50s without any problems.

 

you may not have any problems running a 10.5" tire on a 10" rim, but the recomended rim width for a tire that wide is 7-9".

 

I had 8" wide wheels with 6" of backspacing before these but they were just too narrow and tucked in for my taste. I have run 31-10.50s on 12" wide wheels before but all-terrains start looking a little go kart-ish at that point.

 

i understand that 10.5" tire may work on a 10" or 12" wide rim, but i like to take the safe route when giving advice so someone cant come back and say hey you told me this and now it f*cked up my blazer.

 

Yea, I here ya... Of course anyone taking advice from us will hopefully mix it with some common sense... I mean, we could be psychopaths or something! lol

 

lol

 

lol ok im guna go with 5 or 6inch of backspacing on a 10in wide rim with 31x10.50s..im not worried about having to trim at all i do have a litle bit of common sense when it comes to this stuff i just didnt know what was the max size i cud go with rims n stuff
