got a question about a wheel size

I am about to order my wheels.. I am a little confused on which one would fit the best. They are the KMC Hoss 20" now there are 3 different ones I can order. They all are 20x9.. 1st one: it has a neg 12 offset and 4.53 backspace .. 2nd one: +18 offset and 5.71 backspace and the 3rd one has a +30 offset and a 6.18 backspace.

Also I picked out tires too just not sure if it would be better to get the Nitto Terra Grappler in 285/50R20 or LT285/55R20 or is there a better size? Now I do tow a boat so I need a tire that can hold up to long tows.

I have a OEM 3" kit on order too. So I am hoping it all fits with no problems.

Thanks for all the help I am seriously a rookie when it comes to this.

Thanks

Rich

 

I agree, Get the 4.5 bs wheels and get the 285-50-20's.

 

First or second one, depending on how far you want your wheels to stick out from the fender?
