I have a 04 1500 5.7 4wd Slt Quad Cab and I was wondering what size tire I should get next time around, the truck has New Shocks and bushings not really looking to do a lift kit at this time. For the most part the truck sits kinda level slight rake to the front. Thanks

P.S Leaning toward BFG or Nitto.

Use this to determine the differences between sizes.

Can i use the 305 on a stock rim with no level kit and no spacers?

What is your stock size?

I believe 275/60/R20 is stock size

How much difference is there really looks wise and size between the 305/55/20 & 35 12.50-20, They both are about the same price, which would be the better one to go with?

What are the load ratings for them? Nitto? If I recall, when I was looking for tires last year, the load ratings were different for those in metric vs. those offered in standard notation. You don't need a HD-rated tire if it's just going to be a daily driver with occasional loading, towing, or wheeling. Those will be a much stiffer ride, and a heavier tire.

I am not sure that is something id have to look into. How many ply is a LT tire? More then a non LT tire?

What size/width are the 06 and up 20 Inch rims?

Well I know I asked this question a while ago But I finally replaced my tires, I ended up just going with a Stock size 275/60/20. I went with a Toyo Open County AT 3. So far I am very happy with them I have about 5 Miles on them lol. If I was going to change the rims I probably would have gone bigger but for the amount I use this truck I just didn't go that route.
