So we get 255/50-20 tires from the factory. Some opt for a 265/50-20, and some opt for a 275/45-20 as well. Is there anything else I am missing size wise?

Whoever owned the truck before me lowered it and didn't keep an eye on the alignment. So the perfectly fine General Grabber's I have need replaced. They are the 275/45-20's and I like the way they look. Ride could be better, but I'm sure that's more the suspension vs. the tires.

So what is the advantage of the different sizes? Is it an availability option, or a looks thing, or are you guys going for better performance?

It looks like there are way more options for the 275/45-20 tire, but they are more expensive.

Any of those three sizes will work. 265/50 is a little taller and 275/45 is a little lower then stock 255/50.

You wont be able to get grabbers again. I can recommend the two types of tires I have run which are BFG KDW2s or Toyo Proxes ST 2.

I had the Toyo's on my last truck and they were real nice. :coolthumb:

I have bought tires online the past three times, but I think I will be going local this time. Tire Rack & Discount's prices arent that much better after you pay to have them installed.

I think he meant to say 275/45-20 not 275/40-20 The 40 will be shorter yet from the 45. The only tire manufacturer I know that has taller than stock 45 series is the Aturro AZ800 which is 30.4" tall-stock being 30.1". And most 275/45's are in the 29.9-30.1 range... hope that helps ya out.

I'm probably going 275/45-20's, but I am always open to see pics of new size options too.
