I am looking at ggggetting some new tires, and moslt likely going with a set of the mckey thompsons ATZ P3. The only issue I have is what size to go with.

looking between 275/65/20 or 305/55/20 on the stock chrome rims.

I hAave the rough country 2.5 level kit, and it seems like the 275's will work baesed on other trucks recently.

Ideas? I drive my tuck 70 miles a day.

 

You'd have to go smaller than a 55 to squeeze those 305's in. Like a 50 series to make it not rub, but it still might rub.

And those tires are gonig to be LOUD, very loud compared to the stock tires. Those huge blocks will make tons of road noise and if you drive as much as you do, they won't last more than 20-30k miles prolly and have a good chance at cupping. Also looks like you can only buy them a LT load range D or E tire, which can make ride quality worse.

 

All of the reviews on the MT tires are great and they talk about low road noise and excellent life of the tire.

There are many giys runnign the 305/55/20 on the stock rims with no rubbing issue. I actually see the 275's being more of an issue.

 

My stock tires are 275/55/20s and with a level kit the 305 should work
