Yep, stay with the same size and bite the bullet and get the Michelins!

Genuine made in USA Cooper Discoverer H/T tires installed all the way around, $640 after rebate.

Road real nice coming home from the shop, like a new truck. I think the shop screwed up and installed the next grade up, because the final bill was $44 more than we agreed on, so they adjusted the price (after some hassle with the computer) and away we went.

The shop was understaffed, however, and the job took about 3 hours.

Would love to have gone Michelin, but $1150 for tires, admittedly very likely the best tires on the market, is out of the question. The previous set was rotated every 5000 miles and kept inflated at 42 pounds (slightly over pressured)

These Coopers came highly recommended, and my internet research gives me some comfort in my decision. If they truly suck then I will post on this and some other forums to that fact.

An engineer friend once said, "One good test is worth a thousand expert opinions."

So now we will see.

Stay with Michelin, you already know you are happy and safe with them. I never even considered any other tire for my truck. Went straight to Discount Tire and replaced the old Michelins with new ones. Discount Tire normally has sales and rebates, should be able to get out the door for $900. Keep checking, wait for a sale.

Size is 265/70 17" over the original 255/60 17" making them 1.5" taller. This offsets the speedometer by 5%

The load range is 115 over the original 108. (you can find charts to translate this online.) Stamped on the side of the tire it says Max Load = 2535 LBS.

And I got chrome valve stems to boot! Whahoo!

It will actually have Load Range D or E stamped on the side of the tire
How many Plies are the tire?

I bet by going that much bigger the ride feels mushy compared to what it did before right?

Going 1.5" over stock is not going to be a good thing but you will see when you try traveling over hills and slight inclines the tranny will keep shifting - better have a good tranny cooler on the truck.

Also with the bigger tires and the speedo being off you forgot to factor in the ABS - I know when I went to 35" tires (2" over stock) when I would hit my brakes - it seemed I had to hit them harder to stop - hopefully that isnt your case.

Might be a good time to invest in either having the dealer reprogram your Pinion Factor or purchase a programmer like superchips to fix this so when you are towing it doesnt become a real issue.

I only talk with experiance on this subject because I have been thru it - now I want to jump to a 33" tire to put me back in my stock range versus what I am at now.

My son works at a tire store and says the Coopers are a good buy and they see few problems with them.

Your ABS shouldn't have a problem if you all the tires are the same size, even if you go up or down in size. The speedo will be off, however. I don't know how much the dealer would charge to tweak the speedo, but I picked up HPTuners last year. It lets you fiddle with all sorts of stuff, including trans line pressure, shift speeds, shift firmness, gear/tire changes, fuel and spark curves... Its pricey at $500

And yes, taller tires are like shorter gears, and make the brakes less effective, too. Not to mention increased rotational mass.

on topic, I've had good luck with BFG All Terrains. I picked up another set a few weeks ago, stepped upto the load range E, and right at $1000 OTD for 4, with the works.
