If I go with 17s, was thinking about running 285/70/17. This should be 32.7" tall and 11.2" wide? Similar to my factory 275/60/20, should not need to change speedo or and suspension.

 

If you're interested, I've got 17"s on my ram with new Michelin LTX A/T2 tires that I'd trade you for your 20"s. Size is 265/70-17s. They also come with a warranty and everything.

 

If the tires were bigger I would trade with you. And it would be easier since im in Tampa

 

i live in Alberta where there is plenty snow! I have 20's and haven't got stuck once in the 3 years I've had the truck. It's tires and how you drive.

 

I don't see the logic in thinking they have worse road traction- if anything, they are better than smaller rims in a general sense on the road (snow, or otherwise), and for the same reason they are much worse off road..

it's all about sidewall, pressure, volume of air and conforming to terrain off road.. the taller sidewall can deflate more, and has more surface area to conform to the shape of say, a rock, a log, and they can increase 'footprint' in mud or sand- which means they displace the weight of the truck over a larger surface area as well as increase footprint for traction...

on the road, shorter sidewalls allow for less lateral movement and stiffer performance while cornering.. the contact patch doesn't give as much, which means the suspension doesn't dive as much, which means your line can be more precise..

but let's face it, we're talking about 6K#+ trucks here.. low profile sidewall performance? really? it's more... for looks.. Off road (higher sidewall), it isn't about looks at all, it's about performance, in that you're less likely to get stuck..

in snow, the tread is about the only part of the tire that matters.. and the firmer, the better to bite into the pack or ice..

 

Yeah I don't see that 20" wheels are a big detriment on pavement and should perform better than a smaller wheel during hard cornering, but then again, you shouldn't be hard cornering in a truck or high SUV. Short of the weight wearing on front end components a bit faster and hurting fuel economy a tad, I really have nothing against larger wheels on the road.

It's off-road where you want all the sidewall you can get...
