I'm planning on purchasing a set of 20 inch Ultra Goliath wheels for my 05 2500, no lift or level kit installed. Does anyone know or should i say reccommend a A/T tire size that won't rub at all? I tow a trailer for work so i don't want a thin sidewall, I want something with some beef. Any input is greatly appreciated.

 

1500 series owner here ('98 & now an '04) but my chart says that you can go 33x11.5 with the stock wheel on a 4x2 and 33x12.5 on a 4x4.
If the wheels you are getting have a back space of 4.5" then you can go 33x12.5 on either with no issues...
So in metric I'd say that's about a 305/55r20 would be a hair over 33" and about 12.5" wide.

So something like this:

305/55r20 Load Range=E,

• Radial Construction for High Mileage & Smooth Ride
• High Load Ratings for Great Towing Capabilities
• Self Cleaning Tread With Stone Kicker Rock Ejectors
• Siped Tread Lugs for Better Grip on Smooth Surfaces & Ice

 

Yeah, something around that size was what i was thinking off. Off hand do you know the cost difference between a BFG and a Micky?

 

Not off-hand, I've done nothing but Mickey Thompson or Dick Cepek tires on my trucks for better than a dozen years, spanning four different 4x4's, and have NEVER had an issue and have NEVER had a tire start to look even the slightest bit worn when I've replaced the truck. And up until about two years ago, I was as hard on tires as anyone. Not that BFG's are not a good tire, but my philosophy is that if it ain't broke...
Prior to that I've had cupping, belt, bad wear & other issues with other brands.

 

Thanks for your advice, I'm leaning towards some mickeys for my new rims. Just have to shop for the best price!

 

I had the older Mickey MTX's twice, once on a diesel 4x4 I used to tow a bass boat around when I tourney fished pretty heavy, got a lot of highway use out of 'em. Second set was on my current truck from about the time it was three weeks old until I lifted and went with Cepek FCII's in 35" flavor. I sold the MTX's with 29k on them, looking virtually new, for more than half what I gave for them new. I don't know whey they used the MTX label, because you'd think they were a mud tread, but they were A/T all the way, although they did good in the Ga. clay while hunting and working around the farm. The ATZ's replaced them a couple of years ago. They are not cheap, by any means, but if you get the wear out of 'em like I would assume you should, they'll end up being very economical over the long haul...
