I go back and forth on this. Would like truck to look more aggressive, love the look of off road trail but with the stock hwy tires looks frail. 265s in an at or mt would help.
pics? thoughts?
I'll x2 joneseyyy's comments here, pretty subjective choice... we're talking about a ~1" difference in overall tire height and ~13/16ths (20 mm) difference in width...That said, I put 285s (GY Wrangler Silent Armors) on my stock 2010 TE after ~ 1k miles and aside from having to move/cut a little plastic (which is no big deal), they've worked well. Now, do they look "significantly" better than if I'd put on the same tires in a stock 265 size? Well, I think they look better... "significantly" better? All in the eye of the key holder I guess... While the Wrangler SA's tread isn't super agressive, the taller sidewalls definitely fill out the wheel wells more (and I like that look personally, some don't...). From the rear I can tell the difference in tire width if I look closely, but 20mm wider isn't much. Just puts the outside wall of the tire a scosh further outboard without haveing to add spacers (which I didn't want to do).
All that said, I had the "+1" size tires on my old 3rd Gen Sport Edition (also GY Wrangler SAs) so I was used to both the look and driving performance/feel of running a slightly larger tire. While there may be some minimal differences in gearing, acceleration, on-road performance, etc, I've never noticed any significant differences while driving. Your gas mileage will take a small hit with the added tire weight, but it's a very small hit especially when you figure that any AT or MT tire will have more rolling resistance than the stock Dunlop "AT" (aka street) tires. I'll also say that I spend a lot of time driving for work, both in town and 2-4 hr trips, and the highway performance of the 285s has been great.
Next up for me is a set of 285 size Duratracs for winter. I've got 30k miles on the current tires now and while there's plenty of tread for another year of "3 season" driving, the tread is a little lower than I'd like for winter driving back and forth to ski resorts and backcountry skiing trailheads around Utah.
Last thought - I don't have any suspension mods on the truck yet but that's the next project I'm considering. At least a leveling kit to raise the front end up just a bit. Got to save up the $$ before I go too far down that road though.
Just my $0.02. I'm pretty sure it'll look great either way (once you get rid of the Dunlops of course) so good luck. And, you asked for pics so here are 2 of my truck - one with the brand new 285s on the stock wheels and the second of the same tires (after 30k miles) on my new TRD wheels.
