285/70/17 or go to 18s on TRD OR

[Jeff11]

I want to get bigger tires. Already did 2" lift. I currently have the stock 17" TRD OR wheels and tires. I'm stuck between going to 285/70/17 and keeping stock wheels (for now), or get a set of TRD pro 18s and go either stock 32.6 tire or even step up slightly to 275-70-18.

I know gas mileage will take a slight hit. But I don't want to totally wreck it. And I'm looking for good drivability on road but also great capability of road (not really anything like rock crawling). The 33" tires for the 17s seem to be a bit heavier than those for the 18s, even in SL.

Then again, if I lose 2 mph going to 33s on 17s, that's still a lot of time driving before I lose the amount of money it would cost to purchase new 18" wheels lol.

What are everyone's thoughts or experiences?

Thank you!

I just went through this. I decided to pick up a set of 18” trd offroad wheels and go with 265/70r18 Wildpeak AT4w’s because I didnt think I wanted a 285 wide tire. They are pretty beefy in the 265 width.

In hindsight I wish I would have stayed with my stock TRD OR wheels and gone with a lighter 285/70r17 tire. Probably something like a Yokohama Geolandar g018 or Nitto Terra Grappler G3.

Both for having a lighter tire and I think they would have looked better.

Yeah I'm thinking of staying with 17s and going 285/70/17 in a SL rated tire. Something under 50 lbs. I am between the Nitta Terra Grapplers or the Toyo Open Country AT3s.

The 265/70r18 Wildpeaks I put on are sl’s and weigh ~50 lbs and I can absolutely feel the weight, especially starting from a stop. They arent bad, and should be great on fire roads and gravel roads in the mountains, but they are noticeable around town.

I dont think it was a bad choice, but if I was to do it again I would have gone 285/70r17 in one of those other tires. I did consider Toyo at3’s as well.

I stayed with 17’s. RRW’s with Nokian outpost NAT 285/70r17 (46 lbs) barely noticeable drive ability, Amrid (Kevlar) reinforced sidewalls, and about 1 to 1.5 mpg hit. Total weight per corner is 71lbs with steel protection rings.

Great setup! How do you like those Nokians? Also, is your mpg hit according to the dash or your calcs? The speedo is off slightly now with bigger tires so you might actually be getting the same mpg but the truck thinks you've gone less miles.

Hand calc. 285’s make the speedo dead on!

Oh that's awesome. Toyota probably figured we'd all throw 33s on anyway
