New Tundra owner- want to replace rims and tires!

Hi all,
I just bought a 2019 Tundra 4x4 double cab. I have had a 2016 4runner for the last 7 years that I bought new but need a pick up and I am excited about the tundra. Only downside is the tundra has the stock steel SR5 18" steel rims and size 265 tires. I had a lift kit on my 4runner with 285 BFG KO2's. Those tires got more miles out of them than any other tire I've ever owned. They were the E-rated ply and first set I got 70,000 miles on them til one hit a metal spike and got destroyed so I replaced all of them and 2nd set I got 85,000 miles on them which is a ton (almost 156k miles put on the 4runner since I bought it new and only 2 sets of tires entire time).

A few, potentially idiotic, new tundra owner questions as first step is replacing these existing street tires and plain rims:

- Can you swap from 18" to 20" rims without issue on the SR5 Tundra or do I need to stick to 18" rims?

- Will 285's fit on a stock SR5 Tundra without a lift kit or is 265 typically the max size without a lift?

- I already know the fuel economy on the Tundra is bad (as was my 4runner!!), but for those that switched from stock street tires to larger all terrains, did you see a hit on your fuel economy?

I'd love to get some black rims and 285 BFG AT KO2's on my tundra! I almost asked the dealership to let me swap out my rims and tires from my 4runner to the tundra but they are 17" rims on the 4Runner. I can live with 265's instead of 285's...not sure I want to put a lift on the truck right now. Pics of my beloved 4runner and the new tundra attached.

 

Congrats!

my 2019 came stock with 275/55/20. Some came with 285/55/20.

 

Welcome from LA (Lower Alabama)! You found the right place to get answers. Some more folks will be chiming in soon.

 

Yes you can put 17" through 30" wheels on your new Tundra. Most popular are the 18" or 20"

285's is a width, so it doesn't tell the whole story. 285/65/18 or 285/55/20's will both fit. 285/75/18 will rub without a lift. Too much width will rub, too much height will rub. Wheel offset will play into these combos as well.

of course the more aggressive, heavier and larger tires will negatively affect your fuel economy. As much as 5mpg depending on setup and driving habits.

Your 4R wheels were 6 lug and your new Tundra has 5 lug hubs, they are not compatible anyway.

Good luck with your search, lots of threads on here (a whole section actually) dedicated to wheels and tires.

 

thank you! 4Runner had 285/70/R17. 285/65/R18 looks to be just slightly smaller and would work nicely I think.

 

18" or 20" wheels will work fine. I bought my 2019 used and it had 20" wheels. I swapped them out for 18" wheels for more tire sidewall. As noted elsewhere, your Tundra wheels are 5x150. Factory offset on mine are +60mm.

285/65/R18 is 32.59" and should work fine with no lift. I believe that is right at the edge of what will fit with no rub on a non-lifted Tundra.

In my opinion, the Tundra looks way better with a small lift. In the 2" - 3" range.

 

stock sr5 suspension with 285/70r17 on rock warrior wheels, no rubbing at full flex.

 

Congrats!! I had 285/70/17 on my 2020 AG 4runner Pro. And now on my 21 Tundra Pro 285/70/18’s. I get between 14 and 16 mpg. About the same I was getting on my 4runner. I have a new set of SCS wheels to go on in the spring. Love to put 35’s but don’t know if I will. They look good but I drive my tundra every day now so maybe not.

 

I may do a lift at some point but probably going to hold off for a while. thanks for the insights on tire sizing though for the tundra- very helpful!

 

that looks great!! Good to know that size will fit!!!

 

That's about what I would think the MPG would be with the larger tires. I averaged 15.2 MPG in the 4Runner but the full roof rack also impacted aerodynamics. I'm looking forward to a much quieter ride and having a pick up again. 285/70/17R was what I had on my 4runner and I liked that set up. May get with the tire shop to see about 285/70 or really may just go with 285/65/18's.
Thanks for your insights!

 

Hi All,
I have a deal potentially lined up with 18" "Ultra Motorsports" rims. They appear to be aluminum alloy. Seller says they are Ultra Motor Sports as the manufacturer but not sure of the model. Based on my quick research they appear to be the Gauntlet rims shown here: https://www.tirerack.com/wheels/ultra-gauntlet-black-painted
Seller tells me the bolt pattern is 5x150 and they are advertised as fitting the Sequoia, Lexus LX470, FJ100, and the Tundra. I have a 2019 Tundra double cab 4x4 I just purchased and finally picked up this afternoon from the dealer that took it in on trade. The rims come with 285/60/R18 tires but they are mostly street tires and not of interest. However, the price is pretty fantastic and rims alone appear with more than he is asking ($400 for rims and tires).
Anyone know, based on the specs noted here, whether these will fit my 2019 Tundra double cab? Anyone have experience with these rims? Online reviews appear to be very good. Thanks in advance for any help/insight!

 

I put 200K on rims like your old ones. FINALLY replaced them with lightly used TRD offroad rims. Amazing difference fairly cheap. Of course there is always the lug nuts and the TPMS to deal with.

 

Those wheels should fit fine. 5x150 bolt pattern +25mm offset which many on this forum consider to be the “sweet spot” for our trucks. If you don’t plan on lifting your truck now or yet I’d get those wheels then look at a 275/70r18 all terrain tire. Will fill out the wheel wells some and look pretty great at +25 offset. (Hundreds of threads on this forum about the top 5-6 AT tires).
You’ll probably have to remove the front mudflap (on the front of the tire) and do some fender well heating and moving. Maybe some skid plate trimming. But you’ll be very happy with the upgrade from those gray steelies.

Plus you can run winter tires on the steelies or sell them for $100 or so depending on your location for someone else to run winters.

 

OEM size for that truck (if equipped with 18” wheels) would be 275/65-18. It’s ~32” tall and a fuzz over 10” wide.

Most common bump in size for stock suspension is probably a 275/70-18. 33” tall, and really close to same width.

A 285/65-18 will be about a half inch taller and a little wider than stock.


Fitment of any of these sizes will be a walk in the park as long as you have wheels with some respectable offset. I’d look for +18mm at the absolute minimum, but prefer to be in the +25mm to +35mm range for less rubbing opportunity. Any zero offset or negative numbered offset is not your friend unless you like big lifts and extra suspension wear.

As mentioned, you will likely need to remove the small worthless mudflap at the front of wheel well. You may also need to heat up and push the fender liner forward a hair. Don’t worry, it’s easy. At the rear of the front wheel well, you may need to use a Dremel to trim the lump on your mudflaps. Easy if you mark them and remove for trimming. Likely no need for any body mount alterations, but it’s always in the back of my mind!

If the inside of your tire rubs the skid plate at full lock, I don’t recommend cutting it. It’s easier and less sharp edged if you simply hem the skid plate wings. By that, I mean to fold the edge up and squish it flat with some Channel Locks. It’ll trim out nice and won’t cut the ever living fuck out of your hands when you’re down there…. Remove the skid for this and do it on a bench. Much easier to make it look decent and less hassle.


Good luck on the new Tundra. You already know you’ve made a good choice.

 

Thanks all for the very helpful replies. I hope to pick up these new rims in the next day or so. Gonna look nicer than the stock rims I think.

 

I just wanted to say thanks again for the input given on these new (to me) rims. Picked them up last night and got them installed this evening. I like the look of them a lot better than the stock rims. Have some temporary 285/60/R18 tires on there...going to shop around for some new all terrains though. I am not going to go with the BF Goodrich AT KO2 load rated E I had on my 4 runner as I don't want to sacrifice my ride quality so much on pavement so will be looking around at alternate tires...probably go with 275/65's or something like that. Pics of the new rims attached. And for future reference, should someone be searching, Ultra Motorsports "Gauntlet" 5 lug rims fit the 2019 Tundra perfectly! Stock lug nuts won't work though due the the deep recess of the wheel @ the lug nuts so you need to get spline lug nuts and the key that goes with them to make it work. Also a breaker bar and key to be able to change a spare as the stock lung nut wrench won't fit.
