New member - new lift/tire journey...

Hello - just joined and have been digging thru a bunch of suspension and tire threads for a while.

I'd like to hear some good common sense/experiences based on what I'm doing with my setup.

I bought a new 2021 TSS 4x4 about a year ago.

Installed a ReadyLift 3/2 kit, running on the stock 20" TSS wheels and tires (275/55 GY Wrangler DT)

I want to get a little more wear out of stock tires before i change them, but i'm looking for some input on what size i should move to next, in terms of height, width, possible spacers, while taking drivability and such into account.

So my questions are -

1) Should i stay pretty close to stock width? i.e. I dont see much to be gained by going to a 285 or 295 with the risk of rubbing on the inside

2) What is the sweet spot for height on this setup? I'm thinking something around 34" would be a nice compromise between appearance and livability, but i really don't know.

3) instead of a wider tire, would a 1.25" or so spacer give me a nicer stance without causing a whole lot of rubbing? (taking a taller tire into account?


In summary, I did what any self respecting nerd would do and built out a spreadsheet of common tire sizes in this ballpark for comparison....but i'm just not sure:

275/60 ....about 33"
275/65 ... about 34"
285/60 ... 33.5" and a hair wider than stock
285/65 ... 34.5" and wider...might be pushing it
295/60 .. about 34" but a bit wider
295/65 .. 35" and wider....possibly too much.


Comments most welcome!

 

I did a bilstein lift, about 2.5” front and rear. Stuck with my 18” trd off-road factory tires(for now) and wanted a narrow, taller tire. I went with a 285/75/18. Initially only rubbed on the skid plate(I replaced it for an RCI) and the mud flap(heat gun fix).

Also wanted a wider stance so did 1” spacers(if I had it to do over again I’d have gone with the 1.25”). With the spacers I rubbed on the front bumper, so added a .5” bumper spacer.

I realize the 20’s will be different…I personally prefer more rubber when possible for off roading. I’ve really liked the tire size I went with, the narrow tire is great in the snow and on trails. I don’t see too much sand so no big issues there.

Hopefully some of that was helpful.

 

Here's mine on 285/65/20 and I've got the Rough Country 3/1 1/2. No rubbing issues at all on stock 20's.

Thanks for the welcome, and the info! It sounds like 34ish won’t be a problem.

So…I may go ahead and do spacers while I’m waiting on some tread wear on the stock rubber. What do you guys think about 1.25 vs 1.5 vs 2”? Particularly keeping in mind that I may end up with the altered geometry of larger and wider tires and whatever effect the spacers may have on rubbing once I get new tires.

also…I don’t want it to look terribly awkward, so I’m thinking 1.25 or 1.5….but I’ve also read people regretting not going ahead with 2”…

 

In my experience more than 1.25 and you’ll start to get a lot of tire kick up debris on the side of the truck.

 

Any experience with the KSP brand on Amazon?

don’t wanna skimp but where’s the sweet spot?

EDIT: i think i'd feel better rolling with something proven like spider trax..

 

Did you reprogram the speedo and such?

Welcome to the forum!

 

Nope

 

Adding spacers is more likely to lead to rubbing depending on size. I assume your TSS wheels are a +50 offset (different than other Toyota Tundra factory 20” that have a +60)…Look on the back of the wheel. It should be stamped into one of the spokes. If that is the case…285/60R20 will fit easily with no issues (basically a 33x11.5) with a 3/2 lift. 295/60R20 is likely the max on that offset without spacers; depending on tire choice a 295/60R20 will likely have some minor plastic rubbing or need to remove front mudflaps. Keep in mind manufacturers tires are not all the same height/width despite being labeled the same 285/295 33/35 etc.

 

I just can't get behind spacers. I would rather buy the wheels with the offset I need. But If you are sticking to stock wheels, wider tires on narrower wheels (that fit, are recommended) look way better than the opposite.

 

One of those, stock rims, no spacers.

Welcome to the Tundra forum... We likey pics here....

Best I can tell the stock TSS wheels are indeed 50 offset

So after ingesting the info on this thread, i'm thinking no spacers and 285/65/20, given that i'm most interested in height not width. Hopefully no issues...

Do I bother with a programmer to update the ECU with new size?

 

Only if it bothers you that data is off. My truck is very happy with the bigger tires...

You should be fine with that size.

if you’re more concerned with max height than width…I’d go 295/60R20 or 35x11.5R20 (Nitto/Toyo make this size). 285/65R20 vs 285/60R20 are going to essentially be the same height the 65 & 60 are a width measurement

I put Nitto Ridge Grapplers in 35x11.5R20 on my TSS wheels (+50) offset with a 3” from lift (rear is a non-issue, but was at 1.5” for reference) - cleared UCA w/o issue; no BMC needed, no rubbing after removing the tiny front flap on the front fender endcap and alignment completed (alignment because it’s needed- didn’t have rubbing pre-alignment either)…the 11.6” width of a 295/60 is the widest you’ll want to run without changing to a different offset or changing UCA

 

Backwards. 285 is the width. 60 and 65 are the ratio of tire section height to width.

 

Yep. The 285 65 will be taller same width as 285 60

 

My mistake…you are correct…damn metric sizing lol.

i knew there is in relation between the two…that’s why I was thinking the 295/60 would get him more height than a 285/60…but a 285/65 would be similar (just slightly narrower as you’ve called out)

 

So just to beat the dead horse one last time to summarize:

if I roll with 285/65 (roughly 34.5”) on stock 20” +50 wheels, I should expect no rubbing on spats, fenders, control arms, etc?

 

This is my truck with 3” up front 1.5” in rear with 35x11.5R20 ridge grapplers on tss wheels…discount tire asked me to remove the front mudflaps before bringing it in…I re-installed with no rubbing afterwards. Not the best picture of the front, as this was temporary until my new wheel set came in. Stock upper control arms no body mount chop, no liner rubbing…Ironically, I actually rubbed at the front when I changed to a +10 offset on the new wheels before changing to an aftermarket bumper because of the further out stance.

 

This was my truck on 285/60R20 (33x11.5) same tss wheels, no clearance issues

 

You won't on the fender or control arms. Very, very likely you won't touch the swaybar either. If by spats you mean the mudflaps, probably not... but no big deal to remove if you do.

People who are familiar with how the Tundra is aligned know that there is a decent amount of fore-aft wiggle room, depending on how it's done. Your resulting clearance might be different than someone elses for that reason. Your +50 rims are perfect for maximizing clearance with narrowish tires anyway.

 

Your truck looks amazing. This is EXACTLY what I I've wanted my 19 Limited to look like since I bought it.
