Larger tire size

Just went up next tire size to 275/70 R17 on my 2020 TRD OFF ROAD PREMIUM. Any info on premature suspension wear or problems also wondering if it affects the warranty?

 

You're good. Nothing to worry about. At all.

 

Thanks, I probably should've confirmed before hand but that size in falken wildpeaks has her looking like a beast.

 

I would say that we cannot say it would have zero effect on the life of the suspension and related components. Depending on how much extra weight added with the new tire you should expect little less life out of your suspension but on the other hand depending on the tire you got you will gain little more ground clearance, much stronger tire for your needs like in off road conditions.

Update -

Here's the theory behind it. But many of us run heavier and/or lager tires

If you apply this theory to yours, we are looking at old 40lbs x 2 (80lbs) vs new 58lbs x 2 (116lbs) each corner. Again its all theory. All I'm saying is suspension and related components have to work little extra. So theoretically if something have to work extra we cannot expect the same life right? Again just shared for any one to learn and not saying its going to fail very soon because of this little mod. NO..

 

Well tie me down and beat me with a feather

 

We like pictures!

Oversized tires are pretty common around here. I haven't heard much, if anything, about premature failures due to it. It's still worth checking things periodically.

I had mine put on a lift recently to check on the ball joints and bearings. Everything checked out ok, but I'm glad I checked. I have 67K miles on it. 29K Stock with stock size KO2's, 38K lifted of which about half was on 285's and half on 295's.

I think how and where you drive will have the biggest impact on the life of your suspension components.

 

fwiw the faster you burn out your current suspension you can upgrade to a new suspension.

Also I am running 285/75/17 and haven’t had trouble yet. But again I don’t have a ton of miles on them yet.

 

30k with the stock tires and 25hrs with the 275/70 r17 wildpeaks

 

I ran one size larger on my 97' Tacoma, can't remember size. Stock suspension, no lift for 261,000 miles and never had an issue up front.

Had a couple of leaky stock shocks in the rear and the infamous broken leaf springs, but that wasn't due to the tire size.

 

Well I ordered 35s for mine so hope I’m ok hahahahahah

 

How is stopping distance changing compare to stock tires? On wet? On highway speed?

 

It definitely takes a little more pedal to come to a full stop and get going again, but it's not enough to sweat over. I did drop about 1.5 mpg on hwy from 19.1 to 17.6 which in my calculations is about $800 over the life of the tires in today's gas prices (FJB). At highway speeds in a down pour it definitely felt more planted.

 

I have no empirical evidence to say yea or nay, but it would seem to me that Toyota would not have engineered the 4R suspension's ability to last to be completely dependent on whether users will never change tire size. If they did, there'd be a lot of suspension failures in evidence.

 

I heard somewhere? The 4R and Tacoma's suspension/drivelines hold up fine, until you get to a 35" tire.

 

This was my thought, as well. I just don't see/read about parts crapping out due to oversized tires.

I would certainly want to regear if I were going to run 35's! With these 295's, it's not too bad. But, I'll probably regear eventually.

 

V8 should be fine for me with 35s but I’m still going with the nitro 4.56 gears. We got a lot of hills in the PNW

 

I've been pretty satisfied with the 4.0 all around. But, if I somehow acquired a 4.6 + 6 speed auto from a GX, I'd definitely put it in the 4Runner.

 

If I crash the GX I’ll swap the engine and trans in my wife’s 5th gen. Thanks for the idea haha

edit: actually I’ll do a ls swap

 

LS swaps are fun, but I'd take the 4.6 over an LS. If they're half as nice as the 4.7 in my '03 was, it would be a huge upgrade!

 

I don't know if we ever get to this scenario. I see minimum people install Bilstien5100 with bigger tires so hardly anyone has stock Toyota suspension..

 

If the stock suspension is anything like the stock speakers they suck really bad. I changed mine out for Ironman suspension and there is a huge difference in weight and quality feel to it. The stock suspension parts are good enough for daily driving but you hit a dirt trail with corrugated road and the difference might not feel present in the car all that much as a lot helps from deflation of the tires. But they will overheat fast and lead to premature failure as the stock suspension wasn’t meant for that kinda stuff. How suspension comes into play with bigger tires I have no clue. I figured it could come into bigger play with axels and such having to turn heavier tires which could result in broken CV’s.

 

I figured we were talking about more than just the shocks. When I think about suspension, I think about things like bushings, bearings, and ball joints. All of these things can have increased force on them due to larger and heavier tires.

I would think that hub bearings would definitely take some extra abuse with oversized tires, but I also don't really hear about people having to replace them often due to oversized tires.

I think Toyota engineered these parts to take some abuse, so they hold up pretty well even when people modify these trucks.

 

I drove my buddies gx470 lifted on 33s a few days ago. Both 4.6 and 4.7 are solid motors.

 

For sure! The smoothness and the torque are what I miss most about the 4.7.

 

I love how 4.7 Tundra SR5 drove on mountain highways. But wasn't happy with frequent fill-ups. Now its good to see Tundra has a whopping 38gal fuel tank.

 

Mileage was the least of my concern. I wanted reliability.

We had a 2005 tundra crewmax 4.7 and that thing was a beast. Wish we never sold it. It was green and Id still be driving it today.

 

Sticking with 265 because 285 only get .6” clearance on the diff.

 

That's why I went with 295's.

Seriously, though, I went wider and taller for more flotation. Clearance is just part of the reason for oversized tires.

 

Good reasons.

 

That’s why I’m going 35s. Floatation and the joys of cutting up my GX
