How Much POWER Do You Lose with 35-Inch Tires? Dyno Numbers on a 3rd gen Tacoma!

[@InGratitudeIam]

This is really good to know. I think you'll find that with 35" tires, added weight, and no regear, stress on the steering rack and drivetrain go up quite a bit. Stuff starts to bend and break offroad more often. You've gone beyond what the engineers at Toyota envisioned. Once you hit 34" tires, it takes the same amount of effort as fitting 35's. I have a 2016 4R and went to 33" Pizza Cutters (255/80R17) on OEM TRD Pro wheels. Offroad traction is amazing. I kept the lift to 2.5". I did not need a BMC or trim inside the wheel well. Nothing rubs. Because of added weight with my loadout, I regeared to 4.56. After the regear, the truck became more responsive, and I gained 2 MPG. My components are happy. A friend of mine went to 35's, BMC, more weight, etc., regear and Magnusson. Between the two, it feels like most of the performance gain came from the regear. Yes, his truck is a little quicker. At an additional $10,000 for the Magnusson, plus the cost of the body work, plus added maintenance, higher fuel costs, the increased stress on parts he has from the 35's and the Magnusson aren't worth it to me. YMMV.

Wow, about 50 horsepower. I wasn't expecting that much. 4Runner owner here on 33s, and was thinking about going to 34s. You gave me some good things to think about before I make that switch. Thanks again for the content and the time that you put in for this.

Nice video - Would be cool to compare those numbers to a 33 -inch tire, a tune, and also to see what it looks like on a truck that is geared with 4.88 or 5.29's

[@fouUili684]

This was good to see thank you, it’s common knowledge or so I thought but thanks for doing a visual. I hope you do that with a line of vehicles like the previous generation tundra on stock wheels and tires vs 35s.

[@1Larriva]

But you gain 150 hurspurrs from the looks

[@edfig]

Great video. Looking forward to the other modifications to see if it improves power.

[@hongsitu3429]

Be interesting to see how much power it saps with the same size wheels and tires but one setup is maybe 10 to 15lbs lighter

[@MatthewFreeman-s5o]

Id be interested in seeing the same truck now on the dyno with those 35's and 5.29's no tune then tune.

[@stephencarbajal5657]

Great video and that's definitely eye opening. 😳 with the transmission shifting i wonder what the overall performance experience be like with 35's? I know tuning helps ?

[@VentureOutMoreJon]

Great video. Thanks man

[@benruthlessburger8905]

Good video and info

[@teamhonzilla]

You could also reduce the weight with a lighter wheels like Rays wheels

[@rougecampos317]

What kind of rack is that

[@Alex-tq1ph]

Can you do this test with the 2024 Tacoma also? Great video!

[@erod6468]

🤢🤮

[@1tzKev1n]

is this truck on stock gears? would a regear help with the power or no?

[@trailrunnah8886]

Definitely. The big tires are heavier and take more energy to spin, and screw up your gearing so that your engine is not operating in the RPM range that it was designed to. Plus, the crawl ratios on these trucks aren't great even with stock tires, so gearing is a help in that aspect as well.

[@tiffanynguyen412]

More power 🎉🎉🎉🎉

[@BK3411]

Does anyone know what brand bumper this Tacoma has? Like how it doesn't cover the front sensor.

[@davesantimaw5413]

My FJ is on 33s and this analysis continues to discourage me to go with 35s for overlanding. Plus I don’t want to re-gear the FJ with 35s.

[@wrm787]

Have you thought about retuning? It might be a badge over the actual issue but I heard it does the trick and reasonably price. Curious to see what other's think.

[@davesantimaw5413]

@@wrm787 Not sure what retuning is; can you please explain?

[@wrm787]

@@davesantimaw5413it’s like adding the pedal commander but better. From my understanding you’re reprogramming your vehicles computer for more “umph” running beefier tires or having heavier load. Don’t get me wrong we ain’t making the 4Runner into a sport car but helping it on gear search and torque

[@davesantimaw5413]

@@wrm787 Never heard of this but you would have to have a body shop that knows what they’re doing messing with your onboard computer. I’ll ask my shop as they’re wanting $2k just to re-gear to a 4.88.

[@wrm787]

Super interested on the Regear video coming! What are your honest thoughts on just retuning with beefier tires or adding more weight??

[@trailrunnah8886]

Re-Gearing is definitely the proper way. Besides putting your engine back into the proper operating RPM, it helps the crawl ratio. Even with stock tires the crawl ratio on these things is not great. Cold air intakes and exhaust are basically useless l, you get high RPM power with those, which is not what you need in an off-road vehicle. And you could re-gear twice for what a supercharger cost, and even then you're still not in the correct RPM range. Or think about drag race cars. It's a different application of course, but they make loads of HP yet still run gearing match to the engine's power curve.

[@project_poor_runner]

Tag me when the regear video goes live please 🤘🏼

[@Dayota___]

So do I still need to regear if I run 35’s? Frankly I need a straight up opinion

[@PortugieDan]

Yes, without a doubt. I just put 5.29s in my truck 2 weeks ago and went on a 100 mile trip. I have 34" tires and it is a night and day difference in available power, gear shifting, and my gas mileage increased by 2 mpg over 200 miles.

[@HarryKuloh]

​@@Dayota___the truth is that pizza cutter wheels have so many benefits AND more traction. Yet no one seems to be aware of it for many reasons.

[@overland_cam]

Yes

[@bigdave5946]

Lose of HP along with MPG’s

[@hiluxmax2709]

"Regearing might not be worth it". Such an unproffesional comment and advice. Going to 35s affects your crawl ratio offroad if you value your offroading. Also with the 6 speed gearbox, it's harder for the taller gears to engage on the road, will engage at higher speeds, and you use more fuel at normal speeds before that. Rehearing is definitely worth it. Don't fall for the bank factor of fitting 35s, do it properly. Your vehicle will thank you and you'll have a lot less stress of the drivetrain.

[@Ashoud_Anobetah]

Regearing is still not worth it..adding 30 to 50lbs extra on each wheel with bigger tires and not expecting fuel economy to drop😅😅😅😅

[@hiluxmax2709]

@@Ashoud_Anobetah you can still put bigger tyres on and get better fuel economy with the right regear.
