Wanting 33” Tire - TRD Pro

So I want to get 33” tires on my 2020 TRD Pro.

I ordered the Westcott TRD Pro lift kit to maintain the components that come standard on the Pro and give me the room I need to add the tires without rubbing.

I’m about to order the tires from Tirerack.com today but want to make sure I’m not missing anything as this is the first time I’m doing anything like this.

I’m ordering the 285/75/16 KO3’s.

I guess my main concern is, do I need to worry about the E load rating? Anything else I need to be aware of?

 

Imo e load is overkill. I personally like c load for my use. There have been many people who put that size tire on the pro wheels and fit without modification or trimming to the truck. Without lift even. Possibly remove mud guards but that's about it. Goodluck.

 

The only load rating I see offered is the E rating. Do they make different types of loads for each tire?

 

Load range C will be available for that tire on Aug 15. Think I should wait?

 

An E load tire will likely be stiffer all around than a C load tire. It depends somewhat on the manufacturer.

Lift doesn't provide clearance for tires. Lift just delays when they'll rub, if they're going to rub.

 

I run E loads and just keep my pressures a bit on the lower side and it's a bit rougher but It's not miserable by any means. Since they are far more available and easier to find most of the time.

The difference from to c to e is not that great if you go sl to e it's a huge difference. Some companies offer a 285 in an sl casing rather than c or e.

Assuming you have the stock pro wheel you really should just need a custom alignment to gain a touch of added cab mount clearance. I would skip the collar lift as lifts don't add clearance anywhere but at ride height and they can often reduce clearance if not aligned properly afterwards.

Another option that is the easiest since the stock wheel is narrow enough is to go the skinny route of a 255/85r16. I believe there isn't a huge availability in this size but there are some at's and mt's out there. Much more options in the 17".

 

Thanks for the reply. The way I understood was that a lift was needed, but I did also want to be a little higher as well as I like the look. I thought the Westcott was a good fit because of maintaining Pro suspension, without an obnoxious lift.

 

I went through 2 sets of Erated Geo MT’s 33’s thank god I’ve switched back To SL if ride quality is important to you. Also SL rated has more load rating then c rated trust me I’ve looked. Also I’ve ran tons of trails and some moderate trails with SL no issues at all. I slashed a side wall on my previous Geo MT’s LOL. LIKE I said if ride quality is important to you weigh out your options.

 

The tire takes the same amount of space, no matter where in the suspension travel it is, or if the wheels are turned. A 2" lift means that you have 2" more of travel before they rub.

Spacers will give you lift, but they add nothing to suspension performance. If you never get into a position of bottoming your suspension, you'll be OK. If you do bottom, it may just be the shock that is bottoming, not the bumpstop. Bottoming the shock could destroy the shock. If you're lucky, it only bends.

 

E-rated tires are built to have a higher load-carrying capacity than C-rated tires. To achieve this higher load carrying capacity, they have thicker sidewalls.

A lot of people in "mid-size" 4x4s (Tacoma, 4Runner, Wrangler) prefer C-rated tires because they aren't as stiff. An E-rated tire will be quite firm on the road in a mid-size. However, the thicker sidewalls found in E-rated tires will stand-up to off-road abuse better than the thinner sidewalls of a C-rated tire. So - if you are choosing between the two - you need to prioritize either the on-road or off-road driving experience.

I had a pretty nice suspension on my 2017 Tacoma (Icon Stage 5 with remote reservoirs). As a consequence, I could run E-rated tires and still have a really good ride on-road. This gave me the best of both worlds: a strong tire that was more puncture resistant off-road, with a really good ride on-road due to the aftermarket suspension. I really appreciated the added peace of mind that thicker sidewalls provide when driving on rocky trails.

If you have a TRD Pro that's a pretty nice suspension. You can probably run E-rated tires without suffering from a harsh ride on-road. But on-road ride is a subjective thing: some people have greater tolerance for a stiff ride than other people.

 

Probably going to want to service those shocks if haven’t already.

 

Yes.

 

Those K03's look great but are also crazy heavy. With 33s 0mm offset wheels are aftermarket UCA's for additional caster are your friend.

 

While not necessarily incorrect, this is far from the full picture.

Load rating used to be based on # of plys, more plys would typically increase sidewall thickness and increase load capacity. This is an antiquated concept because things have gotten much, much more complex.

Material technology has advanced massively so load handling ability and sidewall durability (these are different things despite historically being correlated to each other by old school off roaders) is not necessarily tied to "thickness". The materials themselves play a huge role. Imagine two different materials, one being 3mm thick, the other being 5mm thick but the thinner material is actually stronger than the thicker one. An analog to this is that a piece of steel and a piece of aluminum of the same thickness do not have the same strength.

You could also design a tire, utilizing certain materials and construction methods, for different things. Designing a tire for load carrying vs for off road grip and durability are two very different things.

I wish I had been able to take measurements but the sidewalls on my C load AT4W felt as thick, or possibly thicker, than my E load G003's. But the G003's had a significantly higher load rating and was MUCH stiffer in terms of ride quality and ability to air down to get better tire deformation. My guess is that the two sidewalls are pretty equal in terms of off road durability but clearly not equal in load handing.

 

My 33" E load pizza cutters are sooooo convenient. They dont rub, they don't wear out your front end components, I get to keep my oem mud flaps, and I don't need to regear.

Did I mention I have gobs of ground clearance?

 

I’ve only ever run E rated tires on my Tacoma and I won’t go back. I’m also on LT285/85/16s and it’s a great size.

The truck is my daily driver and I do ~25K miles a year. E rated 33’s would be just fine.

 

Pizza cutters FTW! I love my 255 AT4W's.

 

Where did you hear this? BFG site isn't showing it....

 

What is your taco's use? - Consider staying with SL.

They handle more load than you'd ever want to without bogging you down with un-necessary un-sprung weight.

No issues aired down on rough terrain for long periods.

Save your suspension, your MPGs, and your teeth!

E rated tires? - maybe for an F-350 with a flat bed carrying bricks for a living!
