DIRTY SEVEN CLUB

17s

 

Can’t lose with twenty-toos…. Lol.

17” or 18” are both great. Remember, lots of the 17” options are 8.5 wide. Most 18” options will be 9 wide. Either is fine, but offset numbers won’t mean the same when comparing the two.

 

Yea i been back and forward and still not sure which one. I'm leaning towards the 18" more seems like a happy medium. I like these AGP wheels.

 

So long as the backspacing (offset?) is good, that’s a nice looking wheel.

 

+18

 

17s man! more cushin for the pushin

 

Joined the club this past week.
Nitto Ridge Grappleres 37x12.5 r17
Black Rhino Rapids 17x8.5 10 mm offset powder coated jet/wet black.
DRT Cab Mount Relocation Kit done as well. Still need to trim plastic liner as I do rub turning uphill.
(wanted Toyo OC R/T Trails but couldn't get them in time)

 

nice work. Looks great

what running boards are those?

 

Go Rhino RB20's (regular version, not the slims') mounted in reverse so they get larger width wise closer to the bed.

 

right on. Look great

 

Finally stepped to 37s. New wheels at the same:

Wheels: 17x9 +18 Fittipaldi Off Road FBF804 forged beadlocks
Tires: 37x12.50R17 Falken Wildpeak R/T

Finally looks right!

Damn that’s Beautiful. (love the background too)

 

Wow that is sexy. The voodoo blue of all the colors Toyota has done pops better than them all.

 

Question on those 37s. With them being so big and heavy compared to the stock tires, do you notice a pretty significant difference in your acceleration and braking? I currently have 285/70/18 Ridge Grappler's on my Tundra that will need replacing this year, and I am thinking about going to 35s.

 

tires are 80 lbs
Wheels are 23 lbs
So 103 per corner.

yes I notice acceleration is slower for sure. The supercharger and 5.29s help a lot but it’s noticeable from my last set up of 295/70/r18s

Breaking not really much at all. As soon as I let up on the gas, the truck wants to slow down on its own. (Compared to my dads Chevy cruise I used all last week, that car would just coast and barely lose any speed.)

 

There's more options on tires with 17s, both manufactures and load indexes.

 

I run the lightest 37 setup I could easily find (load range c BFG Ko2s, and Rock Warrior wheels) and with 5.29s I find performance to be more than adequate for a truck this large.

 

I'll play contrarian here just a bit. I drive my truck on stock 4.30 gears and then at the drop of the hat I can hop in my dad's bone stock truck so I can get a very apple to apples comparison. My wheel-tire combo is also right about 100 lbs per corner, my dad's truck should be in the range of 75-80lbs per corner, and I can feel that in braking and coasting. When I drop the stock truck into S-mode and downshift to avoid breaking it will slow down noticeably quicker than my truck on 37s and you can also feel the weight difference in the brake pedal. The rolling inertia of the 37s is pretty apparent when you can jump back and forth at the drop of the hat.

Now, that being said there are zero issues with this for me. My truck is still perfectly acceptable at braking and coasting (I can also see over more traffic and plan earlier which I really like) it is just not the same as a stock truck. Both of the other trucks have 5.29 gears which plays a huge role in this, and their coasting performance would be much better than mine, but straight up tire vs. tire it is a noticeable difference to me.

 

I run same tires except with different wheels, the calculation shows it takes additional 2lb.ft (2.7kn.m) per corner to accelerate at the same rate to 100km/h as I did on 285/75r18s.

the c-load 37s with wheel turned out to be 7lbs lighter per corner over stock BBS wheel + AT3W in skinny 35s.

 

Yea, probably going to have to hit the research again and see what offset is good on a 17" wheel.

 

Highly tire make/models dependent too, with ko2s and 17x8.5 et0, there's tons of room, but true 37s will probably be more tight.

 

Et0 stick out like 2" I believe correct? I'm not a fan of lots of poke

 

BTW an OTT Tune will bring the truck back to life

 

This is 17x8.5 et0, tires are 37x12.5r17

 

Word from the wise, remove the diff drop and carrier bearing drop!

 

Why would you remove the carrier bearing drop?

 

This! I removed both on mine.

I could explain it, but the 2nd video will explain a lot with scientific reasoning.

 

I get the logic behind no diff drops, but what’s wrong with a carrier beating drop?

 

Excellent points, guess I'll be leaving mine out when I do my suspension. Also have to see what offset he is using with his 37". He has a good point on stress with lower offset.
