POLL 37" tires on 17's vs 18's

[Mototrig]

Buying new tires and ditching the 20" wheels.
Pros and cons for 17's vs 18's. Tire cost, ability to hold the bead when aired down, ect. I air down when I pull my toy hauler through the sand off wash road.

 

[Dunerking]

17’s over here..prefer the little extra sidewall

 

[oldman]

For wheeling go with the 17's Same thought on sidewall, hell on my crawler I'd still be running 15's if I could find tires. and the new brakes would fit.

 

[Lunatic Fringe]

I have 37's on 17" wheels on my F350 and think they not only look better but perform just fine.
I've aired down pretty low on Mexican beaches without issue.

 

[adam909]

18's for the win. 17's make the wheels look baloony, just too much wall on the tire.

 

[brianwhiteboy]

17” on 37” over here. More sidewall, less rubber band.

What can I air down to safely with the truck being close to 11k. I have the bead grip methods. Not for sand but in rock

 

[throttle]

another vote for the 18.

 

[Deckin Around]

Imo
There are A LOT more tire options for the 17’s And those tires are cheaper because they are more mass produced on 17s

My vote would be the Toyo Mt ( one of the few 37s that are 13.5 wide) I ran a few sets of those on trucks and jeep

The one downside I've noticed with 17's are the rim width is only offered in 8.5 to 9. Is that an issue with your 13.5 tire width?

Edit: I ask b/c on my 20x12 rims I run a 13.5 wide tire and air down to 8-9 psi in the rear hauling 10k in the sand. Never had an issue with folding the bead. And plan to do the same on 17's

Smaller rims give you more to work with, It all depends on how much you compress the sidewall against the rim. before i had beadlocks there are tricks to help seal the rim, liquid rubber, duct tape, crap like that. paint this on the sealing surface, it helps keep the rim seated.

 

[rivermobster]

18's for the win. 17's make the wheels look baloony, just too much wall on the tire.

The correct term is "flotation". It's what you want, if you will actually take your truck off road.

Mall crawlers, need not apply.

 

[THE WIDGE]

I have 18’s on 37s, looks great.

 

[Icky]

We camp in the back of wash 4 where's its soft. Megacab with 295/65R20 towing a 18k 40CR, I air down from 80 psi to 55 ish, never had a problem. The one time I got stuck I unloaded my rail and was able to drive away.

 

[Melloyellovector]

17s are a softer ride on and Offroad, but highway fast driving on like the 10 or 91 fast and carpool lanes the flex recovery at speed is wonky as fuck and will make you feel like your on the edge of death wobble but it’s just the tires going boingy. Not great for towing heavy, tail will wag the dog. Even with WDH, airbags, etc there will be times you think WTH
CJC suggests 17s for best ride

18s if your on the street 90% + of the time and tow heavy sometimes. Much more stable on road and still great Offroad
Carli suggests 18s for best ride

20s if you tow heavy often, get true weight of truck abilities and not double fist driving. And still plenty of side wall to air down in sand / rock
cjc and carli suggest 18-20 if tow heavy and need 1 ton abilities. Iv had all 3 sizes on the last 3 trucks in the last 4 years. I wouldn’t do 17s again.

17s w 37

20s w 37

 

[Orange Juice]

I run 20’s on my 2005 dodge Ram SRT.

The best part of running 20’s are in the trucks handling.

Most of the stiff ride comes from 8 ply side wall tires.

 

[Backlash]

My SS had factory 20" wheels which were perfect on that truck. My 1500HD has 17" wheels which I like for this truck. So far I've been REALLY happy with the 8 ply Bridgestone Dueller AT tires in 285/70/17.

 

[satellitemike]

I think I went w 17" from 20" on my 19 F150 and the brake calipers barely fit but loved the improved ride after the change.

 

[D19]

I prefer chrome wheels and they are very little options under 20" so I went with 20s on 37s. This is my 2nd or 3rd truck with that set up. No complaints.

I had a truck with 37s on 17s, I notice zero ride difference from 17-20.

I won't run anything but a Toyo MT.

 

[FROGMAN524]

Much higher load ranges for 18s

 

[Racey]

Much higher load ranges for 18s

This is the big factor. If you want to run Load Range E you better make sure they come in your wheel size.

 

[WildHorses24]

This is the big factor. If you want to run Load Range E you better make sure they come in your wheel size.

I have E rated Toyos on a 17" wheel. 37"x12.50"

Yeah that's why I started this thread to pick all your brains on this. I hadn't thought about the extra sidewall on 17's wagging the dog when towing heavy or 18" tires having better load rating

 

[DarkHorseRacing]

Make sure you’ll clear your brake calipers if you are dropping down in wheel diameter.

 

[Tank0088]

17”. You will have more of a tire selection and I believe tires are cheaper for 17” wheels.

 

[sczagurs]

17” methods with the new Toyo at3 load range E tires for the win on my 350.

 

[dirtslinger2]

17's all day.

Also, you mentioned wheel widths, you will have no problems putting a 13.5" tire on an 8.5 or 9" wheel.

 

[Jimmyv]

20’s and they need to be ‘Spinners!!!!


J/k

17’s ALL DAY on anything ever seeing dirt for all the constructive reasons provided above.

Plenty of E rated options for towing.

 

[Flying_Lavey]

One thing NOBODY has said..... some trucks have large enough brakes that they require an 18" wheel. Something to keep in mind.

 

[HNL2LHC]

If you were in Hawaii this would be the route to take. You don’t even have to worry about rehearing….it is not needed.

 

[c_land]

BFG has an F rated all terrain in 37 for 17” wheels coming. Best of both worlds

https://dgaddcosprod.blob.core.windows.net/b2c-experience-bfg-production/attachments/clz74riy502c701kqq5h7lyvi-v5-bfg-ko3.pdf

Edit. And they have a more narrow 35x11.50 r17 6 ply coming for the 1/2 guys.

 

[Riverbound]

17s w 37s is my preference as I prefer more sidewall. It’s also a more available option which leads to better pricing. But the reality you aren’t going to notice much of a difference between the two except cost.

 

[Deckin Around]

All of them have had off the shelf Method fake beadlock wheels , I never had an issue at 12-15psi in the truck or 8-10 in the jeep.
It doesn’t sound like much but that extra inch of tread width is like 10% more floatation in the sand. Every bit helps

Unlike the 1” in width difference, Imo a preference of 17’s bs 18’s “because I like more/less sidewall” (functionality not looks) is funny to me because you are really talking about 1/2” of sidewall on either side of center hub. Props to whoever can feel that little difference in a lifted truck

Your in Oc with nice freeways

hit the 91 / 215 - from 15 all the way to 60 fastlane or carpool lane, or 15 fast track lane north or south anywhere north of the 91. Have 17s at 65psi and 18s at 65psi. Trust me you’ll know the difference. Both had toyo‘s

Also more body roll with 17s versus 18s. I avg 50k miles a year on trucks and have had nearly every tire combo and lift worth getting.

17s towing 20k lbs and you’ll really remember how much side wall you have.

But if dont drive a lot and don’t tow heavy pigs. Then sure 17s feel more plush for smooth ride, and yes Offroad absolutely make a difference.

 

[OkHallett270]

I went with 18s on 37s, but I voted 17s I went with the 18s because I thought my tire selection was better at 18s. I do like the way a 17 looks better though.

 

[LBsuperJET]

17 Beadgrips on 37x12.50 E's work just fine when towing 5th. I have no clue about towing a TT bumper pull so no wag here. They work great aired down for commuting and work great at 60psi+ for towing the hauler. IMO if you buy and setup smart, you shouldn't have an issue with any of the 3 rim sizes.

 

[ArizonaKevin]

What truck are they going on? My raptor has 18" wheels on it and I'd love to swap down to 17s because the only 37/12.5r18 I can find are load range E. I have to stick with 35s to get a load range D comfy sidewall. If it's going on a 3/4 ton that's doing a lot of towing, different story.

 

[endobear]

17"
Alot of sidewall does great aired down in the sand.

 

[Riverbound]

For the desert I run 15s with 35s around 10 psi 7 in the sand.

Why in the world are you running 65psi in the tires? Are you loaded down? Most tires around that size have a load capacity of 2000+ lbs each at 35 psi. Go up to 40 and it typically goes up an additional 200 lbs.

I'd suggest looking up your load rating table for your tires and adjust cold PSI accordingly. You'll get more life and a better ride.

The truck is 02 F250 7.3 CC
I have to run E rating for towing. The truck already rides like a forklift, on 20's it's even worse. I want 17's for better ride quality.
As stated earlier though I'm splitting hairs as the difference between 18 and 17 is only a half inch below the rim.

I overthink everything, just like right now.

yeah in your case it doesn't really matter. In my case, it matters a lot

 

[HgH Vltg]

We did 17's on 39's on the boss mans new tremor. 17's until you can't haha.

 

[CLCookie]

When I see any truck running 20's, first thought is mall crawler. I personally run 17" for off roading purpose, I always air down for the ride in the dirt. Air down 20's and you suspectable to rocks more.

35" on 16" wheels for me. 4.5" Donahoe Racing lift.
As mentioned. She can start to wag pretty good, even with E rated tires pumped up to max psi, air bags, sway bars and eqaulizers tugging 13k.
Aired down to 20psi, she floats in the sand.

Discount tire guys jacked one my tires up fixing a leak. No biggie. I have road Hazzard. But they don't make my tire anymore and my other 3 tires have plenty of life left. FMe.

Then, they proceeded to tell me that they can't find any 16", E rated ATs in a 35 in Denver.
And that I have a rare wheel size. Weren't rare when I bought them 22 year's ago.

Nice rig!!!!

 

[Mototrig]

All the way in the back of wash 13. It gets silly soft back near the small dunes.
My tires look almost flat at 8-9 psi whiled hooked to the trailer but it's like having tank treads in the rear.

 

[callbob]

35s On 17” rims. But it’s on a jeep, don’t tow anything it gets towed. Kenda Klevers about a hundy cheaper each than toyos or anything comparable. Load range E and 10 ply but doing trails in Ouray at 25 pounds they were one of the best tires I have ever run on any of my jeeps. Guy I was running with had a Rubi gladiator and had to lock in a couple of times and I walked right up.
