Largest Functional Tire Without Mods

[Tom109]

Here are a few options in 255/80 R17 (33 x 10 inches)

• Cooper ST MAXX / 32.8 x 10.2 / E / Q (up to 99 mph) / 18.5/32" tread depth / 58 pounds
• Nitto Ridge Grappler / 33.3 x 10.0 / E / Q (up to 99 mph) / 16.5/32" tread depth / 55 pounds
• Toyo Open Country AT 3 / 33.1 x 10.0 / E / R (up to 106 mph) / 16.3/32" tread depth / 53 pounds
• Falken Wildpeak AT3W / 33.1 x 10.0 / E / S (up to 112 mph) / 17/32" tread depth / 52.5 pounds

The Toyo R/T Trail 255/80R17 has floated to the top of my list.

@anand loves the pizza cutters!

Same. Kind of wished had option for even a size (inch) smaller rim with say a 255/85/16

 

[AZGrenadier]

This may sound like a dumb question but are all e rated tires 10 ply, d rated 8 ply?

 

[AZGrenadier]

Has anyone done a 285/75r17? Just a little taller?

Alas the brakes are too large for a 16" wheel....

More or less, but from a long drawn out podcast I listened to last year.... In modern times "ply" ratings don't actually directly equate to the number of plies as they may have 30 years ago, but more so a generalized thickness of the material.

This has been done, if memory serves me correctly it was a Donny Grey on Methods...

The sidewalls of tires are no longer 10-ply or 8-ply or really any-ply

Those designations go back to an earlier time when the numbers actually corresponded to the number of plies in the sidewalls. Today, we keep those terms but they really are just place-holders for sidewall strength. So E-rated tires are described as 10-ply, but, in fact, most have three distinct layers or plies.

Here are the Load Ratings for tires (the letter on the left), and the equivalent number of plies (the number on the right) - based on the older design of tires:

A 2
B 4
C 6
D 8
E 10
F 12
G 14
H 16
J 18
K 20
L 22
M 24
N 26

I was going to get them but very rare tyres size in Aust so impossible to get for overlanding locations

I was thinking about this tire size for the Grenadier after I go through the factory ones. I run them on my 2” lifted 2016 F150 on 17 rims, it’s essentially a 34x11.5, so an inch shorter and inch narrower than the standard 35x12.50 everyone compres to off-road . Those 2 inches come in handy for fitting well and not rubbing, and for being able to use factory rims.

It is a weird size, but compared to 5-7 years ago when I first started using them there are a lot more options now.

I just put on 385 70R 18 Toyo's. If you go larger, you may have to use a spare tire extender plate.

 

[Krabby]

285?

 

[Rocky10]

285?

285 silly me

 

[Krabby]

285 silly me

I figured - although an IG on 38s would look interesting!

That's a 39-inch tire! Obviously just a typo

285/70 R18 is about 33.7 inches in height. After mounting the tires, did you cycle the suspension to check for rubbing?

Do you notice any rubbing on road? A 90-degree turn onto a small on-ramp (like turning into a parking lot or driveway) will often cause the front tire on the inside of the turn to rub on the rear fender well - if the tire is too large.

Do you notice any rubbing off-road when approaching full articulation?

Thanks in advance!

Looks great! ?

However, I want a tire which
- is noiseless
- comfortable
- robust
- good for Mud, Tarmac, Gravel and whatsoever
- has an excellent performance in summer, winter, snow, on ice and in the rain
- looks good
- is good for 70000 kms
- and doesn't cost much.

Any ideas? ?

just went with 285/65-18 BFGoodrich KO2

Goose gear is going to try some 285/7517 on Methods.

I will watch with interest on this one, I am loving the photos starting to come out now with small lifts and aftermarket wheels and bigger tyres.

Whilst I would love to do it to mine, I can’t warrant the expense if I am honest and wouldn’t see any real benefit to my driving, would look awesome though.

 

[AZGrenadier]

Agile Offroad mounted 285/75r17. He said after a day of wheeling there was no rubbing but wouldnt guarantee it definitely wouldn’t rub. No lift.

I have some clearance photos. These are the 285 70R 18. No Clearance issues. It's close
